Additionally, each independent Kafka Bridge instance must have a replica. The example configuration above will result in the following JVM options: The jvmOptions section also allows you to enable and disable garbage collector (GC) logging. Kafka Connect clusters can run multiple of nodes. AMQ Streams can configure Kafka to use TLS (Transport Layer Security) to provide encrypted communication between Kafka brokers and clients either with or without mutual authentication.

Authentication and Authorization", Collapse section "3.1.6.1. Using a managed Kafka service is a sensible choice if you are not already running Kafka in production. This enables you to plan when to apply changes to a Kafka resource to minimize the impact on Kafka client applications. Authentication", Collapse section "3.1.6.3. The only other services running on such nodes will be system services such as log collectors or software defined networks. Certificate Authorities", Collapse section "8.1. The primary way of increasing throughput for a topic is to increase the number of partitions for that topic. Consumer options are listed in Apache Kafka documentation. The certificate is specified in the certificateAndKey property and is always loaded from an OpenShift secret. In this case, the secret containing the certificate has to be configured in the KafkaMirrorMaker.spec.producer.tls property. Unless TLS encryption was disabled, extract the public certificate of the broker certification authority. An example of listeners property with all listeners enabled, An example of listeners property with only the plain listener enabled. Configuring TLS in Kafka Connect, 3.3.4. When a Healthcheck probe fails, OpenShift assumes that the application is not healthy and attempts to fix it. If the throttle is too low then the newly assigned brokers will not be able to keep up with records being published and the reassignment will never complete.

In this example, the default storage class is named my-storage-class: Example AMQ Streams cluster using storage class overrides. For example: By default, Kafka Connect will try to connect to Kafka brokers without authentication. The server and client each generate a new challenge for each authentication exchange. Default is 15 seconds. Edit the whitelist property in the KafkaMirrorMaker resource. By default, AMQ Streams tries to automatically determine the hostnames and ports that your Kafka cluster advertises to its clients. The values can be one of the following JSON types: The Cluster Operator does not validate keys or values in the config object provided. The certificates should be stored in X.509 format. A Kafka Bridge instance has its own state which is not shared with another instances. When using Kafka Connect with a Kafka cluster not managed by AMQ Streams, you can specify the bootstrap servers list according to the configuration of the cluster. Persistent storage supports additional configuration options: Increasing the size of persistent volumes in an existing AMQ Streams cluster is only supported in OpenShift versions that support persistent volume resizing. Scheduling pods to specific nodes", Expand section "3.1.19.3. For example, in a cluster of 12 brokers the pods are named cluster-name-kafka-0 up to cluster-name-kafka-11. Upgrading Kafka Mirror Maker resources, 12. These options are automatically configured in case they are not present in the KafkaConnect.spec.config or KafkaConnectS2I.spec.config properties. For example: You can increase the throughput in mirroring topics by increase the number of consumer threads. You can customize the advertised hostname and port in the overrides property of the external listener. Avoid critical applications to share the node, 3.4.14.1.3. If you need to change the throttle during reassignment you can use the same command line with a different throttled rate. Configuring the image property in other resources, 3.3.12.1.

If you need to change the images used for different versions of Kafka, it is better to configure the Cluster Operators STRIMZI_KAFKA_IMAGES environment variable. Container image which should be used for given components can be specified using the image property in: The Kafka.spec.kafka.image property functions differently from the others, because AMQ Streams supports multiple versions of Kafka, each requiring the own image. Once built, container images are stored in OpenShifts local container image repository and are available for use in deployments. Users can add or remove volumes from the JBOD configuration. AMQ Streams allows you to configure some of these options. [Question] Kafka data auto deletes every one day (using default strimzi configurations).

For more information on GC, see Section3.3.10.1, JVM configuration. The following example configures a single maintenance time window that starts at midnight and ends at 01:59am (UTC), on Sundays, Mondays, Tuesdays, Wednesdays, and Thursdays: In practice, maintenance windows should be set in conjunction with the Kafka.spec.clusterCa.renewalDays and Kafka.spec.clientsCa.renewalDays properties of the Kafka resource, to ensure that the necessary CA certificate renewal can be completed in the configured maintenance time windows. The logLevel property is used to specify the logging level. Producer options are listed in Apache Kafka documentation. CPU and memory resources", Collapse section "3.4.9. In such a case, you should either copy the AMQ Streams images or build them from the source. Each listener can have a different networkPolicyPeers configuration. Strimzi Administrators", Expand section "3. That can lead to performance degradation. Designating Strimzi Administrators, 3.1.1.1. For example: By default, Kafka Connect tries to connect to Kafka brokers using a plain text connection. You can specify the label using either the built-in node label like beta.kubernetes.io/instance-type or custom labels to select the right node. KafkaBridgeAuthenticationPlain schema reference, C.98. Instead the client and the server are each challenged by the other to offer proof that they know the password of the authenticating user. For example: Kafka Connect has its own configurable loggers: Garbage collector (GC) logging can also be enabled (or disabled).
