-------------------------------------------
Summary: Binary protocol: inform clients of schema changes
Key: CASSANDRA-4684
URL: https://issues.apache.org/jira/browse/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.
