             Summary: Allow HashTable/SyncTable to perform rawScan when comparing cells
                 Key: HBASE-26276
                 URL: https://issues.apache.org/jira/browse/HBASE-26276
             Project: HBase
          Issue Type: Improvement
            Reporter: Wellington Chevreuil
            Assignee: Wellington Chevreuil


We had noticed some of our customers having inconsistent results when running HashTable/SyncTable in scenarios described previously by HBASE-21596. As discussed on HBASE-21596, one alternative to avoid such inconsistencies, is to set 'NEW_VERSION_BEHAVIOUR' introduced by HBASE-15968. That, however, does rely on the order of operations, which can't be guaranteed when standard replication (not serial replication) is being used, which is the case on the majority of our customers.

A possible workaround is to place delete markers to every single cell version returned on a raw scan, and setting a high value to the scan number of versions to be read.
