Subject [jira] [Commented] (HBASE-5520) Support reseek() at RegionScanner
Date Mon, 12 Mar 2012 14:52:39 GMT

    [ https://issues.apache.org/jira/browse/HBASE-5520?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13227581#comment-13227581

ramkrishna.s.vasudevan commented on HBASE-5520:
-----------------------------------------------

@Lars and @Stack
Updated the api to take row instead of kv.
@Lars
Yes SEEK_NEXT_USING_HINT is a definite gain but this reseek will help to avoid that one problem
that filters have to reseek one more kv incase where we know the row that we need to seek
to.

Just a thought of me and Anoop.  Pls let us know your suggestions and comments.
