---------------------------------------
Summary: Make PeriodicCommitLogService.blockWhenSyncLagsNanos
configurable
Key: CASSANDRA-14580
URL: https://issues.apache.org/jira/browse/CASSANDRA-14580
Project: Cassandra
Issue Type: Improvement
Reporter: Jason Brown
Assignee: Jason Brown
Fix For: 4.0
When using the default values for periodic commitlog, the sync is every ten
seconds and if there's a lad in flushing to disc, we can block for up to 15
seconds (sync time * 1.5). However, if you lower the sync time to 1 second, for
example, the block time is only 1.5 seconds (not acceptable in all situations).
Admittedly this is only an expert-level setting, but useful in some cases.
