Alex Petrov updated CASSANDRA-19517: ------------------------------------ Test and Documentation Plan: Includes tests. Additional stress testing will be done during release qualification. Status: Patch Available (was: Open) > Raise priority of TCM internode messages during critical operations > ------------------------------------------------------------------- > > Key: CASSANDRA-19517 > URL: https://issues.apache.org/jira/browse/CASSANDRA-19517 > Project: Cassandra > Issue Type: Improvement > Components: Transactional Cluster Metadata > Reporter: Alex Petrov > Assignee: Alex Petrov > Priority: Normal > Attachments: ci_summary.html, result_details.tar.gz > > > In a busy cluster, TCM messages may not get propagated throughout the > cluster, since they will be ordered together with other P1 messages (for > {{TCM_}} prefixed verbs), and with P2 with all Paxos operations. > To avoid this, and make sure we can continue cluster metadata changes, all > {{TCM_}}-prefixed verbs should have {{P0}} priority, just like Gossip > messages used to. All Paxos messages that involve distributed metadata > keyspace should now get an {{URGENT}} flag, which will instruct internode > messaging to schedule them on the {{URGENT_MESSAGES}} connection. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
