> Cache any PCollection implementation if accessed more than once
> ---------------------------------------------------------------
>
> Key: BEAM-649
> URL: https://issues.apache.org/jira/browse/BEAM-649
> Project: Beam
> Issue Type: Improvement
> Components: runner-spark
> Reporter: Amit Sela
> Assignee: Jean-Baptiste Onofré
>
> Currently, the runner will cache any {{PCollection}} implementation - {{RDD}}
> or {{DStream}} - if accessed for the second time.
> This can be further optimized to cache after the first evaluation, if
> accessed again, and also solve issues in BEAM-1206.
