Jean-Baptiste Onofré commented on BEAM-918:

It's what we discussed together and of course, I fully agree ;)

Do you mind if I work on this ?

> Spark provides different "STORAGE_LEVEL"s for caching RDDs (disk, memory, ser/de, etc.).
> The runner decides on caching when necessary, for example when a RDD is accessed repeatedly.
> For batch, we can let users set their preferred STORAGE_LEVEL via SparkPipelineOptions.
> Note: for streaming we force a "MEMORY_ONLY", since (among other things) the runner heavily
relies on stateful operations, and it's natural for streaming to happen in memory.
