From 473d56ca105bce822215acb06f47e6a3c808f882 Mon Sep 17 00:00:00 2001 From: Aljoscha Krettek Date: Sun, 25 Sep 2016 20:58:16 +0200 Subject: [PATCH 1/7] [FLINK-4877] Rename TimeServiceProvider to ProcessingTimeService The name is clashing with the soon-to-be-added TimerService/InternalTimerService which is meant as an interface for dealing with both processing time and event time. TimeServiceProvider is renamed to ProcessingTimeService to reflect the fact that it is a low-level utility that only deals with "physical" processing-time trigger tasks. --- .../ContinuousFileMonitoringTest.java | 4 +- .../fs/bucketing/BucketingSink.java | 6 +- .../kafka/internals/AbstractFetcher.java | 8 +-- .../AbstractFetcherTimestampsTest.java | 8 +-- .../kafka/testutils/MockRuntimeContext.java | 8 +-- .../source/ContinuousFileReaderOperator.java | 2 +- .../api/operators/AbstractStreamOperator.java | 17 +++--- .../streaming/api/operators/StreamSource.java | 2 +- .../api/operators/StreamSourceContexts.java | 14 ++--- .../operators/StreamingRuntimeContext.java | 6 +- .../operators/ExtractTimestampsOperator.java | 8 +-- ...mestampsAndPeriodicWatermarksOperator.java | 8 +-- ...ctAlignedProcessingTimeWindowOperator.java | 6 +- .../windowing/EvictingWindowOperator.java | 2 +- .../operators/windowing/WindowOperator.java | 10 ++-- ...ovider.java => ProcessingTimeService.java} | 2 +- .../streaming/runtime/tasks/StreamTask.java | 16 +++--- ....java => SystemProcessingTimeService.java} | 8 +-- ...er.java => TestProcessingTimeService.java} | 4 +- .../operators/StreamSourceOperatorTest.java | 47 ++++++++++------ .../operators/StreamTaskTimerTest.java | 6 +- ...ava => TestProcessingTimeServiceTest.java} | 18 +++--- ...ampsAndPeriodicWatermarksOperatorTest.java | 13 ++++- ...ignedProcessingTimeWindowOperatorTest.java | 49 ++++++++-------- ...ignedProcessingTimeWindowOperatorTest.java | 56 +++++++++---------- .../operators/windowing/NoOpTimerService.java | 4 +- .../windowing/WindowOperatorTest.java | 14 ++--- .../runtime/tasks/StreamTaskTestHarness.java | 6 +- ...a => SystemProcessingTimeServiceTest.java} | 16 +++--- ...eyedOneInputStreamOperatorTestHarness.java | 8 +-- .../flink/streaming/util/MockContext.java | 23 -------- .../OneInputStreamOperatorTestHarness.java | 43 ++++++-------- .../streaming/util/WindowingTestHarness.java | 6 +- .../runtime/StreamTaskTimerITCase.java | 10 ++-- 34 files changed, 222 insertions(+), 236 deletions(-) rename flink-streaming-java/src/main/java/org/apache/flink/streaming/runtime/tasks/{TimeServiceProvider.java => ProcessingTimeService.java} (98%) rename flink-streaming-java/src/main/java/org/apache/flink/streaming/runtime/tasks/{DefaultTimeServiceProvider.java => SystemProcessingTimeService.java} (95%) rename flink-streaming-java/src/main/java/org/apache/flink/streaming/runtime/tasks/{TestTimeServiceProvider.java => TestProcessingTimeService.java} (96%) rename flink-streaming-java/src/test/java/org/apache/flink/streaming/runtime/operators/{TestTimeProviderTest.java => TestProcessingTimeServiceTest.java} (84%) rename flink-streaming-java/src/test/java/org/apache/flink/streaming/runtime/tasks/{DefaultTimeServiceProviderTest.java => SystemProcessingTimeServiceTest.java} (93%) diff --git a/flink-fs-tests/src/test/java/org/apache/flink/hdfstests/ContinuousFileMonitoringTest.java b/flink-fs-tests/src/test/java/org/apache/flink/hdfstests/ContinuousFileMonitoringTest.java index 36b5c5ecbe9e6..971d5f85802fc 100644 --- a/flink-fs-tests/src/test/java/org/apache/flink/hdfstests/ContinuousFileMonitoringTest.java +++ b/flink-fs-tests/src/test/java/org/apache/flink/hdfstests/ContinuousFileMonitoringTest.java @@ -34,7 +34,7 @@ import org.apache.flink.streaming.api.functions.source.SourceFunction;

InternalTimerService is the new interface that has the same functionality that WindowOperator used to have. TimerService is the user facing interface that does not allow dealing with namespaces/payloads and also does not allow deleting timers. There is a default implementation in HeapInternalTimerService that can checkpoint timers to a stream and also restore from a stream. Right now, this is managed in AbstractStreamOperator and operators can ask for an InternalTimerService. This also adds tests for HeapInternalTimerService. This adds two new user functions: - TimelyFlatMapFunction: an extension of FlatMapFunction that also allows querying time and setting timers - TimelyCoFlatMapFunction: the same, but for CoFlatMapFunction There are two new StreamOperator implementations for these that use the InternalTimerService interface. This also adds tests for the two new operators. This also adds the new interface KeyContext that is used for setting/querying the current key context for state and timers. Timers are always scoped to a key, for now. Also, this moves the handling of watermarks for both one-input and two-input operators to AbstractStreamOperators so that we have a central ground-truth. --- .../state/RocksDBAsyncSnapshotTest.java | 17 +- .../flink/storm/wrappers/BoltWrapper.java | 7 -
