Hi Husna,

The trouble with cross cluster Kafka use is unpredictable network latency.
If a consumer encounters high latency, it will just lag, but (hopefully)
eventually it will catch up.  If a producer encounters high latency, it
will have to buffer messages locally until those messages are ACKed by the
Kafka cluster.  If the buffer gets too full, it will have to start dropping
