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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
