Panagiotis Garefalakis updated HIVE-24703:
------------------------------------------
Parent: (was: HIVE-23553)
Issue Type: Improvement (was: Sub-task)
> LLAP move RowGroup reading to StrippePlanner
> --------------------------------------------
>
> Key: HIVE-24703
> URL: https://issues.apache.org/jira/browse/HIVE-24703
> Project: Hive
> Issue Type: Improvement
> Reporter: Panagiotis Garefalakis
> Priority: Major
>
> LlapDataREader is almost identical to ORC's DataREader, however the main
> issue the readFileData method of the latter takes a DiskRangeList instead of
> a BufferChunkList.
> ORC-1.6 uses a separate StripePlanner that reads RowGroups converting them to
> BufferChunks while in LLAP we are doing our own custom planning with
> DiskRanges.
> I am opening this ticket to explore moving LLAP to Stripe planning
