Benjamin Lerer reassigned CASSANDRA-11307: ------------------------------------------ Assignee: Benjamin Lerer > Inappropriate WARN log message for commit log sync delay when using > commitlog_sync: batch > ----------------------------------------------------------------------------------------- > > Key: CASSANDRA-11307 > URL: https://issues.apache.org/jira/browse/CASSANDRA-11307 > Project: Cassandra > Issue Type: Bug > Components: Core > Environment: Linux > Reporter: Gary Ogasawara > Assignee: Benjamin Lerer > Priority: Minor > > In v2.1.11 when using configuration > commitlog_sync: batch > commitlog_sync_batch_window_in_ms: 2 > will frequently get this WARN log though there is not a real problem. > WARN [COMMIT-LOG-WRITER] 2016-03-03 00:40:11,646 > AbstractCommitLogService.java:105 - Out of 142412 commit log syncs over the > past 300s with average duration of 0.00ms, 35 have exceeded the configured > commit interval by an average of 3.66ms > WARN [COMMIT-LOG-WRITER] 2016-03-03 00:45:11,755 > AbstractCommitLogService.java:105 - Out of 104605 commit log syncs over the > past 300s with average duration of 1.74ms, 18314 have exceeded the configured > commit interval by an average of 6.33ms > Looks like BatchCommitLogService sets AbstractCommitLogService() > pollIntervalMillis to the configured commitlog_sync_batch_window_in_ms. > Since CASSANDRA-9504, this is by default set to 2 which causes this WARN > message to be triggered unnecessarily. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
