"""
@jira_ticket CASSANDRA-9560
Test that changes to the DURABLE_WRITES option on keyspaces is
respected in subsequent writes.
This test starts by writing a dataset to a cluster and asserting that
the commitlogs have been written to. The subsequent test depends on
the assumption that this dataset triggers an fsync.
After checking this assumption, the test destroys the cluster and
creates a fresh one. Then it tests that DURABLE_WRITES is respected by:
- creating a keyspace with DURABLE_WRITES set to false,
- using ALTER KEYSPACE to set its DURABLE_WRITES option to true,
- writing a dataset to this keyspace that is known to trigger a commitlog fsync,
- asserting that the commitlog has grown in size since the data was written.
