Enable automatic restart for Apache Kafka® Connect connectors

Automatic restart can help recover a connector task after a rare transient failure, such as an out-of-memory error caused by a sudden data surge.

Before you enable automatic restart, investigate the cause of the connector failure. Automatic restart is not recommended for recurring failures because the connector might continue to fail until the underlying issue is fixed.

note

In some cases, the Debezium source connector for PostgreSQL® can stop after PostgreSQL maintenance if PostgreSQL cannot create replication slots before failover. Automatic restart can help recover the connector in this scenario.

Enable automatic restart in the Aiven Console​

All Aiven-managed Apache Kafka Connect connectors support automatic restart.

To enable automatic restart for an existing connector:

  1. In the Aiven Console, select the Aiven for Apache Kafka or Aiven for Apache Kafka Connect service where the connector is defined.
  2. Select Manage stream > Connectors from the sidebar.
  3. Open the connector to update.
  4. Select the Aiven tab.
  5. For Automatic restart, select True.

After you enable automatic restart, the connector restarts automatically when a failure is detected.

warning

Automatic restart restarts the entire connector, not only the failed tasks.
