Pavel Yaskevich commented on CASSANDRA-2583:
--------------------------------------------
835669aee8dc0ba14a37594e1ff07d056c74a3ea is git-svn-id:
https://svn.apache.org/repos/asf/cassandra/trunk@1100900
13f79535-47bb-0310-9956-ffa450edef68, but I see that it depends on
CASSANDRA-2476 so please apply this one after CASSANDRA-2476 if possible.

> Currently we turn batches into one RowMutation per statement. This is
> suboptimal if we have multiple statements operating on the same row. This
> could happen either with generated code, or deliberately to allow different
> options to different columns in the row, e.g. for TTLs (CASSANDRA-2476).
