Subject [jira] [Created] (HBASE-5032) Add DELETE COLUMN into the delete bloom filter
Date Wed, 14 Dec 2011 23:33:31 GMT
Add DELETE COLUMN into the delete bloom filter

                 Key: HBASE-5032
                 URL: https://issues.apache.org/jira/browse/HBASE-5032
             Project: HBase
          Issue Type: Improvement
            Reporter: Liyin Tang
            Assignee: Liyin Tang

Previously, the delete family bloom filter only contains the row key which has the delete
family. It helps us to avoid the top-row seek operation.

This jira attempts to add the delete column into this delete bloom filter as well (rename
the delete family bloom filter as delete bloom filter).

The motivation is to save seek ops for scan time-range queries if we know there is no delete
column for this row/column. 
We can seek directly to the exact timestamp we are interested in, instead of seeking to the
latest timestamp and keeping skipping to found out whether there is any delete column before
the interested timestamp.
