[jira] Created: (CASSANDRA-347) disabling commitlog as alternative to binarymemtable?

disabling commitlog as alternative to binarymemtable?
-----------------------------------------------------

                 Key: CASSANDRA-347
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-347
             Project: Cassandra
          Issue Type: New Feature
            Reporter: Jonathan Ellis
            Assignee: Jonathan Ellis


IMO it's worth seeing if we can do without BMt since it's a secondary code path that doesn't see much use.  so you'll get done with BMT, then nobody will really test it until the next big import job at which point little bugs will have crept in because it just doesn't get run much.

    Resolution: Won't Fix

Serialization really is a bottleneck...  I'm afraid binarymemtable isn't going anywhere :)

Jonathan Ellis updated CASSANDRA-347:
-------------------------------------

    Attachment: 347.patch

proof of concept patch.  does not address things like system CFs that don't grow large enough to flush to disk on their own.
