[jira] [Commented] (CASSANDRA-10699) Make schema alterations strongly consistent

    [ https://issues.apache.org/jira/browse/CASSANDRA-10699?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16451647#comment-16451647 ] 

Brian O'Neill commented on CASSANDRA-10699:
-------------------------------------------

With this change, will schema alterations be versioned? I think this would be helpful when plugging in other storage engines. [#CASSANDRA-13474]

> Schema changes do not necessarily commute. This has been the case before CASSANDRA-5202, but now is particularly problematic.
> We should employ a strongly consistent protocol instead of relying on marshalling {{Mutation}} objects with schema changes.
