> Are you sure the last commit is consistent with the discussion above? I'm not quite following. @srowen As @cloud-fan suggested in the comment below, the only change needed is to keep the storage level in `scalaDataFrame.persist()` and `pysparkDataframe.persist()` same i.e. `StorageLevel(true, true, false, true)` > I'm not sure if it worth. The CachedBatch is mostly a wrapper of byte[] so keeping the serialized or deserialized form in memory doesn't matter too much. I think the important thing is to keep Scala and Python cache/persistent consistent, although the Scala side has more builtin StorageLevels. @cloud-fan let me know in case I misunderstood your point or you intend to achieve the same thing in some other way.
