Summary: Increased Read Latency With Cassandra >= 3.11.7 Key: CASSANDRA-16465 URL: https://issues.apache.org/jira/browse/CASSANDRA-16465 Project: Cassandra Issue Type: Bug Reporter: Ahmed ELJAMI After upgrading Cassandra from 3.11.3 to 3.11.9, Cassandra read latency 99% increased significantly. Getting back to 3.11.3 immediately fixed the issue. I have observed "SStable reads" increases after upgrading to 3.11.9. The same behavior was observed by some other users: [https://www.mail-archive.com/user@cassandra.apache.org/msg61247.html] According to Paulo Motta's comment, this behavior may be caused by https://issues.apache.org/jira/browse/CASSANDRA-15690 which was introduced on 3.11.7 and removed an optimization that may cause a correctness issue when there are partition deletions. -- 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
