Chapter 1. Features

AMQ Streams now supports Kafka 2.2.1.

You must upgrade the Cluster Operator to 1.2 before you can upgrade to Kafka 2.2.1. For instructions, see AMQ Streams and Kafka upgrades.

After you have performed an upgrade, custom resources that use kafka.strimzi.io/v1alpha1 must be updated as the API version is deprecated.

Refer to the Kafka 2.2.0 and Kafka 2.2.1 Release Notes for additional information.

As a requirement for the new features, AMQ Streams now supports OpenShift Container Platform 3.11 and 4.x.

OpenShift Container Platform 3.9 and 3.10 is no longer supported.

AMQ Streams can be installed on OpenShift 4.x:

The YAML files describing the CRDs provided with AMQ Streams now support multiple versions. The change means that there is now support for a schema specific to an API version.

See Custom resources

It is now possible to add or remove volumes from JBOD storage to respond to new requirements for storing data. To make the change, the volumes spec for the Kafka resource is edited and updated. Following the update, new topics can be assigned to the disks or existing partitions can be reassigned.

See Removing volumes from JBOD storage

To respond to an increased demand for storage, you can now increase the size of the persistent volumes used for the storage of messages and logs in an existing AMQ Streams cluster.

A persistent volume can be resized if:

Persistent volume size is defined in the size field in the spec.kafka.storage and spec.zookeeper.storage properties:

apiVersion: kafka.strimzi.io/v1beta1
kind: Kafka
metadata:
  name: my-cluster
spec:
  kafka:
    # ...
    storage:
      type: persistent-claim
      size: 2000Gi
      class: my-storage-class
    # ...
  zookeeper:
    # ...

apiVersion: kafka.strimzi.io/v1beta1
kind: Kafka
metadata:
  name: my-cluster
spec:
  kafka:
    # ...
    storage:
      type: persistent-claim
      size: 2000Gi
      class: my-storage-class
    # ...
  zookeeper:
    # ...
