  • Smarter auto-scaling with two-window recommender: ClickHouse Cloud now uses a dual-lookback-window approach to vertical auto-scaling, replacing the previous single 30-hour window with a combined 3-hour "small window" and 30-hour "large window." This reduces scale-down latency from up to 30 hours to as little as 3 hours, lowering infrastructure costs for variable workloads without sacrificing scale-up responsiveness. Read the blog post for more details.
  • Monitoring in the Cloud console: New overview and infrastructure dashboards provide better visibility into the behavior of ClickHouse servers. Admin users now receive email notifications for common issues when using ClickHouse Cloud. Read the blog post for more details.
  • Compute-compute separation (warehouses): Support for auto-idling on primary services (also referred to as parent services) is now rolling to public preview. If the feature has not been enabled for your organization, contact support for access. Once the feature moves to general access, the default behavior will be that existing primary services will have the option to turn on auto-idling and new primary services will have it enabled by default.
  • Data Catalog integration: ClickHouse Cloud now supports Iceberg REST Catalog and Microsoft OneLake as data lake catalog integrations in the data sources UI. Once connected, the catalog appears as a database, allowing you to read Iceberg tables directly, without duplicating data.
  • Bring Your Own Cloud (BYOC) on GCP is now generally available: ClickHouse BYOC is now GA on Google Cloud, allowing you to deploy ClickHouse services in your own GCP project, and comply with strict data residency requirements. Read the documentation and the blog post for more details. You can contact us to request access.
  • Billing notifications for prepaid credits and payment method changes: ClickHouse Cloud now sends notifications when prepaid credits are added to your organization following a committed contract, or when a payment method is updated (credit card or marketplace subscription). Notifications are enabled by default for UI and email, and can be configured to also send to Slack.

  • Custom date range for Usage Breakdown: You can now view your usage costs across all billing dimensions on the usage breakdown screen using a custom date range. Select a start and end date (inclusive) to filter costs by a specific period and download the results as a CSV. The date range is limited to a maximum of 31 days.

February 20, 2026​

  • ClickPipes: Reverse private endpoints in an inactive state will now be automatically removed after a defined grace period. This ensures unused or misconfigured endpoints are not persisted indefinitely in the backend. See the automatic clean up documentation for more details.

    • GCP europe-west4 (Netherlands)

  • ClickPipes is now available in AWS eu-west-1. For new ClickHouse Cloud services created from January 20 in that region, the matching region will be used for ClickPipes. For older services, ClickPipes defaults to eu-central-1. See the documentation for more details.

  • Service-level usage cost filtering via API: Our API now supports filtering your organization's usage costs by specific service tags, making it easier to analyze spend at a more granular level.
  • Data Catalog integration: You can now connect an external data catalog as a data source. ClickHouse Cloud supports AWS Glue and Unity Catalog (with more coming soon). Once connected, the catalog appears as a database, allowing you to read Iceberg tables directly—without duplicating data. For access, contact support to request access.
  • ClickPipes:
    • The MongoDB connector has been promoted to Public Beta, and is now available to new and existing ClickHouse Cloud customers, in all service tiers. Read the blogpost for an overview of new features and head to the documentation to get started.
    • The S3 ClickPipe is now compatible with OVH Object Storage, the S3 API-compatible object storage service in OVHcloud.
