Subject [jira] [Updated] (HBASE-8388) Use ROW bloom filter for scanning
Date Sun, 21 Apr 2013 22:27:17 GMT

     [ https://issues.apache.org/jira/browse/HBASE-8388?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Lars Hofhansl updated HBASE-8388:
---------------------------------

    Attachment: 8388-0.94-v1.txt

New 0.94 patch incorporating Ted's fix and also makes sure that deleteBFs are still consulted
when the ROW BF is set.
(Not sure why the only case we do not consult the delete BF is ROWCOL)

> Currently only ROWCOL BFs are used during the scanning process. It seems we could make
use of ROW BFs in StoreFileScanner.requestSeek.
