> Key: BEAM-12439
> URL: https://issues.apache.org/jira/browse/BEAM-12439
> Project: Beam
> Issue Type: Improvement
> Components: runner-flink, runner-spark, sdk-py-core
> Reporter: Kyle Weaver
> Priority: P3
> Time Spent: 3h 20m
> Remaining Estimate: 0h
>
> If multiple Beam pipelines are run on Spark or Flink from the same Python
> script, currently a new Java job server will be created for each pipeline.
> This can waste lots of resources (i.e. memory), since job servers are often
> functionally equivalent and therefore reusable.
