Date Mon, 01 Oct 2012 16:15:07 GMT
Sylvain Lebresne created CASSANDRA-4738:
-------------------------------------------

             Summary: Improve CQL3 batchlog support 
                 Key: CASSANDRA-4738
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-4738
             Project: Cassandra
          Issue Type: Improvement
            Reporter: Sylvain Lebresne
            Assignee: Sylvain Lebresne
            Priority: Minor
             Fix For: 1.2.0 beta 2
         Attachments: 4738.txt

This is a follow-up on CASSANDRA-4545. We've made batch be atomic by default, however it is
actually possible for normal inserts to not be atomic by default thanks to the support of
the IN notation.

I don't think this is very coherent so I suggest the two following changes:
* make sure normal inserts/deletes are always atomic ("logged")
* make sure we use mutate (rather than mutateAtomically) if there is only one mutation (i.e.
use the batch log in normal inserts/deletes only if there is an IN).

And if people really want to do "unlogged" insert with IN, they can put the insert inside
an unlogged batch.
