Lars Hofhansl commented on HBASE-4583:
--------------------------------------
You guys used this more extensively at SU than anybody else, I think. Would you
stick to your statement that the upsert complexity and breaking of the general
HBase VERSIONS contract is warranted for the performance gain?
It would probably be am even bigger problem if there's other load (that fills
the memstore) that now unnecessarily needs to be flushed because of many
increments.
> Integrate RWCC with Append and Increment operations

> Currently Increment and Append operations do not work with RWCC and hence a
> client could see the results of multiple such operation mixed in the same
> Get/Scan.
> The semantics might be a bit more interesting here as upsert adds and removes
> to and from the memstore.
