>
> 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.
