Sergey Shelukhin updated HIVE-13617:
------------------------------------
Status: Patch Available (was: Open)
> 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
> Assignee: Sergey Shelukhin
> Attachments: HIVE-13617-wo-11417.patch, HIVE-13617.patch,
> HIVE-15396-with-oi.patch

>
> Two approaches - a separate decoding path, into rows instead of VRBs; or
> decoding VRBs into rows on a higher level (the original LlapInputFormat). 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.
