Subject [jira] [Commented] (HBASE-8388) Use ROW bloom filter for scanning
Date Thu, 25 Apr 2013 06:20:17 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8388?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13641478#comment-13641478
] 

Anoop Sam John commented on HBASE-8388:
---------------------------------------

This will be very useful with the secondary indexing that we had done. (Seek+ read some thing
like multiple Gets in a region). Agree with Lars on the risk of changing this area of code.

[~priyank.rastogi], [~jyothi.mandava] can you guys check with this?

> Currently only ROWCOL BFs are used during the scanning process. It seems we could make
use of ROW BFs in StoreFileScanner.requestSeek.
> See HBASE-8362 for background.
