Subject [jira] [Created] (CASSANDRA-4684) Binary protocol: inform clients of schema changes
Date Wed, 19 Sep 2012 08:31:07 GMT
Sylvain Lebresne created CASSANDRA-4684:

             Summary: Binary protocol: inform clients of schema changes
                 Key: CASSANDRA-4684
             Project: Cassandra
          Issue Type: Improvement
    Affects Versions: 1.2.0 beta 1
            Reporter: Sylvain Lebresne
            Assignee: Sylvain Lebresne
            Priority: Minor
             Fix For: 1.2.0 beta 2

It would be nice to inform clients when a schema change occurs as this would allow said client
to maintain the current state of the schema, which might be useful/desirable. To allow that,
we can:
# return that a query has changed the schema (instead of simply a 'void' return), in the same
spirit than CASSANDRA-3707.
# add events notification on schema change.

Just to be clear, the goal is only to inform that a change has occured, the client would still
have to query the system table to know the exact content of the change, but at least it'll
know when to do such query.
