Subject [jira] [Commented] (CASSANDRA-7342) CAS writes does not have hint functionality.
Date Wed, 11 Jun 2014 21:31:03 GMT


sankalp kohli commented on CASSANDRA-7342:

I was thinking of ways to do it. Can we use the same hints CF and add a new column called
cas_commit and save commits there. This way we can distinguish while replaying the logs whether
it is a commit or a normal mutation. 

    target_id uuid,
    hint_id timeuuid,
    message_version int,
    mutation blob,
    cas_commit blob,
    PRIMARY KEY (target_id, hint_id, message_version)
