[jira] [Created] (CASSANDRA-7600) Schema change notifications sent for no-op DDL statements

Tyler Hobbs created CASSANDRA-7600:
--------------------------------------

             Summary: Schema change notifications sent for no-op DDL statements
                 Key: CASSANDRA-7600
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-7600
             Project: Cassandra
          Issue Type: Bug
          Components: Core
            Reporter: Tyler Hobbs
            Assignee: Tyler Hobbs
             Fix For: 2.1.1


When schema changes are made with {{IF \[NOT\] EXISTS}} conditions, we return schema change messages (and push out schema change notifications) even if the {{IF \[NOT\] EXISTS}} condition makes it a no-op.

This results in extra work for native protocol drivers, which typically wait for schema agreement and refresh their schema metadata when schema changes occur.
