Aleksey Yeschenko commented on CASSANDRA-16465: ----------------------------------------------- [~paulo] Yes, we could easily - whether or not it is the cause of this JIRA. > 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 > Components: Legacy/Local Write-Read Paths > Reporter: Ahmed ELJAMI > Priority: Normal > Fix For: 3.11.11 > > > 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
