Technical notes
- A Charmed Apache Kafka cluster is secure by default, meaning that when deployed if there are no client charms related to it, external listeners will not be enabled.
- We recommend deploying one
data-integrator
withextra-user-roles=admin
alongside the Apache Kafka deployment, in order to enable listeners and also create one user with elevated permission to perform administrative tasks. For more information, see the How-to manage application guide. - The current release has been tested with Juju 2.9.45+ and Juju 3.1+
- Inplace upgrade for charms tracking
latest
is not supported, both for Apache ZooKeeper and Apache Kafka charms. Perform data migration to upgrade to a Charmed Apache Kafka cluster managed via a3/stable
charm. For more information on how to perform the migration, see How-to migrate a cluster guide.
