patrick lee reassigned CASSANDRA-14879: --------------------------------------- Assignee: patrick lee > Log DDL statements on coordinator > --------------------------------- > > Key: CASSANDRA-14879 > URL: https://issues.apache.org/jira/browse/CASSANDRA-14879 > Project: Cassandra > Issue Type: Improvement > Components: Legacy/CQL > Reporter: Sylvain Lebresne > Assignee: patrick lee > Priority: Low > Labels: AdventCalendar2021, lhf > Fix For: 4.x > > > People sometimes run into issues with schema, and that is often because they > do concurrent schema changes, which are just not supported and we should fix > that someday, but in the meantime, it's not always easy to even check if you > may indeed have had concurrent schema changes. > A very trivial way to make that easier would be to simply log DDL statements > on the coordinator before they are executed. This is likely useful info for > operators in the first place, and would allow in most case to track if > concurrent schema was the likely cause of a particular issue seen. > +Additional info for newcomers:+ > In order to implement this change you will need to modify > {{org.apache.cassandra.cql3.QueryProcessor}} to log the schema change before > it is executed. -- This message was sent by Atlassian Jira (v8.20.1#820001) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
