Subject [jira] [Commented] (CASSANDRA-4017) Unify migrations
Date Thu, 08 Mar 2012 07:07:02 GMT


Jonathan Ellis commented on CASSANDRA-4017:

Tagging 1.1.0 since this may change the schema communication protocol, and I don't want to
break things twice...

> Now that we can send a schema as a RowMutation, there's no need to keep separate add/drop/update
migration classes around.  Let's just send the schema to our counterparts and let them figure
out what changed.  Currently we have "figure out what changed" code to both generate migrations
on the sender, and for application on the target, which adds complexity.
