Ioan Eugen Stan commented on JAMES-2605: ---------------------------------------- Is this still an issue? I read some performance benchmarks you guys did and it seemed to work just fine now. Can we close the issue? > Cassandra MailQueue implementation has a 20% fail rate on load > -------------------------------------------------------------- > > Key: JAMES-2605 > URL: https://issues.apache.org/jira/browse/JAMES-2605 > Project: James Server > Issue Type: Bug > Components: cassandra > Reporter: Matthieu Baechler > Priority: Major > > RabbitMQ + Cassandra implementation of Mailqueue proved to be brittle, we > have around 20% error rate for SMTP mail delivery under heavy load. > It's probably linked to the heavy use of parallelism into Cassandra Mailqueue > code that can submit an unbounded numer of request for a single Mailqueue > operation. > > We should try to remove this unbounded parallelism and check the failure rate > under load. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: server-dev-unsubscr...@james.apache.org For additional commands, e-mail: server-dev-h...@james.apache.org
