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.
> Please refer to the communication in the mailing list.
