Red Hat SummitChapter 4. Technology Previews
Technology Preview features included with Streams for Apache Kafka 2.7.
Technology Preview features are not supported with Red Hat production service-level agreements (SLAs) and might not be functionally complete; therefore, Red Hat does not recommend implementing any Technology Preview features in production environments. This Technology Preview feature provides early access to upcoming product innovations, enabling you to test functionality and provide feedback during the development process. For more information about the support scope, see Technology Preview Features Support Scope.
4.1. KRaft mode
KRaft mode is available as a technology preview.
Currently, the KRaft mode in Streams for Apache Kafka has the following limitations:
- Downgrading from KRaft mode to using ZooKeeper is not supported.
- JBOD storage with multiple disks is not supported.
- Unregistering Kafka nodes removed from the Kafka cluster.
4.2. Kafka Static Quota plugin configuration
Use the technology preview of the Kafka Static Quota plugin to set throughput and storage limits on brokers in your Kafka cluster. You can set a byte-rate threshold and storage quotas to put limits on the clients interacting with your brokers.
Example Kafka Static Quota plugin configuration
client.quota.callback.class= io.strimzi.kafka.quotas.StaticQuotaCallback
client.quota.callback.static.produce= 1000000
client.quota.callback.static.fetch= 1000000
client.quota.callback.static.storage.soft= 400000000000
client.quota.callback.static.storage.hard= 500000000000
client.quota.callback.static.storage.check-interval= 5See Setting limits on brokers using the Kafka Static Quota plugin.
