    Aiven for Apache Kafka®

    Sample data generator for Aiven for Apache Kafka

    You can now generate sample Kafka data directly from the Aiven Console to test and explore your service setup. The generator creates a Kafka topic, applies a predefined Avro schema, and produces test messages for up to 4 hours. No client setup or code is required.

    Use the generator to:

    • Choose from sample scenarios, such as logistics, user activity, or metrics
    • Start streaming data within seconds of service creation
    • View messages and schema details in the Aiven Console
    • Stop the stream from the browser tab where it was started

    Only one sample stream can run per service at a time. This feature is available at no additional cost and does not use service credits.
    For more information, see Stream sample data from the Aiven Console.

    Aiven for Apache Kafka® Connect

    Stream Reactor has been updated to version 9.0.2

    Stream Reactor, a collection of Apache Kafka Connect connectors, has been updated to version 9.0.2. This release includes compatibility updates and internal improvements. Key changes include the following:

    • Connector class names and converter package names have been standardized. Update configurations if they reference “com.datamountaineer” packaged class names.
    • StreamReactor 9.x incorporates class name changes introduced in version 6.0.0 by Lenses. These changes make version 9.x incompatible with version 4.2.0 previously offered by Aiven.
    • When upgrading from 4.2.0 to 9.x, recreate the connectors using the updated class names, as existing ones will not work with the new version. For details, see All connectors (6.x).
    • To maintain compatibility and safe migration to 9.0.1, first pin the connector version to 4.2.0. For instructions, see Manage connector versions.

    For more information, see the Stream Reactor release notes. For a list of supported Stream Reactor connectors in Aiven, see the list of connector plugins.

    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.
