-------------------------------------------
Summary: Don't announce schema version until we've loaded the
changes locally
Key: CASSANDRA-5904
URL: https://issues.apache.org/jira/browse/CASSANDRA-5904
Project: Cassandra
Issue Type: Bug
Reporter: Sylvain Lebresne
Assignee: Sylvain Lebresne
Priority: Minor
Currently, we call updateSchemaAndAnnounce (which sets the schema version in
the system table and announce it on gossip) in DefsTable.mergeSchema as soon as
we've persisted the schema mutation but *before* we've actually loaded
new/updated KS/CF locally. This makes it impossible to reliably check for
schema agreement in a cluster as even if all nodes have the same version set in
the system tables, you could still get an insert on a new table rejected
because the table hasn't been loaded yet.
