Description

"commitlog_sync_batch_window_in_ms" doesn't seem to be working at least in the latest versions in 2.1.16, 2.2.8 and 3.9.

Here is the way to reproduce the bug.

1. set the following parameters in cassandra.yaml

• commitlog_sync: batch
• commitlog_sync_batch_window_in_ms: 10000 (10s)
  2. issue an insert from cqlsh
  3. it immediately returns instead of waiting for 10 seconds.
