[jira] [Updated] (HBASE-5241) Deletes should not mask Puts that come after it.

["Zhihong Yu (Updated) (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HBASE-5241?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Zhihong Yu updated HBASE-5241:
------------------------------

     Description: 
Suppose that we have a delete row, and then followed by the put. The delete row
can mask the put, unless there was a major compaction in between.

Now that we are flushing the memstoreTS to disk, along with the KVs, we should be able
to differentiate whether or not the Put happened after the Delete and offer better 
delete semantics.

Couldn't find a pre-existing JIRA that already discusses this, so creating one.

Seems related to https://issues.apache.org/jira/browse/HBASE-2406, but is not quite the same.

        Priority: Major  (was: Minor)
    Hadoop Flags: Incompatible change

This is a nice initiative.
