Release 1.6.0

Backend Changes

Breaking Changes!!!

• The storage implementations no longer write the parentSpanID field to storage (#856).
  If you are upgrading to this version, you must upgrade query service first!

• 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)

  When submitting spans in Thrift format to HTTP endpoint /api/traces,
  the format argument is no longer required, but the Content-Type header
  must be set to "application/vnd.apache.thrift.binary".

• Change metric tag from "service" to "svc" (#883) by Won Jun Jang (@black-adder)

New Features

• Add Kafka as a Storage Plugin (#862) by David Yeghshatyan (@davit-y)

  The collectors can be configured to write spans to Kafka for further data mining.

• Package static assets inside the query-service binary (#918) by Yuri Shkuro (@yurishkuro)

  It is no longer necessary (but still possible) to pass the path to UI static assets
  to jaeger-query and jaeger-standalone binaries.

• Replace domain model with Protobuf/gogo-generated model (#856) by Yuri Shkuro (@yurishkuro)

  First step towards switching to Protobuf and gRPC.

Highlights

HotROD Demo

By popular demand, the HotROD demo is now available as a Docker image, jaegertracing/example-hotrod.

Centrally Configurable Sampling Policies

Jaeger clients have long supported centrally controlled per-service sampling policies. We are still working on rolling out full adaptive sampling to the open source version, but now the collectors allow configuring sampling strategies via a configuration file (see Sampling section in the documentation) that can be pushed to the clients without manual re-configuration of the microservices.

Running Jaeger UI Behind Reverse Proxy

Another popular request is to support running Jaeger UI with a custom site prefix, such as mycompany.com/jaeger. Now possible with the new query.base-path command line argument or the QUERY_BASE_PATH environment variable.

Google Analytics Support in the UI

If you are running a tracing team in your company, you probably want to measure how other engineers are using Jaeger. Jaeger UI supports Google Analytics, see Deployment documentation on how to configure it.
