Major Description
To fully support Spark RDD's persistence options, we need a few features to provide.
We need to support:
- Default persistence on memory or disk.
- Persistence using memory and disk at the same time (spill).
- Persistence on off-heap memory
- Replication for persisted data
- Disable changing persist strategy after a RDD is executed
- Report the actual state of cached data to optimizer
