Subject [jira] [Commented] (CASSANDRA-4545) add cql support for batchlog
Date Mon, 17 Sep 2012 10:45:07 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-4545?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13456932#comment-13456932
] 

Sylvain Lebresne commented on CASSANDRA-4545:
---------------------------------------------

As a side note let me remark that a BATCH is not synonymous of "non atomic", since everything
within the same partition key will be atomic and isolated (and in a fair amount of cases,
those can be done with a single INSERT/UPDATE).

It would be nice if whatever choice of syntax we make here don't suggest too much that what
is atomic is not.

And as a side side note, it would be nice to make "batchlog" writes skip the batchlog patch
if the batch is on only one partition key.
