    Aiven for Apache Kafka®

    KRaft mode now generally available

    KRaft (Kafka Raft metadata mode) is now generally available in Aiven for Apache Kafka®. All new services using Apache Kafka 3.9 and later run in KRaft mode by default, replacing ZooKeeper for metadata management.

    Key considerations

    • Migration from ZooKeeper to KRaft for existing services is not yet available. Support will be added later.
    • Kafka 3.8 support is extended by one year to support transition planning.
    • Startup-4 replaces Startup-2 plans in Apache Kafka 3.9 and later. All feature restrictions from Startup-2 also apply to Startup-4, including Datadog restrictions.
    • Some controller metrics are no longer available in KRaft mode.
    • Existing clients and integrations such as Kafka Connect, MirrorMaker 2, and Karapace continue to work without changes.

    For details, see KRaft mode and Transitioning to KRaft.

    Aiven Terraform provider

    Aiven Provider for Terraform version 4.42.0 now available

    This version of the Aiven Terraform Provider supports Diskless Topics for Aiven for Apache Kafka® services. For BYOC services that have access to the this feature, the config.inkless_enable field in aiven_kafka_topic resource enables diskless.

    This release also includes fixes for the following:

    • project_vpc_id can now be set to null. When upgrading, verify your service VPC settings are correct as services without this field will be deployed to the public internet.
    • The aiven_clickhouse_grant resource no longer attempts to manage or interfere with privileges granted on ClickHouse named collections, preventing errors when grants are managed externally.

    In addition, several new fields have been added or updated. For more details on these fixes and updates, view the complete Aiven Provider for Terraform changelog.
