Summary: Update generations and update comments for altered distributed system keyspaces Key: CASSANDRA-15454 URL: https://issues.apache.org/jira/browse/CASSANDRA-15454 Project: Cassandra Issue Type: Bug Components: Cluster/Schema Reporter: Aleksey Yeschenko Assignee: Aleksey Yeschenko In 4.0, we set {{memtable_flush_period_in_ms}} to 0 (from 1 hour previously), and changed default chunk length from 64KiB to 16KiB. On startup we would try to override existing schema definitions for {{system_traces}}, {{system_distributed}}, and {{system_auth}} to reflect these changes, but because these are changes to smaller values, while timestamps remain the same, these will never override existing, pre-upgrade values from 3.0 or 3.11. As a result, a schema migration request will be pushed by a node on every bounce to every replica, causing unnecessary and ultimately fruitless work. Bumping the generations fixes the issue, and documenting the changes doesn't hurt either. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
