Subject [jira] [Commented] (HBASE-9753) Excessive readpoints checks in MemstoreScanner
Date Sun, 13 Oct 2013 01:58:42 GMT

    [ https://issues.apache.org/jira/browse/HBASE-9753?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13793559#comment-13793559

Lars Hofhansl commented on HBASE-9753:

I think I was too eager filing tickets :)

Yep, we should be able to completely do away with MultiVersionConsistencyControl.perThreadReadPoint.

In the same way you suggested to pass the readpoint to the MemstoreScanner consructor we should
be able to pass the same to all StoreFileScanners. That would not only be more performant,
it would also be easier on in the eye.

If you have time to do a patch here or on HBASE-9754 that'd be awesome, otherwise I'll pick
it up next week.
