      Aiven for OpenSearch®

    Upgrade to OpenSearch® 3.8

    OpenSearch® version 3.8 is now available for Aiven for OpenSearch® services. Apply this version on your services to benefit from the 3.8 improvements.

    Highlights

    • Faster vector ingestion: Base64-encoded vector ingestion for knn_vector fields cuts network payload by 74%, delivering up to 4.16x higher bulk ingestion throughput and 83% lower median latency. A benefit for anyone running large-scale semantic search or RAG pipelines.
    • Broader MCP support for AI agents: Model Context Protocol (MCP) support now extends to flow and conversational flow agents, so all four agent architectures can connect to external MCP-compliant tool servers through a consistent connector configuration.
    • Better log analytics with PPL: A new visual PPL query builder lets you construct queries from menus instead of writing raw PPL, four new PPL commands (makeresults, foreach, xyseries, and timewrap) enable period-over-period comparisons, and a new lint engine flags mistakes as you type.
    • Faster troubleshooting in Dashboards: A new Grok Debugger in Dev Tools lets you validate Grok patterns against a sample log line, and a new "Create alert rule" action lets you go from spotting a metric pattern to alerting on it without leaving the page.
    • Security fix: The release upgrades dependencies to address CVE vulnerabilities.

      Aiven Runtime

    Control access to Aiven Runtime applications with OIDC

    You can now add OpenID Connect (OIDC)-compliant identity providers like Auth0, Microsoft Entra ID, and Okta, to restrict access to your Runtime applications.

    By default, applications are publicly accessible to anyone with the URL. Adding an identity provider to an application lets you secure your application by controlling which users and groups can access it. You can add multiple identity providers to an application.

    More information and setup instructions are available in the Aiven documentation.

    Aiven for OpenSearch® cross-cluster search now in limited availability

    Cross-cluster search for Aiven for OpenSearch® is now in limited availability. Connect your Aiven for OpenSearch service to another OpenSearch cluster and query indices on both clusters in a single search request.

    You can now:

    • Manage remote clusters in the Aiven Console, from the Cross-cluster search section on your service's overview page. Add a remote cluster to search, or allow another cluster to search yours.
    • Set a custom cluster alias to use in the <alias>:index query syntax, instead of relying on the automatically derived name.

    Both services must run the same OpenSearch major version and have matching security management settings. Contact Aiven to enable cross-cluster search for your project.

    For more information, see Set up cross-cluster search for Aiven for OpenSearch®.

      Aiven for PostgreSQL®

    Data API for Aiven for PostgreSQL®

    Aiven for PostgreSQL® now supports Data API, a new way to turn your database into a backend. It exposes your tables as secure REST endpoints directly from the Aiven Console, without backend code to write or host.

    Data API is powered by PostgREST and appears under Connect > Data API in the service menu. Key capabilities:

    • Instant REST endpoints: generated from your database schema, with GET, POST, PATCH, and DELETE methods per table.
    • Authentication with your identity provider: authenticate requests with JWTs issued by your own identity provider (Auth0, Okta, Microsoft Entra ID).
    • Authorization with PostgreSQL roles: standard roles and table privileges control access, based on the role carried in the token.
    • Dedicated, separately billed application: Data API runs as its own Aiven Runtime application. Use the recommended cloud, region, and plan, or configure your own.

    Data API is an early availability feature available for select plans and clouds.

    For more information, see Data API for Aiven for PostgreSQL.

    Karapace 6.2.4 now available with IMPORT mode for schema migration

    Karapace 6.2.4 is now available as a maintenance update for Aiven for Apache Kafka®.

    New feature

    • Schema migration with IMPORT mode: Migrate schemas from another schema registry and keep their original schema IDs and version numbers. You can set IMPORT mode for the entire registry or for a single subject. To export and import schemas between registries, use the sr_migrate.py migration script. For migration steps, see Migrate schemas with IMPORT mode.

    Improvements and fixes

    • OIDC authentication: The iss and aud claims are now optional when you configure OpenID Connect (OIDC) authentication for Schema Registry.
    • GET /schemas response: By default, the endpoint now returns only current schemas. To include soft-deleted schemas, set deleted=true. Previously, the endpoint returned soft-deleted schemas by default.

    For the full list of changes, see the Karapace 6.2.4 release notes.
