Improvement of Apache Kafka Mirrormaker

uReplicator

Update

From 11/20/2018, old master branch (no uReplcator-Manager module) is moved to branch-0.1. New master is backward-compatible and supports both non-federation and federation mode.

Highlight

uReplicator provides a Kafka replication solution with high performance, scalability and stability.

uReplicator is good at:

• High throughput
  • uReplicator has a controller to assign partitions to workers based on throughput in source cluster so each worker can achieve max throughput. (Currently it depends on Chaperone; We will make it get workload from JMX shortly)
  • uReplicator checks lags on each worker and removes heavy traffic from lagging workers.
• High availability
  • uReplicator uses smart rebalance instead of high level consumer rebalance which can guarantee smooth replication.
• High scalability
  • When the scale of Kafka infrastructure increases, simply add more hosts to uReplicator and it will scale up automatically
• Smart operation (Federated uReplicator)
  • Federated uReplicator can set up replication route automatically.
  • When a route has higher traffic or lag, Federated uReplicator can add workers automatically and release afterwards.
  • uReplicator can detect new partitions in source cluster and start replication automatically
