Amit Sela updated BEAM-649:
---------------------------
Assignee: (was: Amit Sela)
> Pipeline "actions" should use foreachRDD via ParDo.
> ---------------------------------------------------
>
> Key: BEAM-649
> URL: https://issues.apache.org/jira/browse/BEAM-649
> Project: Beam
> Issue Type: Bug
> Components: runner-spark
> Reporter: Amit Sela
>
> Spark will execute a pipeline ONLY if it's triggered by an action (batch) /
> output operation (streaming) -
> http://spark.apache.org/docs/1.6.2/streaming-programming-guide.html#output-operations-on-dstreams.
> Currently, such actions in Beam are mostly implemented via ParDo, and
> translated by the runner as a Map transformation (via mapPartitions).
> The runner overcomes this by "forcing" actions on untranslated leaves.
> While this is OK, it would be better in some cases, e.g., Sinks, to apply the
> same ParDo translation but with foreach/foreachRDD instead of
> foreachPartition/mapPartitions.
