> Incomplete JobService API Semantics
> -----------------------------------
>
> Key: BEAM-6442
> URL: https://issues.apache.org/jira/browse/BEAM-6442
> Project: Beam
> Issue Type: Test
> Components: beam-model
> Affects Versions: 2.9.0
> Reporter: Sam Rohde
> Priority: P2
> Labels: stale-P2
>
> The JobService API (beam_job_api.proto) allows for the possibility of never
> seeing messages or states with Get(State|Message)Stream. This is because the
> Get(State|Message)Stream calls need to have the job id which can only be
> obtained from the RunJobResponse. But in order to see all messages/states the
> streams need to be opened before the job starts.
> This is fine in Dataflow as the preparation_id == job_id, but this is not
> true in Flink.
> Fix is to modify the API to only keep a single id to be used between the
> preparation/run APIs.
> Consumers of the API will have to be modified to meet the new semantics.
