Chapter 144. AutoRestart schema reference
Chapter 144. AutoRestart schema reference Used in: KafkaConnectorSpec , KafkaMirrorMaker2ConnectorSpec Full list of AutoRestart schema properties Configures automatic restarts for connectors and tasks that are in a FAILED state. When enabled, a back-off algorithm applies the automatic restart to each failed connector and its tasks. An incremental back-off interval is calculated using the formula n * n + n where n represents the number of restarts. This interval is capped at a maximum of 60 minutes. Consequently, a restart occurs immediately, followed by restarts after 2, 6, 12, 20, 30, 42, 56 minutes, and then at 60-minute intervals. By default, Streams for Apache Kafka initiates restarts of the connector and its tasks indefinitely. However, you can use the maxRestarts property to set a maximum on the number of restarts. If maxRestarts is configured and the connector still fails even after the final restart attempt, you must then restart the connector manually. For Kafka Connect connectors, use the autoRestart property of the KafkaConnector resource to enable automatic restarts of failed connectors and tasks. Enabling automatic restarts of failed connectors for Kafka Connect apiVersion: kafka.strimzi.io/v1beta2 kind: KafkaConnector metadata: name: my-source-connector spec: autoRestart: enabled: true If you prefer, you can also set a maximum limit on the number of restarts. Enabling automatic restarts of failed connectors for Kafka Connect with limited number of restarts apiVersion: kafka.strimzi.io/v1beta2 kind: KafkaConnector metadata: name: my-source-connector spec: autoRestart: enabled: true maxRestarts: 10 For MirrorMaker 2, use the autoRestart property of connectors in the KafkaMirrorMaker2 resource to enable automatic restarts of failed connectors and tasks. Enabling automatic restarts of failed connectors for MirrorMaker 2 apiVersion: kafka.strimzi.io/v1beta2 kind: KafkaMirrorMaker2 metadata: name: my-mm2-cluster spec: mirrors: - sourceConnector: autoRestart: enabled: true # ... heartbeatConnector: autoRestart: enabled: true # ... checkpointConnector: autoRestart: enabled: true # ... 144.1. AutoRestart schema properties Property Property type Description enabled boolean Whether automatic restart for failed connectors and tasks should be enabled or disabled. maxRestarts integer The maximum number of connector restarts that the operator will try. If the connector remains in a failed state after reaching this limit, it must be restarted manually by the user. Defaults to an unlimited number of restarts.
