Subject [jira] [Commented] (CASSANDRA-4545) add cql support for batchlog
Date Mon, 17 Sep 2012 13:58:07 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-4545?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13457027#comment-13457027
] 

Jonathan Ellis commented on CASSANDRA-4545:
-------------------------------------------

bq. it would be nice to make "batchlog" writes skip the batchlog patch if the batch is on
only one partition key

true, although that does mean clients need to be aware of the difference as well (clients
need to retry if it timesout during the batchlog write, or if it times out during the data
write and there is only one key), so maybe it's simpler to just say "clients should be responsible
for this optimization" in the first place.
