Subject [jira] [Commented] (HIVE-5276) Skip useless string encoding stage for hiveserver2
Date Fri, 08 Nov 2013 01:08:17 GMT

    [ https://issues.apache.org/jira/browse/HIVE-5276?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13816875#comment-13816875

Navis commented on HIVE-5276:
-----------------------------

[[~brocknoland] Ah, sorry. When I've been doing this, I've assumed that one input row would
result one to zero output row, which is generally right. But with second thought, it's possible
fetch task to have UDTF Operator which would make arbitrary number of output rows. So I've
changed the patch status. I'll update this later.

> Current hiveserver2 acquires rows in string format which is used for cli output. Then
convert them into row again and convert to final format lastly. This is inefficient and memory
consuming.
