Summary

Confluent offers two approaches to multi-datacenter replication: Multi-Region Clusters and Confluent Replicator, which can be used for both single-cluster and multi-cluster deployments. Multi-Region Clusters are a single cluster spanning multiple datacenters, while Confluent Replicator operates on two separate clusters. Confluent Replicator provides a high-performance and resilient way to copy topic data between clusters. It enables bidirectional replication, fan-out, and reduces the number of public communication channels between hybrid cloud environments. Confluent Control Center integrates with Kafka Connect, enabling the creation and management of connectors, including Replicator, using a graphical interface. The control center provides detailed monitoring for Replicator, ensuring efficient replication flows. Replicator includes features such as offset translation, cyclic replication prevention through provenance headers, and topic synchronization to ensure consistent configuration state between source and destination clusters. It can be deployed into existing Kafka Connect clusters or run as a standalone process with fault tolerance and load distribution capabilities.
