    Increased flexibility for Aiven for PostgreSQL® advanced parameters

    You can now decrease several key advanced parameters for Aiven for PostgreSQL® that were previously restricted to increase only. This allows for better resource allocation and fine-tuning of your database instances as your workloads change.

    The following parameters can now be adjusted both up and down:

    • max_connections
    • max_locks_per_transaction
    • max_prepared_transactions
    • max_wal_senders
    • max_worker_processes

    Decreasing these parameters typically requires a service restart to apply the changes. Ensure you have a maintenance window or high-availability (HA) enabled before proceeding.

    Inkless service now available on Aiven Cloud

    The Inkless service is now available on Aiven Cloud. Inkless is Aiven’s open-source Apache Kafka® fork that introduces diskless topics and improves how Kafka services store and manage data compared to classic deployments.

    What’s new

    • Improves cluster scaling, rebalancing, and recovery compared to classic Kafka with tiered storage.
    • Supports both classic and diskless topics within the same Kafka service.
    • Stores retained data in object storage, reducing the need to pre-provision local disk for long-term retention.
    • Uses Apache Kafka 4.0.

    Limitations

    • Available only for new services; Classic Kafka services cannot be upgraded to Inkless at this time.

    For more information, see the Inkless overview documentation.

    • Aiven Terraform provider

    Aiven Provider for Terraform version 4.51.0 now available

    This release improves PrivateLink management with enhanced GCP PrivateLink connection approval through the new psc_connection_id field in aiven_gcp_privatelink_connection_approval. It lets you select specific connections when multiple PSC connections exist for the same service. Additionally, privatelink_connection_id support has been added across all service resources and data sources.

    Other key improvements in this release include:

    • Enhanced Valkey user management: ACL fields (valkey_acl_categories, valkey_acl_commands, valkey_acl_keys, valkey_acl_channels) can now be updated in-place without forcing resource recreation
    • Improved Kafka topic handling: Better support for infinite retention with retention_bytes = -1
    • OpenSearch 3.3 support: The latest OpenSearch version is now available

    This release also includes various bug fixes for MySQL user password updates, service cloud name handling, and billing group configurations. For complete details on all fixes and updates, view the full Aiven Provider for Terraform changelog.

    IPv6 client connectivity for Aiven for Apache Kafka® (Early availability)

    Aiven for Apache Kafka® now supports dual-stack IPv4 and IPv6 connectivity. When enabled, Kafka clients can connect using either IPv4 or IPv6 addresses. The feature is disabled by default and can be enabled by setting the service user configuration enable_ipv6 to true.
    This change may affect existing clients that connect over private network routes. Validate the behavior in a non-production environment before enabling it in production.

    For more information, see Enable IPv6 connectivity for Aiven for Apache Kafka®.

    Google external account credential restrictions for Apache Kafka Connect

    Aiven for Apache Kafka Connect validates Google Cloud external account credentials to block unsupported credential sources and requires allow-listing authentication URLs using gcp_auth_allowed_urls. File- and command-based credential sources are not supported.

    Impact:

    If a connector uses credential_source.url, configure gcp_auth_allowed_urls at the Kafka Connect service level. Connectors using file- or command-based credential sources fail validation.
