    Controlled maintenance updates for Aiven for PostgreSQL® (limited availability)

    Aiven for PostgreSQL® now supports controlled maintenance updates in limited availability. You can define user_config.switchover_windows so primary promotion during maintenance happens in your preferred low-traffic periods.

    Configured switchover windows apply to maintenance updates started automatically during the maintenance window and to manually started maintenance updates. This gives you more predictable maintenance timing and helps reduce operational impact.

    For more information, see Controlled maintenance updates in Aiven for PostgreSQL®.

    PG Studio: AI-powered SQL editor for Aiven for PostgreSQL® (early availability)

    PG Studio is a web-based, AI-enhanced data visualizer and querying tool built directly into the Aiven Console. It simplifies data interaction by combining a traditional workspace with an intelligent co-pilot, allowing you to move from natural language prompts to runnable SQL in seconds—without local setup or external clients.

    Key features

    This early availability release features the following:

    • Natural language to SQL: Generate precise SQL by describing your goal in plain English. The AI uses your unique schema map to ensure queries are context-aware and accurate.
    • Interactive schema mapping: Visualize your database structure through a dynamic map of tables, columns, and relationships, making it easy to navigate complex data models.
    • Query insights & explanations: Get instant breakdowns of existing queries, complex joins, or unfamiliar database objects to speed up troubleshooting and onboarding.
    • Zero configuration: Available instantly for all Aiven for PostgreSQL® services—optimized for fast debugging, data exploration, and ad-hoc analysis.

    Security and stability guardrails

    To protect your production environments, PG Studio includes built-in enterprise-grade safeguards:

    • Read-only by default: All queries execute in a read-only transaction, protecting your data from accidental modification (UPDATE, DELETE) or structural changes (DROP).
    • Privacy-first AI: Your data remains yours. We use only schema metadata for context; your actual database content is never used to train AI models.
    • Automatic safety limits: Includes single-statement validation and a 30-second query timeout to prevent runaway processes and maintain service stability.

    To get started, explore our public documentation and check out the Introducing Aiven’s PG Studio blog post.

    Upgrade Apache Kafka® services from ZooKeeper to KRaft

    Existing Aiven for Apache Kafka® services running Apache Kafka 3.8 can now migrate from ZooKeeper to KRaft when upgrading to Apache Kafka 3.9. The migration runs automatically as part of the standard service upgrade.

    Key considerations

    • Upgrading a service from Kafka 3.8 to Kafka 3.9 automatically migrates the service from ZooKeeper to KRaft.
    • The upgrade involves rolling restarts, which may cause temporary client reconnections.
    • ZooKeeper-related controller metrics are no longer available after migration.
    • Migration rollout includes temporary limitations such as supported service plans, migration windows, and limits on concurrent migrations.
    • Migrating to KRaft is required before upgrading to Apache Kafka 4.0 or later.

    For details, see KRaft in Aiven for Apache Kafka®.

    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.

    • 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.
