Create and manage Aiven for Apache Kafka® MirrorMaker 2 replication flows

Commands for managing Aiven for Apache Kafka® MirrorMaker 2 replication flows.

avn mirrormaker replication-flow create

Creates a new Aiven for Apache Kafka® MirrorMaker 2 replication flow.

warning

Before creating a replication flow, an integration needs to be created between the Aiven for Apache Kafka MirrorMaker 2 service and each of the source and the target services.

for example, An integration with alias kafka-target-alias between an Aiven for Apache Kafka service named kafka-target and an Aiven for Apache Kafka MirrorMaker 2 named kafka-mm can be created with:

avn service integration-create \
  -s kafka-target              \
  -d kafka-mm                  \
  -t kafka_mirrormaker         \
  -c cluster_alias=kafka-target-alias

At most one replication flow can be build between any two Aiven for Apache Kafka services.

Parameter	Information
service_name	The Aiven for Apache Kafka MirrorMaker 2 service where to create the replication flow
--source-cluster	The Aiven for Apache Kafka service to be used as source for replication
--target-cluster	The Aiven for Apache Kafka service to be used as target for replication
replication_flow_config	JSON string or path (preceded by @) to a JSON configuration file for the replication flow definition

Example: In the service kafka-mm create a new replication flow from an Aiven for Apache Kafka service with integration alias kafka-source-alias to a service named kafka-target-alias with the following settings:

• include all topics with name starting with my-src-topic (topic name patterns can be defined using Java patterns)
• exclude all topics with name ending with not-include
• DefaultReplicationPolicy as replication policy class
• enable MirrorMaker 2 heartbeats
• enable synching of consumer groups offset every 60 seconds

avn mirrormaker replication-flow create kafka-mm \
  --source-cluster kafka-source-alias \
  --target-cluster kafka-target-alias \

            ".*not-include"
        ]
    }
  '

avn mirrormaker replication-flow delete

Deletes an existing Aiven for Apache Kafka® MirrorMaker 2 replication flow.

Parameter	Information
service_name	The Aiven for Apache Kafka MirrorMaker 2 service where to delete the replication flow
--source-cluster	The Aiven for Apache Kafka service to be used as source for replication
--target-cluster	The Aiven for Apache Kafka service to be used as target for replication

Example: In the service kafka-mm delete the replication flow from an Aiven for Apache Kafka service with integration alias kafka-source-alias to the service named kafka-target-alias.

avn mirrormaker replication-flow delete kafka-mm \
  --source-cluster kafka-source-alias \
  --target-cluster kafka-target-alias

avn mirrormaker replication-flow get

--source-cluster	The Aiven for Apache Kafka service to be used as source for replication
--target-cluster	The Aiven for Apache Kafka service to be used as target for replication

Example: In the service kafka-mm retrieve the details of the replication flow from an Aiven for Apache Kafka service with integration alias kafka-source-alias to the service named kafka-target-alias.

avn mirrormaker replication-flow get kafka-mm \
  --source-cluster kafka-source-alias \
  --target-cluster kafka-target-alias

An example of the avn mirrormaker replication-flow get command output:

    "topics.blacklist": [
        ".*not-include"
    ]
}

avn mirrormaker replication-flow list

Lists the configuration details for all replication flows defined in an existing Aiven for Apache Kafka® MirrorMaker 2 service.

Parameter	Information
service_name	The Aiven for Apache Kafka MirrorMaker 2 service where to list the replication flow

Example: List the configuration details for all replication flows defined in an existing Aiven for Apache Kafka MirrorMaker 2 named kafka-mm.

avn mirrormaker replication-flow list kafka-mm
