MirrorMaker has always been a little flaky (requiring manual restarts to get proper partition rebalance assignment, etc.), but is being especially so when replicating from the 0.9 main Kafka cluster to the new 1.0 jumbo Kafka cluster. Other's have also experienced this MirrorMaker flakiness. We should try out other options and consider switching, especially since T189464 now blocks the Kafka jumbo migration tasks.
- Uber's uReplicator
- open source
- Kafka 0.10 client (should be ok)
- Confluent Replicator
- Closed sourced, but still free
- Just a Kafka Connect connector
- Latest Kafka, backed by Confluent
