      Aiven for Apache Kafka®

    New Quick connect experience for Aiven for Apache Kafka®

    Quick connect for Aiven for Apache Kafka® is now a single-page guided flow. It replaces the previous multi-step setup flow, reducing the steps needed to connect Kafka clients and tools.

    The updated flow brings topic setup, authentication, permissions, generated code, and project templates into one place, making it easier to test your service and start producing and consuming messages.

    For more information, see Connect to Aiven for Apache Kafka®.

    Switch classic Kafka topics to diskless topics (early availability)

    You can now switch an existing classic topic in Aiven for Apache Kafka® to a diskless topic without copying data or renaming the topic.

    The topic remains available during the switch. Records written before the switch remain readable from the classic topic log. Records written after the switch are stored in the diskless topic.

    Topics can be switched using the Aiven CLI or Aiven API. This feature is in early availability and is not enabled by default. To request access, contact your account team.

    To learn more, see Switch a classic topic to a diskless topic.

    Improved

    • REST proxy can forward inbound OIDC bearer tokens to Schema Registry.
    • Schema Registry separates OIDC authentication and authorization for finer access control.

    Fixed

    • Fixed JSON Schema compatibility checks that use anyOf with type array shorthand.

    For more information, see the Karapace 6.2.0 release notes.

    Create diskless topics automatically with regular expressions

    You can now configure Aiven for Apache Kafka® to create new topics as diskless topics automatically when their names match regular expressions you configure. Use this feature when clients or tools can't set diskless.enable=true, reject unknown topic configurations, or create topics dynamically, such as Kafka Connect CDC connectors and MirrorMaker 2.

    Set up to 32 regular expressions in kafka_diskless.auto_diskless_topic_regexes using the Aiven API or Aiven CLI. Regular expressions apply only to new topics. Existing topics keep their current type, and internal Kafka topics and compacted topics are excluded.

    For more information, see Create diskless topics automatically using regular expressions.

    Cross-cluster replication for Aiven for OpenSearch® (limited availability)

    Aiven for OpenSearch® now supports cross-cluster replication (CCR). This feature is in limited availability. Contact Aiven to request access.
    CCR lets you replicate indices, mappings, and metadata from a leader cluster to one or more follower clusters across regions or cloud providers. Use it to place data closer to your users for lower query latency and to spread query-heavy workloads across follower clusters for better availability.
    Set up CCR from the Cross cluster replication section on the service Overview page in the Aiven Console or with the Aiven API. You can promote an existing OpenSearch service to a follower or create a new one. This sets up the connection between the follower and the leader. Then you start replication from the follower using the OpenSearch replication APIs either per index or with an auto-follow rule that replicates every index matching a pattern. See Set up cross-cluster replication for Aiven for OpenSearch® for details.

    Audit logging for Aiven for Apache Kafka®

    You can now enable and configure audit logging for Aiven for Apache Kafka® services from your service configuration.

    Audit logging records Kafka client activity to help support security reviews and compliance workflows. Audit logs can include authenticated activity, unauthenticated access attempts, and allowed or denied Kafka operations, depending on the configuration.

    Enabling or updating audit logging causes a rolling restart of the Kafka brokers in the service.

    For more information, see Audit logging for Aiven for Apache Kafka®.
