I think this is still an important use case.

@wesm Could you give some more detailed description for this issue？Do you mean that add APIs to write ArrowRecordBatch to byte array and read it？

Wes McKinney / @wesm:
This would mean reading Arrow IPC messages from a memory-map without copying. I think the work to partly enable this to be built is being done in ARROW-3191

@siddharthteotia is this something of interest for the next release to validate the new Java capabilities?
