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".
