      Aiven for OpenSearch®

    Aiven for OpenSearch® Hobbyist plan retirement

    Aiven is retiring the Hobbyist plan for Aiven for OpenSearch®. From July 31, 2026, new customers cannot create Hobbyist services. Projects already running a Hobbyist service keep full access: existing services continue to run, and you can still create new Hobbyist services in those projects until further notice.

    We are making this change to improve the overall product experience. The current technical specifications of the Hobbyist plan don't provide the performance modern applications require, often leading to a sub-optimal experience.

    If you are starting a new Aiven for OpenSearch service, use the Developer tier. It gives you 4 GB RAM and 30 GB storage at $40/month for an always-on single node with daily backups. To change the plan for an existing Hobbyist service, upgrade the plan in the Aiven Console. See the Developer tier page for full specifications.

      Aiven Terraform provider

    Aiven Provider for Terraform version 4.61.0 now available

    This release adds support for new service configuration and integration options, while improving day-to-day Terraform stability.


    Highlights for this release:

    • Organization user groups are easier to manage. Group name and description can now be updated in place instead of forcing resource recreation.
    • PostgreSQL database reads are more reliable for services with larger database lists through pagination fixes.
    • OpenTelemetry integration is supported through new integration and endpoint types, including OpenTelemetry endpoint user configuration.
    • MySQL configuration coverage was expanded with many new optimizer and FULLTEXT settings.

    For more details on fixes and updates, view the complete Aiven Provider for Terraform changelog.

      Aiven for ClickHouse®

    Aiven for ClickHouse® 26.3 available in Early Availability

    Aiven for ClickHouse 26.3 LTS is available in Early Availability. You can use it for new services or upgrade an existing service from version 25.8.
    This release enables asynchronous inserts by default, makes full-text search generally available, introduces materialized common table expressions (CTEs), improves Map lookup performance, and includes upstream changes from versions 25.9 through 26.3.

    Before upgrading, Aiven checks the service for compatibility issues. Review the compatibility changes, removed features, and changed defaults, and test the upgrade on a service fork first.

    For details, see Upgrade to Aiven for ClickHouse 26.3 and the announcement blog.

      Aiven for OpenSearch®

    Hot/warm data tiering for Aiven for OpenSearch®

    Aiven for OpenSearch® now supports hot/warm data tiering on custom plans. This feature is in limited availability; contact Aiven to request access.

    Clusters with tiered storage run two groups of data nodes: hot nodes on fast storage for active data, and warm nodes on larger, lower-cost storage for older data that is queried less often. Index State Management (ISM) policies automate the full lifecycle: new indexes land on hot nodes, roll over when they reach a size or age threshold, migrate to warm nodes after a retention period, and are optionally deleted.

    Key details:

    • Requires Aiven for OpenSearch® 2.19 or later.
    • Configure index routing and ISM policies directly through the OpenSearch API or OpenSearch Dashboards.

    For setup instructions and ISM policy examples, see Hot/warm data tiering in Aiven for OpenSearch®.

      Aiven for Apache Kafka® Connect

    Preferred availability zones for Aiven for Apache Kafka® Connect and MirrorMaker 2

    Aiven now supports configuring preferred availability zones for Aiven for Apache Kafka® Connect and MirrorMaker 2 services. This extends the existing preferred zones feature from Kafka to these services, giving you control over where service nodes are placed within a cloud region.

    Use preferred zones to reduce cross-AZ data transfer costs, lower latency between service nodes and client applications, and meet workload placement requirements.

    To learn more, see Configure preferred availability zones.

      Aiven for Apache Kafka® Connect

    Azure Key Vault secret provider for Aiven for Apache Kafka® Connect

    Added support for the Azure Key Vault secret provider in Aiven for Apache Kafka® Connect. The Azure Key Vault provider reads secrets from Azure Key Vault and lets connector configurations reference them using ${PROVIDER_NAME:SECRET_KEY}.

    This keeps sensitive credentials, such as connection strings, API keys, and passwords, out of connector configuration files.

    You can configure the Azure Key Vault secret provider using the Aiven API, Aiven CLI, or Aiven Provider for Terraform.

    For more information, see Configure the Azure Key Vault secret provider.
