Summary: SEPExecutor local requests not triggered often Key: CASSANDRA-15022 URL: https://issues.apache.org/jira/browse/CASSANDRA-15022 Project: Cassandra Issue Type: Improvement Reporter: Marcus Olsson Based on observations done in [CASSANDRA-14983|https://issues.apache.org/jira/browse/CASSANDRA-14983?focusedCommentId=16745238&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-16745238] SEPExecutor#maybeExecuteImmediately() does not necessarily run tasks in the same thread often. The logic [as it is today|https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/concurrent/SEPExecutor.java#L166] basically requires another task to be in the work queue for it to trigger. One option to make it trigger more often could be to change the logic to: {code:java} if (workPermits == 0 || (takeTaskPermit && taskPermits == 0)) return false; {code} So that we only check the taskPermits if we want to take a taskPermit. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
