Amitanand Aiyer commented on HBASE-5241:
----------------------------------------

After some discussion, we figured that skipping to the next column, vs skipping 
to next KV shouldn't make so much of a difference. So, headed in this direction 
(as opposed to trying to create indices or change the sort order).


Will need to see once the patch is complete, if the read performance gets 
affected significantly.

> Suppose that we have a delete row, and then followed by the put. The delete

> Now that we are flushing the memstoreTS to disk, along with the KVs, we

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

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