Confluent Replicator

Confluent Replicator allows you to easily and reliably replicate topics from one Apache Kafka® cluster to another. In addition to copying the messages, this connector will create topics as needed preserving the topic configuration in the source cluster. This includes preserving the number of partitions, the replication factor, and any configuration overrides specified for individual topics.

The Replicator Connector supports replication in the context of several use cases, including:

Features

Replicator supports the following features:

  • Topic selection using whitelists, blacklists, and regular expressions.
  • Dynamic topic creation in the destination cluster with matching partition counts, replication factors, and topic configuration overrides.
  • Automatic resizing of topics when new partitions are added in the source cluster.
  • Automatic reconfiguration of topics when topic configuration changes in the source cluster.
