[jira] [Updated] (HBASE-4583) Integrate RWCC with Append and Increment operations

["Lars Hofhansl (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HBASE-4583?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

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.

> 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.
