    • Priority: Major
    • Resolution: Unresolved
    • Affects Version/s: None
    • Fix Version/s: 0.2

      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
