Summary: Update commitlog_sync_period for modern hardware
Key: CASSANDRA-20508
URL: https://issues.apache.org/jira/browse/CASSANDRA-20508
Project: Apache Cassandra
Issue Type: Improvement
Components: Local/Commit Log
Reporter: Jon Haddad
We've used {{commitlog_sync_period: 10000ms}} as long as I can remember. I
think the original setting of 10 seconds made sense when spinning disks were
the norm, but now that they're the outlier we should update this to be more
appropriate for modern hardware. I generally lower this to 2000ms when using
disaggregated storage, and have heard some folks use sub second for NVMe, but
haven't done it myself. I think as a default, we can safely bring this down to
2 seconds.
