Subject [jira] [Commented] (CASSANDRA-4542) add atomic_batch_mutate method
Date Sun, 09 Sep 2012 04:16:08 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-4542?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13451486#comment-13451486
] 

Jonathan Ellis commented on CASSANDRA-4542:
-------------------------------------------

I wouldn't mind adding an insertLocal path there, but optimizing atomic batches for single
node clusters isn't a super high priority.  The extra commitlog write is going to dominate
the extra work anyway.

> atomic_batch_mutate will have the same parameters as batch_mutate, but will write to
the batchlog before attempting distribution to the batch rows' replicas.
