> Use a "poison pill" to stop streaming tests as they finish.
> -----------------------------------------------------------
>
> Key: BEAM-1562
> URL: https://issues.apache.org/jira/browse/BEAM-1562
> Project: Beam
> Issue Type: Improvement
> Components: runner-spark
> Reporter: Amit Sela
> Assignee: Amit Sela
>
> Streaming tests use a timeout that has to take a large enough buffer to avoid
> slow runtimes stopping before test completes.
> We can introduce a "poison pill" based on an {{EndOfStream}} element that
> would be counted in a Metrics/Aggregator to know all data was processed.
> This requires the Spark runner to stop blocking the execution of a streaming
> pipeline until it's complete - which is something relevant to
> {{PipelineResult}} (re)design that is being discussed in BEAM-849
