One possible reason is that with a consumer reading messages as they are
published, it's sometimes possible for the consumer to consume and ack the
message before it's written to the persistent store, which eliminates the
need to write it at all and eliminates the need to read it from the
persistent store prior to dispatching it to the consumer.
