Subject [jira] [Created] (CASSANDRA-2583) optimize batches containing multiple updates to the same rows
Date Fri, 29 Apr 2011 15:26:03 GMT
optimize batches containing multiple updates to the same rows
-------------------------------------------------------------

                 Key: CASSANDRA-2583
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-2583
             Project: Cassandra
          Issue Type: Improvement
          Components: API
    Affects Versions: 0.8 beta 1
            Reporter: Jonathan Ellis
            Assignee: Pavel Yaskevich
            Priority: Minor
             Fix For: 0.8.1


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).
