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

Avoid top row seek by looking up bloomfilter
--------------------------------------------

                 Key: HBASE-4469
                 URL: https://issues.apache.org/jira/browse/HBASE-4469
             Project: HBase
          Issue Type: Improvement
            Reporter: Liyin Tang
            Assignee: Liyin Tang


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 will be
added to bloomfilter. We can take advantage of this factor to avoid seeking to the top of
row.
