Description

We only use the code path added in CASSANDRA-12268 for the view builder because otherwise we would break the contract of the batchlog, where some mutations may be written and pushed out before the whole batch log has been saved.

We would need to ensure that all of the updates make it to the batchlog before allowing the batchlog manager to try to replay them, but also before we start pushing out updates to the paired replicas.
