Set up an Apache Kafka® MirrorMaker 2 replication flow

Apache Kafka® MirrorMaker 2 replication flows enable the topics sync from a source Apache Kafka® cluster to a target Apache Kafka cluster deployed anywhere in the world. Replication flows can be defined against Aiven for Apache Kafka services or external Apache Kafka clusters.

To define a replication flow between a source Apache Kafka cluster and a target cluster:

1. Log in to the Aiven Console and select the Aiven for Apache Kafka MirrorMaker 2 service where you want to define the replication flow.

   note

   If no Aiven for Apache Kafka MirrorMaker 2 are already defined, you can create one in the Aiven console.

2. In the service Overview screen, scroll to the Service integrations section and select Manage integrations.

3. If there is no integration for the source/target Apache Kafka cluster, set up the necessary integrations:

   • On the Integrations screen, choose the desired integration from the list for the source Apache Kafka cluster.
   • Select an existing Apache Kafka service to use as the source/target for the replication flow.
   • Provide a cluster alias name (for example,, source-Kafka) to the integration of the Apache Kafka cluster.
   • Repeat the above steps to set up the integration for the target Apache Kafka cluster and provide a cluster alias name.

4. Once that the source and target Apache Kafka clusters are configure, select Replication flows from the left sidebar.

5. Select Create replication flow.

6. On the Create new replication flow screen, define the replication source and target cluster, the list of topics to be included or excluded and the sync settings.

7. Select Create.

8. In the target Apache Kafka cluster, verify the replicated topics with the topic name source-cluster-alias.source-topic-name.
