---------------------------------------
Summary: LLAP: support non-vectorized execution in IO
Key: HIVE-13617
URL: https://issues.apache.org/jira/browse/HIVE-13617
Project: Hive
Issue Type: Bug
Reporter: Sergey Shelukhin
Two approaches - a separate decoding path, into rows instead of VRBs; or
decoding VRBs into rows. I think the latter might be better - it's not a hugely
important path, and perf in non-vectorized case is not the best anyway, so it's
better to make do with much less new code and architectural disruption.
Some ORC patches in progress introduce an easy to reuse (or so I hope, anyway)
VRB-to-row conversion, so we should just use that.
