[jira] [Commented] (CASSANDRA-13426) Make all DDL statements idempotent and not dependent on global state

    [ https://issues.apache.org/jira/browse/CASSANDRA-13426?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16287526#comment-16287526 ] 

Aleksey Yeschenko commented on CASSANDRA-13426:
-----------------------------------------------

Force-pushed a rebased branch with some updates. At this point it's largely done, missing some optimisations on shallow vs. deep diffs for delta serialisation, and good test coverage.

> A follow-up to CASSANDRA-9425 and a pre-requisite for CASSANDRA-10699.
> It's necessary for the latter to be able to apply any DDL statement several times without side-effects. As part of the ticket I think we should also clean up validation logic and our error texts. One example is varying treatment of missing keyspace for DROP TABLE/INDEX/etc. statements with IF EXISTS.
