    • Aiven Terraform provider

    Aiven Provider for Terraform version 4.49.0 now available

    This version of the Aiven Terraform Provider introduces a new aiven_service_list data source that lets you list all services in a project, making service discovery and management easier.


    Other notable improvements in this release:

    • Enhanced Kafka topic handling with retry logic for 404 errors from the KafkaTopicListV2 endpoint
    • Added mysql_user_config.migration.reestablish_replication field for Aiven for MySQL services to skip dump-restore and start replication directly
    • Improved error handling for resources that weren't properly removing from state when deleted externally

    Additionally, the termination_protection field for aiven_mysql_database has been deprecated in favor of using Terraform's built-in prevent_destroy lifecycle rule.

    Enforce allowed URLs for SASL OAUTHBEARER authentication

    Aiven for Apache Kafka now enforces an allowed list of URLs for SASL OAUTHBEARER authentication to address CVE-2025-27817.

    By default, the value from sasl_oauthbearer_jwks_endpoint_url is added automatically to the allowed list. You can explicitly allow additional URLs by setting sasl_oauthbearer_allowed_urls.

    URLs that are not included in either sasl_oauthbearer_allowed_urls or sasl_oauthbearer_jwks_endpoint_url are now blocked for SASL OAUTHBEARER authentication.

    Although Apache Kafka Connect and Apache Kafka MirrorMaker 2 do not officially support SASL OAUTHBEARER, this change prevents unsupported configurations from bypassing security controls.

    • Aiven for Valkey™

    Aiven for Valkey™ clustering: out now in limited availability

    We are excited to announce the launch of Aiven for Valkey™ clustering in limited availability. This managed solution provides scalable, distributed in-memory data storage with built-in high availability.

    Aiven for Valkey clustering automatically partitions your data across multiple nodes (shards), enabling you to handle larger datasets and higher traffic loads than a single-node deployment.

    Key benefits:

    • High availability: Automatic failover, minimal downtime, and replica promotion to maintain service continuity during unexpected failures or maintenance.
    • Scalability & performance: Distribute read and write operations across multiple shards for significantly higher throughput, lower latency, and better load distribution.
    • Compatibility: Fully compatible with existing Valkey cluster-aware client libraries for seamless integration with current applications.
    • Flexible sizing: Supports various instance sizes, including smaller 4 GB RAM instances, allowing for better cost optimization.

    Learn more in the Aiven for Valkey™ clustering documentation.
