Release 1.10.0

Backend Changes

Breaking Changes

• Remove cassandra SASI indices (#1328, @black-adder)

Migration Path:

1. Run plugin/storage/cassandra/schema/migration/v001tov002part1.sh which will copy dependencies into a csv, update the dependency UDT, create a new dependencies_v2 table, and write dependencies from the csv into the dependencies_v2 table.
2. Run the collector and query services with the cassandra flag cassandra.enable-dependencies-v2=true which will instruct jaeger to write and read to and from the new dependencies_v2 table.
3. Update spark job to write to the new dependencies_v2 table. The feature will be done in #58.
4. Run plugin/storage/cassandra/schema/migration/v001tov002part2.sh which will DELETE the old dependency table and the SASI index.

Users who wish to continue to use the v1 table don't have to do anything as the cassandra flag cassandra.enable-dependencies-v2 will default to false. Users may migrate on their own timeline however new features will be built solely on the dependencies_v2 table. In the future, we will remove support for v1 completely.

UI Changes

Release 1.9.0

Backend Changes

Breaking Changes

• Change Elasticsearch index prefix from : to - (#1284, @pavolloffay)

Changed index prefix separator from : to - because Elasticsearch 7 does not allow : in index name.
Jaeger query still reads from old indices containing - as a separator, therefore no configuration or migration changes are required.

• Add CLI configurable es.max-num-spans while retrieving spans from ES (#1283, @annanay25)

The default value is set to 10000. Before no limit was applied.

• Update to jaeger-lib 2 and latest sha for jaeger-client-go, to pick up refactored metric names (#1282, @objectiser)

Update to latest version of jaeger-lib, which includes a change to the naming of counters exported to
prometheus, to follow the convention of using a _total suffix, e.g. jaeger_query_requests is now
jaeger_query_requests_total.

Jaeger go client metrics, previously under the namespace jaeger_client_jaeger_ are now under
jaeger_tracer_.

• Add gRPC metrics to agent (#1180, @pavolloffay)

The following metrics:

jaeger_agent_tchannel_reporter_batch_size{format="jaeger"} 0
jaeger_agent_tchannel_reporter_batch_size{format="zipkin"} 0

• Various changes around metrics produced by jaeger-query: Names scoped to the query component, generated for all span readers (not just ES), consolidate query metrics and include result tag (#1074, #1075 and #1096, @objectiser)

jaeger_find_traces_okLatency_bucket{le="0.005"} 0

Backend Changes

Breaking Changes!!!

• The storage implementations no longer write the parentSpanID field to storage (#856).

• Update Dockerfiles to reference executable via ENTRYPOINT (#815) by Zachary DiCesare (@zdicesare)

  It is no longer necessary to specify the binary name when passing flags to containers.
  For example, to execute the help command of the collector, instead of

  $ docker run -it --rm jaegertracing/jaeger-collector /go/bin/collector-linux help
  

  run

  $ docker run -it --rm jaegertracing/jaeger-collector help
  

• Detect HTTP payload format from Content-Type (#916) by Yuri Shkuro (@yurishkuro)
