Subject [jira] [Commented] (HBASE-9769) Improve performance of a Scanner with explicit column list when rows are small/medium size
Date Thu, 17 Oct 2013 03:51:44 GMT

    [ https://issues.apache.org/jira/browse/HBASE-9769?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13797574#comment-13797574
] 

Vladimir Rodionov commented on HBASE-9769:
------------------------------------------

1. Its not a client side filter (keeps only column qualifiers - no column families). I decided
to put it into regionserver, but I can move to hbase-client
2. OK, shouldUse is better
3. you right this check is not needed.

I will add tests, of course.
