Varun Sharma commented on HBASE-4583:
-------------------------------------
I see - i thought since 0.94 is the current stable version, the one we
currently use and we are going heavily use it for counters - we wanted to see
if we could use it. Eventually, the other JIRA i am looking into (allowing puts
+ increments + deletes) in a single mutation is also important for the use case
- basically to have counts + puts go in as a single mutation and have a
consistent view of the table - also, it helps cut down write latency for us.
But judging from the reaction, it looks like we might not want that other JIRA
to go into 0.94 either (even if we possibly flag protected the change) - in
which case, I am okay with this not going through (we can probably use a
manually patched version for our usage). Btw, when is the 0.96 expected to ship
- it has lots of good features/fixes in it.
Thanks !

> Currently Increment and Append operations do not work with RWCC and hence a

> Get/Scan.
> The semantics might be a bit more interesting here as upsert adds and removes
> to and from the memstore.
