[jira] [Updated] (HBASE-4469) Avoid top row seek by looking up bloomfilter

["Kannan Muthukkaruppan (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HBASE-4469?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Kannan Muthukkaruppan updated HBASE-4469:
-----------------------------------------

    Description: 
The problem is that when seeking for the row/col in the hfile, we will go to top of the row in order to check for row delete marker (delete family). However, if the bloomfilter is enabled for the column family, then if a delete family operation is done on a row, the row is already being added to bloomfilter. We can take advantage of this factor to avoid seeking to the top of row.
