    Aiven Operator for Kubernetes

    Flink and autoscaler now supported in Aiven Operator for Kubernetes

    Aiven for Apache Flink® is supported in version 0.26.0. Support for the autoscaler service integration was also added with the ServiceIntegration field autoscaler and ServiceIntegrationEndpoint field autoscaler.

    Other additions in this release include:

    • The ClickHouse field userConfig.recovery_basebackup_name for the backup to restore in a forked service.
    • The Grafana field userConfig.auth_generic_oauth.use_refresh_token to refresh tokens and check access token expiration.
    • The Kafka field userConfig.schema_registry_config.retriable_errors_silenced to silence errors that can be retried or custom errors you specify.
    • The Kafka field userConfig.schema_registry_config.schema_reader_strict_mode to configure the Karapace schema-registry service to shutdown when there are invalid schema records in the _schemas topic.
    • The OpenSearch fields userConfig.azure_migration.indices, userConfig.gcs_migration.indices, and userConfig.s3_migration.indices to define a list of indices to restore from the snapshot. Multi-index syntax is supported.

    The following are deprecated:

    • PostgreSQL field userConfig.additional_backup_regions
    • Grafana field userConfig.alerting_enabled

    For a full list of the changes and deprecations, check out the Aiven Operator changelog.

    TimescaleDB extension 2.17.1 for Aiven for PostgreSQL® released

    TimescaleDB extension version 2.17.1 is now available for Aiven for PostgreSQL®. It introduces new features, performance improvements, and bug fixes on top of release 2.16.1. Upgrade to 2.17.1 at your earliest convenience to make sure you use the most robust and secure version available.

    Refer to TimescaleDB release notes for all the changes introduced in this release.

    Key new features

    • Full PostgreSQL 17 support for all existing features:
      TimescaleDB 2.17.1 is available for PostgreSQL 14, 15, 16, and 17.
    • Significant performance improvements for continuous aggregate policies:
      Continuous aggregate refresh is now using merge instead of deleting old materialized data and re-inserting. This update can decrease dramatically the amount of data that must be written on the continuous aggregate in the presence of a small number of changes, reduce the i/o cost of refreshing a continuous aggregate, and generate fewer Write-Ahead Logs (WAL). Overall, continuous aggregate policies will be more lightweight, use less system resources, and complete faster.
    • Increased performance for real-time analytical queries over compressed hypertables:
      Introducing additional Single Instruction, Multiple Data (SIMD) vectorization optimization to our engine by supporting vectorized execution for queries that group by using the segment_by column(s) and aggregate using the basic aggregate functions (sum, count, avg, min, max)
    • Improved performance of deletes on compressed hypertables when a large amount of data is affected:
      Speeding up operations that delete whole segments by skipping the decompression step (enabled for all deletes that filter by segment_by columns)

    PostgreSQL 14 deprecation announcement

    PostgreSQL 14 will be supported until April 2025. Closer to that time, there will be an announcement of the specific version of TimescaleDB in which PostgreSQL 14 support will not be included going forward.

    New features

    • #7360 Add chunk skipping GUC
    • #6882: Allow delete of full segments on compressed chunks without decompression.
    • #7033: Use merge statement on continuous aggregates refresh.
    • #7126: Add functions to show the compression information.
    • #7147: Vectorize partial aggregation for sum(int4) with grouping on segment by columns.
    • #7204: Track additional extensions in telemetry.
    • #7207: Refactor the decompress_batches_scan functions for easier maintenance.
    • #7209: Add a function to drop the osm chunk.
    • #7275: Add support for the returning clause for merge.
    • #7200: Vectorize common aggregate functions like min, max, sum, avg, stddev, variance for compressed columns of arithmetic types, when there is grouping on segment by columns or no grouping.

    • #7342 Fix collation for in-memory tuple filtering

    Aiven for Apache Kafka®

    Tiered storage in Aiven for Apache Kafka is now self-service

    You can now enable tiered storage in Aiven for Apache Kafka without needing to contact support.

    Key considerations:

    • Once enabled, tiered storage cannot be disabled.
    • Shutting down the service will result in permanent loss of data stored in tiered storage.
    • Tiered storage is available only on AWS, Google Cloud, and Microsoft Azure.

    For more information, see Get started with tiered storage and review the existing limitations for tiered storage.
