Reading from Solr

+ * + *

{@link SolrIO#read SolrIO.read()} returns a bounded {@link PCollection + * PCollection<SolrDocument>} representing Solr documents. + * + *

To configure the {@link SolrIO#read}, you have to provide a connection configuration + * containing the Zookeeper address of the Solr cluster, and the collection name. The following + * example illustrates options for configuring the source: + * + * 

{@code
+ * SolrIO.ConnectionConfiguration conn = SolrIO.ConnectionConfiguration.create("127.0.0.1:9983");
+ * // Optionally: .withBasicCredentials(username, password)
+ *
+ * PCollection docs = p.apply(
+ *     SolrIO.read().from("my-collection").withConnectionConfiguration(conn));
+ *
+ * }
+ * + *

You can specify a query on the {@code read()} using {@code withQuery()}. + * + *

Writing to Solr

+ * + *

To write documents to Solr, use {@link SolrIO#write SolrIO.write()}, which writes Solr + * documents from a {@link PCollection PCollection<SolrInputDocument>} (which can be bounded + * or unbounded). + * + *

To configure {@link SolrIO#write SolrIO.write()}, similar to the read, you have to provide a + * connection configuration, and a collection name. For instance: + * + * 

{@code
+ * PCollection inputDocs = ...;
+ * inputDocs.apply(SolrIO.write().to("my-collection").withConnectionConfiguration(conn));

Subject: [PATCH 021/578] Add client-side throttling.

The approach used is as described in
https://landing.google.com/sre/book/chapters/handling-overload.html#client-side-throttling-a7sYUg
. By backing off individual workers in response to high error rates, we relieve
pressure on the Datastore service, increasing the chance that the workload can
complete successfully. This matches the implementation in the Java SDK.

Subject: [PATCH 026/578] Updates ByteKeyRangeTracker so that
 getFractionConsumed() does not fail for completed trackers.

After this update:
* getFractionConsumed() returns 1.0 after markDone() is set.
* getFractionConsumed() returns 1.0 after tryReturnRecordAt() is invoked for a position that is larger than or equal to the end key.

This is similar to how getFractionConsumed() method of OffsetRangeTracker is implemented.

+# Running NexMark on Beam on Flink on Google Compute Platform
+
+Here's how to create a cluster of VMs on Google Compute Platform, deploy
+Flink to them, and invoke a NexMark pipeline using the Beam-on-Flink
+runner.
+
+These instructions are somewhat baroque and I hope they can be
+simplified over time.
+
+## Prerequisites
+
+You'll need:
+
+* the Google Cloud SDK
+* a clone of the Beam repository
+* a Flink binary distribution
+* a project on Google Compute Platform.
+
+## Establish the shell environment
+
+```
+# Beam root
+BEAM=
+# Flink root
+FLINK_VER=flink-1.0.3
+FLINK=
+# Google Cloud project
+PROJECT=
+# Google Cloud zone
+ZONE=
+# Cloud commands
+GCLOUD=
+GSUTIL=
+```
+
+## Establish VM names for Flink master and workers
+
+```
+MASTER=flink-m
+NUM_WORKERS=5
+WORKERS=""
+for (( i = 0; i < $NUM_WORKERS; i++ )); do
+  WORKERS="$WORKERS flink-w-$i"
+done
+ALL="$MASTER $WORKERS"
+```
+
+## Build Beam
+
+```
+( cd $BEAM && mvn clean install )
+```
+
+## Bring up the cluster
+
+Establish project defaults and authenticate:
+```
+$GCLOUD init
+$GCLOUD auth login
+```
+
+Build Google Cloud Dataproc cluster:
+```
+$GCLOUD beta dataproc clusters create \
+  --project=$PROJECT \
+  --zone=$ZONE \
+  --bucket=nexmark \
+  --scopes=cloud-platform \
+  --num-workers=$NUM_WORKERS \
+  --image-version=preview \
+  flink
+```
+
+Force google_compute_engine ssh keys to be generated locally:
+```
+$GCLOUD compute ssh \
+  --project=$PROJECT \
+  --zone=$ZONE \
+  $MASTER \
+  --command 'exit'
+```
+
+Open ports on the VMs:
+```
+$GCLOUD compute firewall-rules create allow-monitoring --allow tcp:8080-8081
+$GCLOUD compute firewall-rules create allow-debug --allow tcp:5555
+```
+
+Establish keys on master and workers
+**CAUTION:** This will leave your private key on your master VM.
+Better would be to create a key just for inter-worker ssh.
+```
+for m in $ALL; do
+  echo "*** $m ***"
+  $GCLOUD beta compute scp \
+    --project=$PROJECT \
+    --zone=$ZONE \
+    ~/.ssh/google_compute_engine.pub $m:~/.ssh/
+done
+$GCLOUD beta compute scp \
+  --project=$PROJECT \
+  --zone=$ZONE \
+  ~/.ssh/google_compute_engine $MASTER:~/.ssh/
+```
+
+Collect IP addresses for workers:
+```
+MASTER_EXT_IP=$($GCLOUD compute instances describe \
+ --project=$PROJECT \
+  --zone=$ZONE \
+  $MASTER | grep natIP: | sed 's/[ ]*natIP:[ ]*//')
+MASTER_IP=$($GCLOUD compute instances describe \
+ --project=$PROJECT \
+  --zone=$ZONE \
+  $MASTER | grep networkIP: | sed 's/[ ]*networkIP:[ ]*//')
+WORKER_IPS=""
+for m in $WORKERS; do
+  echo "*** $m ***"
+  WORKER_IP=$($GCLOUD compute instances describe \
+    --project=$PROJECT \
+    --zone=$ZONE \
+    $m | grep networkIP: | sed 's/[ ]*networkIP:[ ]*//')
+  WORKER_IPS="$WORKER_IPS $WORKER_IP"
+done
+```
+
+Configure Flink:
+```
+cat $FLINK/conf/flink-conf.yaml \
+  | sed "s|.*\(jobmanager.rpc.address\):.*|\1: $MASTER_IP|g" \
+  | sed "s|.*\(jobmanager.heap.mb\):.*|\1: 4096|g" \
+  | sed "s|.*\(taskmanager.heap.mb\):.*|\1: 8192|g" \
+  | sed "s|.*\(parallelism.default\):.*|\1: $(($NUM_WORKERS * 4))|g" \
+  | sed "s|.*\(fs.hdfs.hadoopconf\):.*|\1: /etc/hadoop/conf|g" \
+  | sed "s|.*\(taskmanager.numberOfTaskSlots\):.*|\1: 4|g" \
+  | sed "s|.*\(jobmanager.web.submit.enable\):.*|\1: false|g" \
+  | sed "s|.*\(env.ssh.opts\):.*||g" \
+  > ~/flink-conf.yaml
+cat $FLINK/conf/log4j.properties \
+  | sed "s|.*\(log4j.rootLogger\)=.*|\1=ERROR, file|g" \
+  > ~/log4j.properties
+echo "env.ssh.opts: -i /home/$USER/.ssh/google_compute_engine -o StrictHostKeyChecking=no" >> ~/flink-conf.yaml
+echo "$MASTER_IP:8081" > ~/masters
+echo -n > ~/slaves
+for ip in $WORKER_IPS; do
+  echo $ip >> ~/slaves
+done
+cp -f \
+  ~/flink-conf.yaml \
+  ~/masters ~/slaves \
+  ~/log4j.properties \
+  $FLINK/conf/
+```
+
+Package configured Flink for distribution to workers:
+```
+( cd ~/ && tar -cvzf ~/flink.tgz $FLINK/* )
+```
+
+Distribute:
+```
+$GSUTIL cp ~/flink.tgz gs://nexmark
+for m in $ALL; do
+  echo "*** $m ***"
+  $GCLOUD compute ssh \
+    --project=$PROJECT \
+    --zone=$ZONE \
+    $m \
+    --command 'gsutil cp gs://nexmark/flink.tgz ~/ && tar -xvzf ~/flink.tgz'
+done
+```
+
+Start the Flink cluster:
+```
+$GCLOUD compute ssh \
+  --project=$PROJECT \
+  --zone=$ZONE \
+  $MASTER \
+  --command "~/$FLINK_VER/bin/start-cluster.sh"
+```
+
+Bring up the Flink monitoring UI:
+```
+/usr/bin/google-chrome $MASTER_EXT_IP:8081 &
+```
+
+## Run NexMark
+
+Distribute the Beam + NexMark jar to all workers:
+```
+$GSUTIL cp $BEAM/integration/java/target/java-integration-all-bundled-0.2.0-incubating-SNAPSHOT.jar gs://nexmark
+for m in $ALL; do
+  echo "*** $m ***"
+  $GCLOUD compute ssh \
+    --project=$PROJECT \
+    --zone=$ZONE \
+    $m \
+    --command "gsutil cp gs://nexmark/java-integration-all-bundled-0.2.0-incubating-SNAPSHOT.jar ~/$FLINK_VER/lib/"
+done
+```
+
+Create a Pubsub topic and subscription for testing:
+```
+$GCLOUD alpha pubsub \
+  --project=$PROJECT \
+  topics create flink_test
+
+$GCLOUD alpha pubsub \
+  --project=$PROJECT \
+  subscriptions create flink_test \
+  --topic flink_test \
+  --ack-deadline=60 \
+  --topic-project=$PROJECT
+```
+
+Launch!
+**NOTE:** As of flink-1.0.3 this will throw a `NullPointerException`
+in `org.apache.beam.sdk.io.PubsubUnboundedSink$WriterFn.startBundle`.
+See Jira issue [BEAM-196](https://issues.apache.org/jira/browse/BEAM-196).
+
+```
+$GCLOUD compute ssh \
+  --project=$PROJECT \
+  --zone=$ZONE \

+```
+
+## Teardown the cluster
+
+Stop the Flink cluster:
+```
+$GCLOUD compute ssh \
+  --project=$PROJECT \
+  --zone=$ZONE \
+  $MASTER \
+  --command "~/$FLINK_VER/bin/stop-cluster.sh"

  • {@link Person} represents a person submitting an item for auction and/or making a bid

+ * An implementation of the 'NEXMark queries' for Google Dataflow.
+ * These are 11 queries over a three table schema representing on online auction system:
+ * 
    
+ * 
  • {@link Person} represents a person submitting an item for auction and/or making a bid
+ * on an auction.
+ * 
  • {@link Auction} represents an item under auction.

  • {@link Bid} represents a bid for an item under auction.

We synthesize the creation of people, auctions and bids in real-time. The data is not

  • We accept the highest-price, earliest valid bid as the winner.

  • We calculate the averages oven a sliding window of size {@code windowSizeSec} and

+# NEXMark integration suite
+
+This is a suite of pipelines inspired by the 'continuous data stream'
+queries in [http://datalab.cs.pdx.edu/niagaraST/NEXMark/]
+(http://datalab.cs.pdx.edu/niagaraST/NEXMark/).
+
+The queries are over a simple online auction system with tables of
+**Person**, **Auction** and **Bid** records.
+
+The queries are:
+
+* **Query1**: What are the bid values in Euro's?
+  Illustrates a simple map.
+* **Query2**: What are the auctions with particular auction numbers?
+  Illustrates a simple filter.
+* **Query3**: Who is selling in particular US states?
+  Illustrates an incremental join (using per-key state) and filter.
+* **Query4**: What is the average selling price for each auction
+  category?
+  Illustrates complex join (using custom window functions) and
+  aggregation.
+* **Query5**: Which auctions have seen the most bids in the last period?
+  Illustrates sliding windows and combiners.
+* **Query6**: What is the average selling price per seller for their
+  last 10 closed auctions.
+  Shares the same 'winning bids' core as for **Query4**, and
+  illustrates a specialized combiner.
+* **Query7**: What are the highest bids per period?
+  Deliberately implemented using a side input to illustrate fanout.
+* **Query8**: Who has entered the system and created an auction in
+  the last period?
+  Illustrates a simple join.
+
+We have augmented the original queries with five more:
+
+* **Query0**: Pass-through.
+  Allows us to measure the monitoring overhead.
+* **Query9**: Winning-bids.
+  A common sub-query shared by **Query4** and **Query6**.
+* **Query10**: Log all events to GCS files.
+  Illustrates windows with large side effects on firing.
+* **Query11**: How many bids did a user make in each session they
+  were active?
+  Illustrates session windows.
+* **Query12**: How many bids does a user make within a fixed
+  processing time limit?
+  Illustrates working in processing time in the Global window, as
+  compared with event time in non-Global windows for all the other
+  queries.
+
+The queries can be executed using a 'Driver' for a given backend.
+Currently the supported drivers are:
+
+* **NexmarkInProcessDriver** for running locally on a single machine.
+* **NexmarkGoogleDriver** for running on the Google Cloud Dataflow
+  service. Requires a Google Cloud account.
+* **NexmarkFlinkDriver** for running on a Flink cluster. Requires the
+  cluster to be established and the Nexmark jar to be distributed to
+  each worker.
+
+Other drivers are straightforward.
+
+Test data is deterministically synthesized on demand. The test
+data may be synthesized in the same pipeline as the query itself,
+or may be published to Pubsub.
+
+The query results may be:
+
+* Published to Pubsub.
+* Written to text files as plain text.
+* Written to text files using an Avro encoding.
+* Send to BigQuery.
+* Discarded.
+
+Options are provided for measuring progress, measuring overall
+pipeline performance, and comparing that performance against a known
+baseline. However that machinery has only been implemented against
+the Google Cloud Dataflow driver.
+

Subject: [PATCH 041/578] Fix Queries tests

Workaround for issue #22 + extra cleaning

Replace junit asserts by hamcrest asserts
Set numEvents in test to the minimum number that makes the tests pass
issue #15

comments, improve asserts (hamcrest), reformat

For now make generate monothreaded

Subject: [PATCH 052/578] Remove NexmarkDrivers and make execution
 runner-agnostic

This configuration should be external to the benchmark to avoid
unexpected dependencies and to have a more Beam like
(runner-independent) apprach.

Add maven profiles to execute NexMark in the different runners

Fix compile after extra PubSubIO refactor and remove PubsubClient.
PubsubClient was used to create and reuse topics, this logic should not
be part of Nexmark because this add extra complexity/dependencies. A
simple script should do this, or the user should provide the
corresponding topics.

-/**
- * An implementation of the 'NEXMark queries' for Google Dataflow.
- * These are multiple queries over a three table schema representing an online auction system:
- * 
    
- * 
  • {@link Person} represents a person submitting an item for auction and/or making a bid
- * on an auction.
- * 
  • {@link Auction} represents an item under auction.
- * 
  • {@link Bid} represents a bid for an item under auction.
- * 

- * The queries exercise many aspects of streaming dataflow.
- *
- * 
We synthesize the creation of people, auctions and bids in real-time. The data is not
- * particularly sensible.

- *

-# Running NexMark on Beam on Flink on Google Compute Platform
-
-Here's how to create a cluster of VMs on Google Compute Platform, deploy
-Flink to them, and invoke a NexMark pipeline using the Beam-on-Flink
-runner.
-
-These instructions are somewhat baroque and I hope they can be
-simplified over time.
-
-## Prerequisites
-
-You'll need:
-
-* the Google Cloud SDK
-* a clone of the Beam repository
-* a Flink binary distribution
-* a project on Google Compute Platform.
-
-## Establish the shell environment
-
-```
-# Beam root
-BEAM=
-# Flink root
-FLINK_VER=flink-1.0.3
-FLINK=
-# Google Cloud project
-PROJECT=
-# Google Cloud zone
-ZONE=
-# Cloud commands
-GCLOUD=
-GSUTIL=
-```
-
-## Establish VM names for Flink master and workers
-
-```
-MASTER=flink-m
-NUM_WORKERS=5
-WORKERS=""
-for (( i = 0; i < $NUM_WORKERS; i++ )); do
-  WORKERS="$WORKERS flink-w-$i"
-done
-ALL="$MASTER $WORKERS"
-```
-
-## Build Beam
-
-```
-( cd $BEAM && mvn clean install )
-```
-
-## Bring up the cluster
-
-Establish project defaults and authenticate:
-```
-$GCLOUD init
-$GCLOUD auth login
-```
-
-Build Google Cloud Dataproc cluster:
-```
-$GCLOUD beta dataproc clusters create \
-  --project=$PROJECT \
-  --zone=$ZONE \
-  --bucket=nexmark \
-  --scopes=cloud-platform \
-  --num-workers=$NUM_WORKERS \
-  --image-version=preview \
-  flink
-```
-
-Force google_compute_engine ssh keys to be generated locally:
-```
-$GCLOUD compute ssh \
-  --project=$PROJECT \
-  --zone=$ZONE \
-  $MASTER \
-  --command 'exit'
-```
-
-Open ports on the VMs:
-```
-$GCLOUD compute firewall-rules create allow-monitoring --allow tcp:8080-8081
-$GCLOUD compute firewall-rules create allow-debug --allow tcp:5555
-```
-
-Establish keys on master and workers
-**CAUTION:** This will leave your private key on your master VM.
-Better would be to create a key just for inter-worker ssh.
-```
-for m in $ALL; do
-  echo "*** $m ***"
-  $GCLOUD beta compute scp \
-    --project=$PROJECT \
-    --zone=$ZONE \
-    ~/.ssh/google_compute_engine.pub $m:~/.ssh/
-done
-$GCLOUD beta compute scp \
-  --project=$PROJECT \
-  --zone=$ZONE \
-  ~/.ssh/google_compute_engine $MASTER:~/.ssh/
-```
-
-Collect IP addresses for workers:
-```
-MASTER_EXT_IP=$($GCLOUD compute instances describe \
- --project=$PROJECT \
-  --zone=$ZONE \
-  $MASTER | grep natIP: | sed 's/[ ]*natIP:[ ]*//')
-MASTER_IP=$($GCLOUD compute instances describe \
- --project=$PROJECT \
-  --zone=$ZONE \
-  $MASTER | grep networkIP: | sed 's/[ ]*networkIP:[ ]*//')
-WORKER_IPS=""
-for m in $WORKERS; do
-  echo "*** $m ***"
-  WORKER_IP=$($GCLOUD compute instances describe \
-    --project=$PROJECT \
-    --zone=$ZONE \
-    $m | grep networkIP: | sed 's/[ ]*networkIP:[ ]*//')
-  WORKER_IPS="$WORKER_IPS $WORKER_IP"
-done
-```
-
-Configure Flink:
-```
-cat $FLINK/conf/flink-conf.yaml \
-  | sed "s|.*\(jobmanager.rpc.address\):.*|\1: $MASTER_IP|g" \
-  | sed "s|.*\(jobmanager.heap.mb\):.*|\1: 4096|g" \
-  | sed "s|.*\(taskmanager.heap.mb\):.*|\1: 8192|g" \
-  | sed "s|.*\(parallelism.default\):.*|\1: $(($NUM_WORKERS * 4))|g" \
-  | sed "s|.*\(fs.hdfs.hadoopconf\):.*|\1: /etc/hadoop/conf|g" \
-  | sed "s|.*\(taskmanager.numberOfTaskSlots\):.*|\1: 4|g" \
-  | sed "s|.*\(jobmanager.web.submit.enable\):.*|\1: false|g" \
-  | sed "s|.*\(env.ssh.opts\):.*||g" \
-  > ~/flink-conf.yaml
-cat $FLINK/conf/log4j.properties \
-  | sed "s|.*\(log4j.rootLogger\)=.*|\1=ERROR, file|g" \
-  > ~/log4j.properties
-echo "env.ssh.opts: -i /home/$USER/.ssh/google_compute_engine -o StrictHostKeyChecking=no" >> ~/flink-conf.yaml
-echo "$MASTER_IP:8081" > ~/masters
-echo -n > ~/slaves
-for ip in $WORKER_IPS; do
-  echo $ip >> ~/slaves
-done
-cp -f \
-  ~/flink-conf.yaml \
-  ~/masters ~/slaves \
-  ~/log4j.properties \
-  $FLINK/conf/
-```
-
-Package configured Flink for distribution to workers:
-```
-( cd ~/ && tar -cvzf ~/flink.tgz $FLINK/* )
-```
-
-Distribute:
-```
-$GSUTIL cp ~/flink.tgz gs://nexmark
-for m in $ALL; do
-  echo "*** $m ***"
-  $GCLOUD compute ssh \
-    --project=$PROJECT \
-    --zone=$ZONE \
-    $m \
-    --command 'gsutil cp gs://nexmark/flink.tgz ~/ && tar -xvzf ~/flink.tgz'
-done
-```
-
-Start the Flink cluster:
-```
-$GCLOUD compute ssh \
-  --project=$PROJECT \
-  --zone=$ZONE \
-  $MASTER \
-  --command "~/$FLINK_VER/bin/start-cluster.sh"
-```
-
-Bring up the Flink monitoring UI:
-```
-/usr/bin/google-chrome $MASTER_EXT_IP:8081 &
-```
-
-## Run NexMark
-
-Distribute the Beam + NexMark jar to all workers:
-```
-$GSUTIL cp $BEAM/integration/java/target/java-integration-all-bundled-0.2.0-incubating-SNAPSHOT.jar gs://nexmark
-for m in $ALL; do
-  echo "*** $m ***"
-  $GCLOUD compute ssh \
-    --project=$PROJECT \
-    --zone=$ZONE \
-    $m \
-    --command "gsutil cp gs://nexmark/java-integration-all-bundled-0.2.0-incubating-SNAPSHOT.jar ~/$FLINK_VER/lib/"
-done
-```
-
-Create a Pubsub topic and subscription for testing:
-```
-$GCLOUD alpha pubsub \
-  --project=$PROJECT \
-  topics create flink_test
-
-$GCLOUD alpha pubsub \
-  --project=$PROJECT \
-  subscriptions create flink_test \
-  --topic flink_test \
-  --ack-deadline=60 \
-  --topic-project=$PROJECT
-```
-
-Launch!
-**NOTE:** As of flink-1.0.3 this will throw a `NullPointerException`
-in `org.apache.beam.sdk.io.PubsubUnboundedSink$WriterFn.startBundle`.
-See Jira issue [BEAM-196](https://issues.apache.org/jira/browse/BEAM-196).

+"""Fourth in a series of four pipelines that tell a story in a 'gaming' domain.
+
+New concepts: session windows and finding session duration; use of both
+singleton and non-singleton side inputs.
+
+This pipeline builds on the {@link LeaderBoard} functionality, and adds some
+"business intelligence" analysis: abuse detection and usage patterns. The
+pipeline derives the Mean user score sum for a window, and uses that information
+to identify likely spammers/robots. (The robots have a higher click rate than
+the human users). The 'robot' users are then filtered out when calculating the
+team scores.
+
+Additionally, user sessions are tracked: that is, we find bursts of user
+activity using session windows. Then, the mean session duration information is
+recorded in the context of subsequent fixed windowing. (This could be used to
+tell us what games are giving us greater user retention).
+
+Run injector.Injector to generate pubsub data for this pipeline. The Injector
+documentation provides more detail on how to do this. The injector is currently
+implemented in Java only, it can be used from the Java SDK.
+
+The PubSub topic you specify should be the same topic to which the Injector is
+publishing.
+
+To run the Java injector:
+/examples/java8$ mvn compile exec:java \
+    -Dexec.mainClass=org.apache.beam.examples.complete.game.injector.Injector \
+    -Dexec.args="$PROJECT_ID $PUBSUB_TOPIC none"
+
+For a description of the usage and options, use -h or --help.
+
+To specify a different runner:
+  --runner YOUR_RUNNER
+
+NOTE: When specifying a different runner, additional runner-specific options
+      may have to be passed in as well
+

+"""Third in a series of four pipelines that tell a story in a 'gaming' domain.
+
+Concepts include: processing unbounded data using fixed windows; use of custom
+timestamps and event-time processing; generation of early/speculative results;
+using AccumulationMode.ACCUMULATING to do cumulative processing of late-arriving
+data.
+
+This pipeline processes an unbounded stream of 'game events'. The calculation of
+the team scores uses fixed windowing based on event time (the time of the game
+play event), not processing time (the time that an event is processed by the
+pipeline). The pipeline calculates the sum of scores per team, for each window.
+By default, the team scores are calculated using one-hour windows.
+
+In contrast-- to demo another windowing option-- the user scores are calculated
+using a global window, which periodically (every ten minutes) emits cumulative
+user score sums.
+
+In contrast to the previous pipelines in the series, which used static, finite
+input data, here we're using an unbounded data source, which lets us provide
+speculative results, and allows handling of late data, at much lower latency.
+We can use the early/speculative results to keep a 'leaderboard' updated in
+near-realtime. Our handling of late data lets us generate correct results,
+e.g. for 'team prizes'. We're now outputting window results as they're
+calculated, giving us much lower latency than with the previous batch examples.
+
+Run injector.Injector to generate pubsub data for this pipeline. The Injector
+documentation provides more detail on how to do this. The injector is currently
+implemented in Java only, it can be used from the Java SDK.
+
+The PubSub topic you specify should be the same topic to which the Injector is
+publishing.
+
+To run the Java injector:
+/examples/java8$ mvn compile exec:java \
+    -Dexec.mainClass=org.apache.beam.examples.complete.game.injector.Injector \
+    -Dexec.args="$PROJECT_ID $PUBSUB_TOPIC none"
+
+For a description of the usage and options, use -h or --help.
+
+To specify a different runner:
+  --runner YOUR_RUNNER
+
+NOTE: When specifying a different runner, additional runner-specific options
+      may have to be passed in as well
+

Subject: [PATCH 068/578] [BEAM-1347] Provide an abstraction which creates an
 Iterator view over the Beam Fn State API

Combining this with the DataStreams.DataStreamDecoder converts the Beam Fn State API into a
an input stream backed by multiple logical chunks.

+ * requested, this input source will wait until the time of the batch which set the watermark has
+ * caught up and the following holds:
+ *
+ * {@code
+ * CURRENT_BATCH_TIME - TIME_OF_BATCH_WHICH_SET_THE_WATERMARK <= BATCH_DURATION
+ * }
+ *
+ * 
In other words, this input source will stall and will NOT generate RDDs when the watermark is
+ * too far behind. Once the watermark has caught up with the current batch time, an RDD will be
+ * generated and emitted downstream.
+ *
+ * 
NOTE: This input source is intended for test-use only, where one needs to be able to simulate
+ * non-trivial scenarios under a deterministic execution even at the cost incorporating test-only
+ * code. Unlike tests, in production InputDStreams will not be synchronous with the
+ * watermark, and the watermark is allowed to lag behind in a non-deterministic manner (since at
+ * this point in time we are reluctant to apply complex and possibly overly synchronous mechanisms
+ * at large scale).

Subject: [PATCH 116/578] Moves Match into FileIO.match()/matchAll()

FileIO will later gain other methods, such as read()/write().

Also introduces FileIO.MatchConfiguration - a common type to use
by various file-based IOs to reduce boilerplate, and uses it in TextIO.

Subject: [PATCH 122/578] FnApiControlClient, de-inverts Fn API control plane

The Fn API control plane has an inverted client/server relationship in
order to support firewall rules where the runner is forbidden from
connecting out to the SDK harness. This Java helper provides an API with
the more conventional polarity. It also associates streamed gRPC
requests with responses to support simple future-based programming.

Subject: [PATCH 124/578] Higher-level SdkHarnessClient

This adds a fairly thin wrapper on FnApiSdkHarnessClient, encapsulating
the fact that all request and response types are injected into a
disjoint union and sent over the same low-level RPC.

Subject: [PATCH 125/578] Add SdkHarnessDoFnRunner

This encapsulates processing a bundle over the Fn API.

A Beam runner is responsible for:

 - Setting up a FnApiControlClientPoolService to listen for incoming
   FnApiSdkHarnessClient connections
 - Wrapping those connections in the higher-level SdkHarnessClient
 - Building the ProcessBundleDescriptor (instruction graph) to be executed
 - Establishing data plane endpoints referenced by the ProcessBundleDescriptor
 - Registering the data plane endpoints and ProcessBundleDescriptor with the
   SdkHarnessClient

This class is responsible for:

 - Registering each bundle with the SDK harness
 - Streaming the elements of each bundle to the SDK harness
   over the data plane

Subject: [PATCH 127/578] Ignore HTTP 404 when deleting GCS files

You can get a 404 if a previous delete RPC actually succeeded
but returned a failed response due to some network issues,
so the next attempt gets a 404.

Before start, follow https://kafka.apache.org/quickstart to setup a Kafka

+ * 
+ * 
+ * bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 1 \
+ *   --partitions 1 --topic orders
+ * bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 1 \
+ *   --partitions 1 --topic sub_orders
+ * 
+ * 

+ * After run the application, produce several test records:
+ * 
+ * 
+ * bin/kafka-console-producer.sh --broker-list localhost:9092 --topic orders
+ * invalid,record
+ * 123445,0,100,3413423

+ * 345234,0,345234.345,3423
+ * 
+ * 

+ * Meanwhile, open another console to see the output:
+ * 
+ * 
+ * bin/kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic sub_orders
+ * **Expected :
+ * 123445,0,100.0

Subject: [PATCH 160/578] [BEAM-2149] Improved kafka table implemention.

1. use robust CSV library to parse & print.
2. support different data types rather than just `String`.
3. a little cleanup for TextTable (to extract common methods).

+/**
+ * {@code BeamRelNode} to replace a {@code Sort} node.

+ * 
Since Beam does not fully supported global sort we are using {@link Top} to implement
+ * the {@code Sort} algebra. The following types of ORDER BY are supported:
+
+ * 
{@code
+ *     select * from t order by id desc limit 10;
+ *     select * from t order by id desc limit 10, 5;

+ *
+ * 
but Order BY without a limit is NOT supported:
+ *
+ * 
{@code
+ *   select * from t order by id desc
+ * }

+ *
+ * 
Constraints

+ * 
    
+ *   
  • Due to the constraints of {@link Top}, the result of a `ORDER BY LIMIT`
+ *   must fit into the memory of a single machine.
    • 
+ *   
  • Since `WINDOW`(HOP, TUMBLE, SESSION etc) is always associated with `GroupBy`,
+ *   it does not make much sense to use `ORDER BY` with `WINDOW`.

-/**
- * {@code BeamSQLEnvironment} is the integrated environment of BeamSQL.
- * It provides runtime context to execute SQL queries as Beam pipeline,
- * including table metadata, SQL engine and a Beam pipeline translator.
- *
- * 
1. BeamSQL as DSL

- * BeamSQL as DSL enables developers to embed SQL queries when writing a Beam pipeline.
- * A typical pipeline with BeamSQL DSL is:
- * 
- *{@code
-PipelineOptions options =  PipelineOptionsFactory...
-Pipeline pipeline = Pipeline.create(options);
-
-//prepare environment of BeamSQL
-BeamSQLEnvironment sqlEnv = BeamSQLEnvironment.create();
-//register table metadata
-sqlEnv.addTableMetadata(String tableName, BeamSqlTable tableMetadata);
-//register UDF
-sqlEnv.registerUDF(String functionName, Method udfMethod);
-
-
-//explain a SQL statement, SELECT only, and return as a PCollection;
-PCollection phase1Stream = sqlEnv.explainSQL(pipeline, String sqlStatement);
-//A PCollection explained by BeamSQL can be converted into a table, and apply queries on it;
-sqlEnv.registerPCollectionAsTable(String tableName, phase1Stream);
-
-//apply more queries, even based on phase1Stream
-
-pipeline.run().waitUntilFinish();
- * }
- * 

- *
- * 
2. BeamSQL as CLI

- * This feature is on planning, and not ready yet.

Subject: [PATCH 179/578] [BEAM-2442] BeamSql surface api test.

The surface api of BeamSql includes the following:
- BeamSql
- BeamSqlCli
- BeamSqlEnv
- All the classes in package org.apache.beam.dsls.sql.schema

Calcite related methods are encapsulated into CalciteUtils(which is not part of surface api) to avoid exposure.

Created a new BeamSqlTable interface which abstracts the beam table concept.

RelDataType, RelProtoDataType are all removed from surface api, BeamSqlRecordType is the only class which represents the schema of a table.
java.sql.Types is used to represent sql type instead of Calcite SqlTypeName.

Subject: [PATCH 190/578] [BEAM-2193] Implement FULL, INNER, and OUTER JOIN: -
 FULL and INNER supported on all variations of unbounded/bounded joins. -
 OUTER JOIN supported when outer side is unbounded. - Unbounded/bounded joins
 implemented via side inputs.

+/**
+ * {@code BeamRelNode} to replace a {@code Join} node.
+ *
+ * 
Support for join can be categorized into 3 cases:
+ * 
    
+ *   
  • BoundedTable JOIN BoundedTable
    • 
+ *   
  • UnboundedTable JOIN UnboundedTable
    • 
+ *   
  • BoundedTable JOIN UnboundedTable
    • 
+ * 

+ *
+ * 
For the first two cases, a standard join is utilized as long as the windowFn of the both
+ * sides match.
+ *
+ * 
For the third case, {@code sideInput} is utilized to implement the join, so there are some
+ * constraints:
+ *
+ * 
    
+ *   
  • {@code FULL OUTER JOIN} is not supported.
    • 
+ *   
  • If it's a {@code LEFT OUTER JOIN}, the unbounded table should on the left side.
    • 
+ *   
  • If it's a {@code RIGHT OUTER JOIN}, the unbounded table should on the right side.
    • 
+ * 

+ *
+ *
+ * 
There are also some general constraints:
+ *
+ * 
    
+ *  
  • Only equi-join is supported.
    • 
+ *  
  • CROSS JOIN is not supported.
    • 
+ *

Subject: [PATCH 240/578] var_pop and var_samp

two builtin aggregation functions

fix checkstyle

address comments

change type of sum in class VarAgg to BigDecimal
move isSamp field to Var
rename VarPop -> Var to make more generic
move logic to prepareOutput() both for Avg and Var
set MathContext to handle potential exception with BigDecimal divide.

newlines

rebase issue

assertEquals to test with delta

Subject: [PATCH 269/578] [BEAM-2957] Fix flaky ElasticsearchIOTest.testSplit
 in beam-sdks-java-io-elasticsearch-tests-5

ES Slices are based on document id. For them to be deterministic (no empty slice), ids need to be always the same.
Provide document id at insertion time rather than letting Elasticsearch generate one.
Fix assert message in testSplit

Unrelated:
Update ES rest client from 5.0 to 5.4
Remove unneeded jna version property

Subject: [PATCH 271/578] Move DoFnInfo to SDK util

Previously, the DoFnInfo wrapped things just enough for Dataflow to execute a
DoFn without much context. The Java SDK harness has the same need, and relies
on DoFnInfo. Effectively, DoFnInfo is the UDF that the Java SDK harness
understands.

Subject: [PATCH 283/578] Updates grpc-google-pubsub-v1 to
 grpc-google-cloud-pubsub-v1

This is good because it's a newer version, and because it gets
rid of a dependency conflict with Spanner.

Subject: [PATCH 303/578] Revert "This closes #3859: [BEAM-2884] Send portable
 protos for ParDo in DataflowRunner"

This reverts commit 0d5d00d7060d6e4ee8273201e3432f14abf35f8a, reversing
changes made to 4e4d102124576aefc3f71e432dbf6197aaaa92e3.

The blowup to the job submission was a bit much. We will instead wait to
implement a more robust longer-term solution that does not embed the protos
directly in the job submission.

+  Apache Beam :: Runners :: Java Local Artifact Service
+  The Beam Artifact Service exposes APIs to stage and retrieve
+    artifacts in a manner independent of the underlying storage system, for use
+    by the Beam portability framework. The local implementation uses the local
+    File System as the underlying storage system.

Subject: [PATCH 311/578] Updates WriteToBigQuery PTransform to get project id
 from GoogleCloudOptions when using DirectRunner.

WriteToBigQuery PTransform behaves differently for DirectRunner and DataflowRunner when it comes to determining the project that the output table belongs to. If a project is not specified, DataflowRunner defauls to GoogleCloudOptions.project while DirectRunner does not. This PR fixes this inconsistency by defaulting to GoogleCloudOptions.project for DirectRunner as well.

Subject: [PATCH 312/578] Use the SubscriptionProvider in PubsubUnboundedSource

During expansion, a ValueProvider may not be accessible. This ensures
that if the subscription is based on a value provider, it will only be
evaluated when that ValueProvider is bound, rather than at construction
time.

Subject: [PATCH 322/578] Sets a TTL on BigQueryIO.read().fromQuery() temp
 dataset

Also fixes a bug where we start the query job twice -
once to extract the files, once to get schema. Luckily it doesn't
actually run twice, because inserting the same job a second time gives
an ignorable error, but it was still icky.

Also adds some logging.

    The following is the relationship between BigQuery schema and Java types:
-   *
-   * 
      
-   *   
    • Nulls are {@code null}.
-   *   
    • Repeated fields are {@code List} of objects.
-   *   
    • Record columns are {@link TableRow} objects.
-   *   
    • {@code BOOLEAN} columns are JSON booleans, hence Java {@code Boolean} objects.
-   *   
    • {@code FLOAT} columns are JSON floats, hence Java {@code Double} objects.
-   *   
    • {@code TIMESTAMP} columns are {@code String} objects that are of the format
-   *       {@code yyyy-MM-dd HH:mm:ss[.SSSSSS] UTC}, where the {@code .SSSSSS} has no trailing
-   *       zeros and can be 1 to 6 digits long.
-   *   
    • Every other atomic type is a {@code String}.
-   * 
    
-   *
-   * 
    Note that integers are encoded as strings to match BigQuery's exported JSON format.
-   *

Subject: [PATCH 325/578] PAssert improvements.

- Captures stack trace by introducing a SerializableThrowable.
  Fixes an incorrect test of this.
- PAssert.thatSingletonIterable, thatMap/Multimap/Singleton no longer
  require that the collection is produced by a trigger that promises
  a single firing. thatSingletonIterable checks that the iterable is a
  singleton by other means. thatMap/Multimap/Singleton don't need this
  requirement at all.
  PaneExtractors.onlyPane() is now used only when the user explicitly
  specifies inOnlyPane().

Subject: [PATCH 326/578] Introduces Reshuffle.viaRandomKey()

It's a commonly used pattern for breaking fusion
https://cloud.google.com/dataflow/service/dataflow-service-desc#fusion-optimization

viaRandomKey() only abstracts away the current commonly used pattern.
It has the same caveats as using Reshuffle.of() directly - the semantics
are technically not guaranteed by the Beam model, but it works in
practice, and this is the pattern we keep recommending to users.

The naming is deliberately operational rather than semantic, to
emphasize that we don't have the semantics figured out, and the
transform promises only that it expands into exactly the sequence
"pair with random key, reshuffle, drop key".
The goal of this change is just to reduce copy-paste.

See prior discussion at
https://lists.apache.org/thread.html/ac34c9ac665a8d9f67b0254015e44c59ea65ecc1360d4014b95d3b2e@%3Cdev.beam.apache.org%3E

This change also converts several existing usages to use it, and adds another
one in Match.

    Reading
    
  *
- * 
    To read from a BigQuery table, apply a {@link BigQueryIO.Read} transformation. This produces a
- * {@link PCollection} of {@link TableRow TableRows} as output:
+ * 
    Reading from BigQuery is supported by {@link #read(SerializableFunction)}, which parses
+ * records in AVRO format
+ * into a custom type using a specified parse function, and by {@link #readTableRows} which parses
+ * them into {@link TableRow}, which may be more convenient but has lower performance.
  *
+ * 
    Both functions support reading either from a table or from the result of a query, via
+ * {@link TypedRead#from(String)} and {@link TypedRead#fromQuery} respectively. Exactly one
+ * of these must be specified.
+ *
+ * Example: Reading rows of a table as {@link TableRow}.
  * 
    {@code
  * PCollection weatherData = pipeline.apply(
- *     BigQueryIO.read().from("clouddataflow-readonly:samples.weather_stations"));
+ *     BigQueryIO.readTableRows().from("clouddataflow-readonly:samples.weather_stations"));
  * }
    
  *
- * 
    See {@link TableRow} for more information on the {@link TableRow} object.
+ * Example: Reading rows of a table and parsing them into a custom type.
+ * 
    {@code
+ * PCollection weatherData = pipeline.apply(
+ *    BigQueryIO
+ *      .read(new SerializableFunction() {
+ *        public WeatherRecord apply(SchemaAndRecord schemaAndRecord) {
+ *          return new WeatherRecord(...);
+ *        }
+ *      })
+ *      .from("clouddataflow-readonly:samples.weather_stations"))
+ *      .withCoder(SerializableCoder.of(WeatherRecord.class));
+ * }
    
  *
- * 
    Users may provide a query to read from rather than reading all of a BigQuery table. If
- * specified, the result obtained by executing the specified query will be used as the data of the
- * input transform.
+ * 
    Note: When using {@link #read(SerializableFunction)}, you may sometimes need to use
+ * {@link TypedRead#withCoder(Coder)} to specify a {@link Coder} for the result type, if Beam
+ * fails to infer it automatically.
  *
+ * Example: Reading results of a query as {@link TableRow}.
  * 
    {@code
- * PCollection meanTemperatureData = pipeline.apply(
- *     BigQueryIO.read().fromQuery("SELECT year, mean_temp FROM [samples.weather_stations]"));
+ * PCollection meanTemperatureData = pipeline.apply(BigQueryIO.readTableRows()
+ *     .fromQuery("SELECT year, mean_temp FROM [samples.weather_stations]"));
  * }
    
  *
- * 
    When creating a BigQuery input transform, users should provide either a query or a table.
- * Pipeline construction will fail with a validation error if neither or both are specified.

Subject: [PATCH 363/578] Adds API for defining Splittable DoFns.

See https://s.apache.org/splittable-do-fn-python-sdk for the design.

This PR and the above doc were updated to reflect following recent updates to Splittable DoFn.
* Support for ProcessContinuations
* Support for dynamically updating output watermark irrespective of the output element production.

This will be followed by a PR that adds support for reading Splittable DoFns using DirectRunner.

Subject: [PATCH 367/578] [BEAM-2877][BEAM-2881] Add Java SDK harness container
 image and support

 * Add support for building Go code and docker container images with
   maven (see sdks/go/BUILD.md for details). The latter is only done
   if the "build-containers" profile is used.
 * Add GCS proxy service for managing artifacts in GCS.
 * Add GCE md service for metdata-configured provision info in GCE.
 * Add beamctl tool for manually interacting with these services.

This PR is focused on the execution side and would need support from
the submission side as well to be functional. The ULR will likely be
the first runner to tie everything together. The contents of the java
image is kept simple for now.

+# Go build
+
+This document describes the [Go](golang.org) code layout and build integration
+with Maven. The setup is non-trivial, because the Go toolchain expects a
+certain layout and Maven support is limited.
+
+Goals:
+
+ 1. Go code can be built and tested using Maven w/o special requirements.
+ 1. Go tools such as `go build`, `go test` and `go generate` work as usual.
+ 1. Go code can be pulled with `go get` from `github.com/apache/beam` for users.
+ 1. Go programs can used in docker container images.
+
+In short, the goals are to make both worlds work well.
+
+### Maven integration
+
+The Go toolchain expects the package name to match the directory structure,
+which in turn must be rooted in `github.com/apache/beam` for `go get` to work.
+This directory prefix is beyond the repo itself and we must copy the Go source
+code into such a layout to invoke the tool chain. We use a single directory
+`sdks/go` for all shared library code and export it as a zip file during the 
+build process to be used by various tools, such as `sdks/java/container`.
+This scheme balances the convenience of combined Go setup with the desire
+for a unified layout across languages. Python seems to do the same.
+
+The container build adds a small twist to the build integration, because
+container images use linux/amd64 but the development setup might not. We
+therefore additionally cross-compile Go binaries for inclusion into container
+images where needed, generally placed in `target/linux_amd64`.
+
+### Go development setup
+
+Developers must clone their git repository into:
+```
+$GOPATH/src/github.com/apache
+
+```
+to match the package structure expected by the code imports. Go users can just
+`go get` the code directly. For example:
+```
+go get github.com/apache/beam/sdks/go/...
+```
+Developers must invoke Go for cross-compilation manually, if desired.

+ * lexicographically compared to yield the same comparison value that
+ * would have been generated if the encoded items had been compared
+ * one by one according to their type.
+ *
+ * 
      More precisely, suppose:
+ *  1. byte array A is generated by encoding the sequence of items [A_1..A_n]
+ *  2. byte array B is generated by encoding the sequence of items [B_1..B_n]
+ *  3. The types match; i.e., for all i: A_i was encoded using
+ *     the same routine as B_i
+ *
+ * 
      Then:
+ *    Comparing A vs. B lexicographically is the same as comparing
+ *    the vectors [A_1..A_n] and [B_1..B_n] lexicographically.
+ *
+ * 
      This class is NOT thread safe.

Subject: [PATCH 385/578] Fixes TextIO and AvroIO tests of watchForNewFiles

* AvroIO: Need to specify a trigger to make sure that files are really
generated continuously and testing of watchForNewFiles is non-vacuous.

* TextIO: files were generated by manual code,
and sometimes writing of a file could race with TextIO reading it, and
it might see the same file with two different sizes, and count it as two
different files (two Metadata objects for the same filename with
different sizes are not equal) and read the file twice.

It makes sense to address that separately: e.g. in the Watch transform
allow specifying a key extractor - but it's outside the scope of this
PR.

 interfaces

By adding the @FunctionalInterface to RowMapper, StatementPreperator and
PreparedStatementSetter it's possible to write a JdbcIO source in a
more concise and functional style.

This change is backwards compatible with existing JdbcIO sources.

Subject: [PATCH 397/578] Revert "Use de(stributed)tox rather than plain old
 tox for Python testing."

This reverts commit 9052a16a66e71f5c738ee148c81bc3e848a2cabe.

Switch back to using tox. We suspect that detox is causing test
stuckness, also cython related tests are not properly isolated with tox
(or detox), it results in problem with multiple test environments are
executed in parallel.

+# Docker containers
+
+The Beam [portability effort](https://s.apache.org/beam-fn-api) aims to make it possible
+for any SDK to work with any runner. One aspect of the effort is the isolation of the SDK
+and user code execution environment from the runner execution environment using
+[docker](https://www.docker.com/), as defined in the portability
+[container contract](https://s.apache.org/beam-fn-api-container-contract).
+
+This document describes how to build and push container images to that end. The push
+step generally requires an account with a public docker registry, such
+as [bintray.io](bintray.io) or
+[Google Container Registry](https://cloud.google.com/container-registry). These
+instructions assume familiarity with docker and a bintray account under the
+current username with a docker repository named "apache".
+
+## How to build container images
+
+**Prerequisites**: install [docker](https://www.docker.com/) on your
+platform. You can verify that it works by running `docker images` or any other
+docker command.
+
+Run Maven with the `build-containers` profile:
+
+```
+$ pwd
+[...]/beam
+$ mvn clean install -DskipTests -Pbuild-containers
+[...]
+[INFO] --- dockerfile-maven-plugin:1.3.5:build (default) @ beam-sdks-python-container ---
+[INFO] Using Google application default credentials
+[INFO] loaded credentials for user account with clientId=[...].apps.googleusercontent.com
+[INFO] Building Docker context /Users/herohde/go/src/github.com/apache/beam/sdks/python/container
+[INFO]

+[INFO] Status: Image is up to date for python:2

+[INFO] Successfully built herohde-docker-apache.bintray.io/beam/python:latest
+[INFO]
+[...]
+```
+
+Note that the container images include built content, including the Go boot
+code, so you should build from the top level directory unless you're familiar
+with Maven.
+
+**(Optional)** When built, you can see, inspect and run them locally:
+
+```
+$ docker images
+REPOSITORY                                       TAG                    IMAGE ID            CREATED             SIZE
+herohde-docker-apache.bintray.io/beam/python     latest                 c8bf712741c8        About an hour ago   690MB
+herohde-docker-apache.bintray.io/beam/java       latest                 33efc0947952        About an hour ago   773MB
+[...]
+```
+
+Despite the names, these container images live only on your local machine.
+While we will re-use the same tag "latest" for each build, the
+images IDs will change.
+
+**(Optional)**: the default setting for `docker-repository-root` specifies the above bintray
+location. You can override it by adding: 
+
+```
+-Ddocker-repository-root=
+```
+
+Similarly, if you want to specify a specific tag instead of "latest", such as a "2.3.0"
+version, you can do so by adding:
+
+```
+-Ddockerfile.tag=
+```
+
+## How to push container images
+
+**Preprequisites**: obtain a docker registry account and ensure docker can push images to it,
+usually by doing `docker login` with the appropriate information. The image you want
+to push must also be present in the local docker image repository.
+
+For the Python SDK harness container image, run:
+
+```
+$ docker push $USER-docker-apache.bintray.io/beam/python:latest
+The push refers to a repository [herohde-docker-apache.bintray.io/beam/python]

+
+```
+
+Similarly for the Java SDK harness container image. If you want to push the same image
+to multiple registries, you can retagging the image using `docker tag` and push.
+
+**(Optional)** On any machine, you can now pull the pushed container image:
+
+```
+$ docker pull $USER-docker-apache.bintray.io/beam/python:latest
+latest: Pulling from beam/python
+85b1f47fba49: Pull complete

+
+Note that the image IDs and digests match their local counterparts.

Subject: [PATCH 418/578] Add futurize to pylint script

Break down futurize pylint

Fix the pylint script checking futurize

Consists of:

Quote the futurize options shell scripting

Jenkins seems to be having weird behaviour with futurize_filtered=, temporary debugging commit

Try quoting the count line.

Do the style fixes from shellcheck on pylint, parallilize futurize command & simplify the grep on output

Fall through on grep exit code of 1 which happens when everything is filtered out & change count check to 0

Remove some debugging from pylint

+ * 
          Usage with templates
          
+ *
+ * 
          When using {@link #read} or {@link #readTableRows()} in a template, it's required to specify
+ * {@link Read#withTemplateCompatibility()}. Specifying this in a non-template pipeline is not
+ * recommended because it has somewhat lower performance.
+ *
+ * 
          When using {@link #write()} or {@link #writeTableRows()} with batch loads in a template, it is
+ * recommended to specify {@link Write#withCustomGcsTempLocation}. Writing to BigQuery via batch
+ * loads involves writing temporary files to this location, so the location must be accessible at
+ * pipeline execution time. By default, this location is captured at pipeline construction
+ * time, may be inaccessible if the template may be reused from a different project or at a moment
+ * when the original location no longer exists.
+ * {@link Write#withCustomGcsTempLocation(ValueProvider)} allows specifying the location as an
+ * argument to the template invocation.
+ *
+ * 
          Permissions
          
+ *
+ * 
          Permission requirements depend on the {@link PipelineRunner} that is used to execute the
+ * pipeline. Please refer to the documentation of corresponding {@link PipelineRunner}s for more
+ * details.
+ *
+ * 
          Please see BigQuery Access Control
+ *  for security and permission related information specific to BigQuery.

Subject: [PATCH 449/578] [BEAM-1487, BEAM-3016] Address termination
 correctness issues in BufferingStreamObserver & BeamFnLoggingClient

The issue with BeamFnLoggingClient is that we can't arriveAndDeregister during termination since
the onReadyHandler may also arrive at the same time which is why we swap to using forced termination.
Also, I added code that would guarantee that log messages produced by the thread which is shutting
down are guaranteed to make it (this was being caught occassionally by the testLogging test).

The BufferingStreamObserver was incorrectly shutting down since it may attempt to enqueue something
into a full queue with a reading thread that has already exitted for some reason so it would loop
forever attempting to insert the poison pill.

          Reading Redis key/value pairs
          
+ *
+ * 
          {@link #read()} provides a source which returns a bounded {@link PCollection} containing
+ * key/value pairs as {@code KV}.
+ *
+ * 
          To configure a Redis source, you have to provide Redis server hostname and port number.
+ * Optionally, you can provide a key pattern (to filter the keys). The following example
+ * illustrates how to configure a source:
+ *
+ * 
          {@code
+ *
+ *  pipeline.apply(RedisIO.read()
+ *    .withEndpoint("::1", 6379)
+ *    .withKeyPattern("foo*"))
+ *
+ * }
          
+ *
+ * 
          It's also possible to specify Redis authentication and connection timeout with the
+ * corresponding methods:
+ *
+ * 
          {@code
+ *
+ *  pipeline.apply(RedisIO.read()
+ *    .withEndpoint("::1", 6379)
+ *    .withAuth("authPassword")
+ *    .withTimeout(60000)
+ *    .withKeyPattern("foo*"))
+ *
+ * }
          
+ *
+ * 
          {@link #readAll()} can be used to request Redis server using input PCollection elements as key
+ * pattern (as String).
+ *
+ * 
          {@code
+ *
+ *  pipeline.apply(...)
+ *     // here we have a PCollection with the key patterns
+ *     .apply(RedisIO.readAll().withEndpoint("::1", 6379))
+ *    // here we have a PCollection>
+ *
+ * }
          
+ *
+ * 
          Writing Redis key/value pairs
          
+ *
+ * 
          {@link #write()} provides a sink to write key/value pairs represented as
+ * {@link KV} from an incoming {@link PCollection}.
+ *
+ * 
          To configure the target Redis server, you have to provide Redis server hostname and port
+ * number. The following example illustrates how to configure a sink:
+ *
+ * 
          {@code
+ *
+ *  pipeline.apply(...)
+ *    // here we a have a PCollection with key/value pairs
+ *    .apply(RedisIO.write().withEndpoint("::1", 6379))
+ *
+ * }

+    // across a fixed number of shards and records in each shard are written in order. It drops
+    // any records that are already written and buffers those arriving out of order.
+    //
+    //  // Exactly once sink involves two shuffles of the records:
+    //            A -- GBK --> B -- GBK --> C
+    //
+    // Processing guarantees also require deterministic processing within user transforms.
+    // in this case that implies the order of the records seen by C should not be affected by
+    // restarts in upstream stages link B & A.
+    //
+    // A : Assigns a random shard for message. Note that there are no ordering guarantees for
+    //     writing user records to Kafka. User can still control partitioning among topic
+    //     partitions as with regular sink (of course, there are no ordering guarantees in
+    //     regular Kafka sink either).
+    // B : Assigns an id sequentially for each messages within a shard.
+    // C : Writes each shard to Kafka in sequential id order. In Dataflow, when C sees a record
+    //     and id, it implies that record and the associated id are checkpointed to persistent
+    //     storage and this record will always have same id, even in retries.
+    //     Exactly-once semantics are achieved by writing records in the strict order of
+    //     these checkpointed sequence ids.
+    //
+    // Parallelism for B and C is fixed to 'numShards', which defaults to number of partitions
+    // for the topic. A few reasons for that:
+    //  - B & C implement their functionality using per-key state. Shard id makes it independent
+    //    of cardinality of user key.
+    //  - We create one producer per shard, and its 'transactional id' is based on shard id. This
+    //    requires that number of shards to be finite. This also helps with batching. and avoids
+    //    initializing producers and transactions.
+    //  - Most importantly, each of sharded writers stores 'next message id' in partition
+    //    metadata, which is committed atomically with Kafka transactions. This is critical
+    //    to handle retries of C correctly. Initial testing showed number of shards could be
+    //    larger than number of partitions for the topic.

+     * 
          Beam runners typically provide exactly-once semantics for results of a pipeline, but not
+     * for side effects from user code in transform.  If a transform such as Kafka sink writes
+     * to an external system, those writes might occur more than once. When EOS is enabled here,
+     * the sink transform ties checkpointing semantics in compatible Beam runners and transactions
+     * in Kafka (version 0.11+) to ensure a record is written only once. As the implementation
+     * relies on runners checkpoint semantics, not all the runners are compatible. The sink throws
+     * an exception during initialization if the runner is not whitelisted. Flink runner is
+     * one of the runners whose checkpoint semantics are not compatible with current
+     * implementation (hope to provide a solution in near future). Dataflow runner and Spark
+     * runners are whitelisted as compatible.

 /**
- * {@link PTransform} for parsing arbitrary files using Apache Tika.
+ * A collection of {@link PTransform} transforms for parsing arbitrary files using Apache Tika.
  * Files in many well known text, binary or scientific formats can be processed.
  *
- * 
          To read a {@link PCollection} from one or more files
- * use {@link TikaIO.Read#from(String)}
- * to specify the path of the file(s) to be read.
+ * 
          {@link TikaIO.Parse} and {@link TikaIO.ParseAll} parse the files and return
+ * a {@link PCollection} containing one {@link ParseResult} per each file.
+ *
+ * 
          Combine {@link TikaIO.ParseAll} with {@link FileIO.Match}
+ * and {@link FileIO.ReadMatches} to match, read and parse the files.
+ *
+ * 
          Example:
  *
- * 
          {@link TikaIO.Read} returns a bounded {@link PCollection} of {@link String Strings},
- * each corresponding to a sequence of characters reported by Apache Tika SAX Parser.
+ * 
          {@code
+ * Pipeline p = ...;
+ *
+ * // A simple parse of a local PDF file (only runs locally):
+ * PCollection results =
+ *   p.apply(FileIO.match().filepattern("/local/path/to/file.pdf"))
+ *    .apply(FileIO.readMatches())
+ *    .apply(TikaIO.parseFiles());
+ * }
          
+ *
+ * 
          Use {@link TikaIO.Parse} to match, read and parse the files in simple cases.
  *
  * 
          Example:
  *
  * 
          {@code
  * Pipeline p = ...;
  *
- * // A simple Read of a local PDF file (only runs locally):
- * PCollection content = p.apply(TikaInput.from("/local/path/to/file.pdf"));
+ * // A simple parse of a local PDF file (only runs locally):
+ * PCollection results =
+ *   p.apply(TikaIO.parseAll().filepattern("/local/path/to/file.pdf"));
  * }
          
  *
  * Warning: the API of this IO is likely to change in the next release.

 /**
- * A collection of {@link PTransform} transforms for parsing arbitrary files using Apache Tika.
- * Files in many well known text, binary or scientific formats can be processed.
+ * Transforms for parsing arbitrary files using Apache Tika.
+ *
+ * 
          Tika is able to extract text and metadata from files in many well known text, binary and
+ * scientific formats.
  *
- * 
          {@link TikaIO.Parse} and {@link TikaIO.ParseAll} parse the files and return
- * a {@link PCollection} containing one {@link ParseResult} per each file.
+ * 
          The entry points are {@link #parse} and {@link #parseFiles}. They parse a set of files and
+ * return a {@link PCollection} containing one {@link ParseResult} per each file. {@link #parse}
+ * implements the common case of parsing all files matching a single filepattern, while {@link
+ * #parseFiles} should be used for all use cases requiring more control, in combination with {@link
+ * FileIO#match} and {@link FileIO#readMatches} (see their respective documentation).
  *
- * 
          Combine {@link TikaIO.ParseAll} with {@link FileIO.Match}
- * and {@link FileIO.ReadMatches} to match, read and parse the files.
+ * 
          {@link #parse} does not automatically uncompress compressed files: they are passed to Tika
+ * as-is.
  *
- * 
          Example:
+ * 
          It's possible that some files will partially or completely fail to parse. In that case, the
+ * respective {@link ParseResult} will be marked unsuccessful (see {@link ParseResult#isSuccess})
+ * and will contain the error, available via {@link ParseResult#getError}.
+ *
+ * 
          Example: using {@link #parse} to parse all PDF files in a directory on GCS.
  *
  * 
          {@code
  * Pipeline p = ...;
  *
- * // A simple parse of a local PDF file (only runs locally):
  * PCollection results =
- *   p.apply(FileIO.match().filepattern("/local/path/to/file.pdf"))
- *    .apply(FileIO.readMatches())
- *    .apply(TikaIO.parseFiles());
+ *   p.apply(TikaIO.parse().filepattern("gs://my-bucket/files/*.pdf"));
  * }
          
  *
- * 
          Use {@link TikaIO.Parse} to match, read and parse the files in simple cases.
- *
- * 
          Example:
+ * 
          Example: using {@link #parseFiles} in combination with {@link FileIO} to continuously parse
+ * new PDF files arriving into the directory.
  *
  * 
          {@code
  * Pipeline p = ...;
  *
- * // A simple parse of a local PDF file (only runs locally):
  * PCollection results =
- *   p.apply(TikaIO.parseAll().filepattern("/local/path/to/file.pdf"));
+ *   p.apply(FileIO.match().filepattern("gs://my-bucket/files/*.pdf")
+ *       .continuously(...))
+ *    .apply(FileIO.readMatches())
+ *    .apply(TikaIO.parseFiles());
  * }
          
- *
- * Warning: the API of this IO is likely to change in the next release.

Subject: [PATCH 551/578] [BEAM-3054] Uses locale-insensitive number formatting
 in ESIO and tests

The ESIO5 test framework will randomly switch the locale of the current
test, and hence it discovered this bug: this is an actual bug.

This commit switches %d to %s where appropriate, i.e. where a
machine-readable decimal number in US locale is required.

Subject: [PATCH 565/578] Add sdks/java/fn-execution

This module contains java code shared by both the SDK harness and
Runners. It does not depend on the Java SDK. Runner harness
libraries will depend on this module, and are not permitted to interact
with SDK constructs.

+ * Stream-lib library. 
          
+ * The original paper of the HyperLogLog is available here. 
          
+ * A paper from the same authors to have a clearer view of the algorithm is available here. 
          
+ * Google's HyperLogLog+ version is detailed in this paper.
+ *
+ * 
          Parameters
          
+ *
+ * 
          Two parameters can be tuned in order to control the computation's accuracy:
+ *
+ * 
            
+ *   
          • Precision: {@code p} 
            
+ *       Controls the accuracy of the estimation. The precision value will have an impact on the
+ *       number of buckets used to store information about the distinct elements. 
            
+ *       In general one can expect a relative error of about {@code 1.1 / sqrt(2^p)}. The value
+ *       should be of at least 4 to guarantee a minimal accuracy. 
            
+ *       By default, the precision is set to {@code 12} for a relative error of around {@code 2%}.
+ *   
          • Sparse Precision: {@code sp} 
            
+ *       Used to create a sparse representation in order to optimize memory and improve accuracy at
+ *       small cardinalities. 
            
+ *       The value of {@code sp} should be greater than {@code p}, but lower than 32. 
            
+ *       By default, the sparse representation is not used ({@code sp = 0}). One should use it if
+ *       the cardinality may be less than {@code 12000}.
+ * 
          
+ *
+ * 
          Examples
          
+ *
+ * 
          There are 2 ways of using this class:
+ *
+ * 
            
+ *   
          • Use the {@link PTransform}s that return {@code PCollection} corresponding to the
+ *       estimate number of distinct elements in the input {@link PCollection} of objects or for
+ *       each key in a {@link PCollection} of {@link KV}s.
+ *   
          • Use the {@link ApproximateDistinctFn} {@code CombineFn} that is exposed in order to make
+ *       advanced processing involving the {@link HyperLogLogPlus} structure which resumes the
+ *       stream.
+ * 
          
+ *
+ * 
          Using the Transforms
          
+ *
+ * 
          Example 1: globally default use
          
+ *
+ * 
          {@code
+ * PCollection input = ...;
+ * PCollection hllSketch = input.apply(ApproximateDistinct.globally());
+ * }
          
+ *
+ * 
          Example 2: per key default use
          
+ *
+ * 
          {@code
+ * PCollection input = ...;
+ * PCollection hllSketches = input.apply(ApproximateDistinct
+ *                .perKey());
+ * }
          
+ *
+ * 
          Example 3: tune precision and use sparse representation
          
+ *
+ * 
          One can tune the precision and sparse precision parameters in order to control the accuracy
+ * and the memory. The tuning works exactly the same for {@link #globally()} and {@link #perKey()}.
+ *
+ * 
          {@code
+ * int precision = 15;
+ * int sparsePrecision = 25;
+ * PCollection input = ...;
+ * PCollection hllSketch = input.apply(ApproximateDistinct
+ *                .globally()
+ *                .withPrecision(precision)
+ *                .withSparsePrecision(sparsePrecision));
+ * }
          
+ *
+ * 
          Using the {@link ApproximateDistinctFn} CombineFn
          
+ *
+ * 
          The CombineFn does the same thing as the transform but it can be used in cases where you want
+ * to manipulate the {@link HyperLogLogPlus} sketch, for example if you want to store it in a
+ * database to have a backup. It can also be used in stateful processing or in {@link
+ * org.apache.beam.sdk.transforms.CombineFns.ComposedCombineFn}.
+ *
+ * 
          Example 1: basic use
          
+ *
+ * 
          This example is not really interesting but show how you can properly create an {@link
+ * ApproximateDistinctFn}. One must always specify a coder using the {@link
+ * ApproximateDistinctFn#create(Coder)} method.
+ *
+ * 
          {@code
+ * PCollection input = ...;
+ * PCollection output = input.apply(Combine.globally(ApproximateDistinctFn
+ *                 .create(BigEndianIntegerCoder.of()));
+ * }
          
+ *
+ * 
          Example 2: use the {@link CombineFn} in a stateful {@link ParDo}
          
+ *
+ * 
          One may want to use the {@link ApproximateDistinctFn} in a stateful ParDo in order to make
+ * some processing depending on the current cardinality of the stream. 
          
+ * For more information about stateful processing see the blog spot on this topic here.
+ *
+ * 
          Here is an example of {@link DoFn} using an {@link ApproximateDistinctFn} as a {@link
+ * org.apache.beam.sdk.state.CombiningState}:
+ *
+ * 
          
+ * {@literal class StatefulCardinality extends DoFn} {
+ *   {@literal @StateId}("hyperloglog")
+ *   {@literal private final StateSpec>}
+ *      indexSpec;
+ *
+ *   {@literal public StatefulCardinality(ApproximateDistinctFn fn)} {
+ *     indexSpec = StateSpecs.combining(fn);
+ *   }
+ *
+ *  {@literal @ProcessElement}
+ *   public void processElement(
+ *      ProcessContext context,
+ *      {@literal @StateId}("hllSketch")
+ *      {@literal CombiningState hllSketch)} {
+ *     long current = MoreObjects.firstNonNull(hllSketch.getAccum().cardinality(), 0L);
+ *     hllSketch.add(context.element());
+ *     context.output(...);
+ *   }
+ * }
+ * 
          
+ *
+ * 
          Then the {@link DoFn} can be called like this:
+ *
+ * 
          {@code
+ * PCollection input = ...;
+ * ApproximateDistinctFn myFn = ApproximateDistinctFn.create(input.getCoder());
+ * PCollection = input.apply(ParDo.of(new StatefulCardinality<>(myFn)));
+ * }
          
+ *
+ * 
          Example 3: use the {@link RetrieveCardinality} utility class
          
+ *
+ * 
          One may want to retrieve the cardinality as a long after making some advanced processing using
+ * the {@link HyperLogLogPlus} structure. 
          
+ * The {@link RetrieveCardinality} utility class provides an easy way to do so:
+ *
+ * 
          {@code
+ * PCollection input = ...;
+ * PCollection hll = input.apply(Combine.globally(ApproximateDistinctFn
+ *                  .create(new MyObjectCoder())
+ *                  .withSparseRepresentation(20)));
+ *
+ *  // Some advanced processing
+ *  PCollection advancedResult = hll.apply(...);
+ *
+ *  PCollection cardinality = hll.apply(ApproximateDistinct.RetrieveCardinality.globally());
+ *
+ * }
          
+ *
+ * 
          Warning: this class is experimental. Its API is subject to change in future versions of
+ * Beam. For example, it may be merged with the {@link
+ * org.apache.beam.sdk.transforms.ApproximateUnique} transform.

Subject: [PATCH 575/578] Added a preprocessing step to the Cloud Spanner sink.

The general intuition we follow here: if mutations are presorted by the primary key before batching, it is more likely that mutations in the batch will end up in the same partition. It minimizes the number of participants in the distributed transaction on the Cloud Spanner side and leads to a better throughput.

Mutations are encoded before running other steps to avoid paying the serialization price. Primary keys are encoded using OrderedCode library, and ApproximateQuantiles transform is used to sample keys.

Once primary keys are sampled, for each mutation we assign the index of the closest primary key as a key and group by that key. Range deletes are submitted separately.
