Summary: Transform Reshuffle directly in Spark runner
Key: BEAM-1623
URL: https://issues.apache.org/jira/browse/BEAM-1623
Project: Beam
Issue Type: Improvement
Components: runner-spark
Reporter: Aviem Zur
Assignee: Amit Sela
Transform {{Reshuffle}} directly in Spark runner.
Spark's {{repartition}} is logically equivalent to {{Reshuffle}} and will cause
the required fusion break without incurring the overhead of {{groupByKey}} (In
streaming pipelines this will use {{updateStateByKey}}) compared to a simple
{{repartition}}.
