Lars Hofhansl updated HBASE-4583:
---------------------------------
Attachment: 4583-mixed.txt
Here's what I mean:
Use upsert for Increment and Append if VERSIONS == 1, use Store.add otherwise
(just like Puts in that case)
TODO:
I can easily adept Append to take the TS (in fact it already does, just not per
column); for Increments it's a bit more tricky as currently just serializes a
column -> long mapping.
> 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.
