May 28, 2026

ClickStack Cloud private preview

ClickStack Cloud is a fully managed, serverless observability platform built on ClickHouse Cloud. Teams can send OpenTelemetry data to a managed endpoint and immediately explore logs, metrics, and traces without operating observability infrastructure. Available in private preview on AWS us-east-1. Read the blog post for more details and join the waitlist for access.

AI Notebooks for Managed ClickStack (beta)

AI Notebooks are now available in beta for Managed ClickStack, providing SREs and engineering teams with persistent, transparent workspaces for AI-assisted incident investigation. Notebooks support structured sequences of prompts, queries, charts, reasoning steps, and findings with branching workflows for exploring multiple hypotheses. See the documentation for more details.

ClickStack MCP Server

The new open-source ClickStack MCP Server gives external AI agents structured observability investigation tools built on ClickStack and ClickHouse. It exposes semantic investigation primitives for logs, metrics, and traces as well as bi-directional orchestration primitives for creating dashboards, persisting searches, and alerts. See the documentation and the blog post for more details.

May 27, 2026

Executable UDFs (public beta)

Executable UDFs are now in public beta on ClickHouse Cloud. You can write a function in Python, upload it to your cluster, and call it from SQL like any built-in function. ClickHouse runs a pool of long-lived sandboxed processes and pipes rows through them at query speed, so you can use your function anywhere SQL works — ad-hoc queries, joins, and even materialized views that fire on every insert. Read the announcement blog for more details.

ClickPipes runs natively on GCP

ClickPipes infrastructure now runs natively on GCP for all new ClickHouse Cloud services hosted on GCP (created after May 26), including support for Private Service Connect (PSC). This eliminates cross-cloud egress costs, enables GCP-native private networking, reduces latency, and provides data locality guarantees. See the list of supported GCP regions.

ClickPipes for GCP Pub/Sub (private preview)

ClickPipes now supports streaming data from GCP Pub/Sub topics directly into ClickHouse Cloud. Available in private preview — sign up for access. See the documentation for more details.

ClickHouse Agents — agentic analytics (public beta)

ClickHouse Agents is now in public beta — a first-party agentic analytics surface powered by Claude that lets users build, run, and orchestrate agents against their ClickHouse data. Features include schema-aware conversational analysis, AgentBuilder with MCP support, subagent topologies, and code generation. Available at ai.clickhouse.cloud.

ClickHouse Postgres (public beta)

Fully managed Postgres on local NVMe storage is now in public beta, delivering 5x+ more TPS than AWS RDS. A native CDC pipeline streams data directly into ClickHouse with no intermediate infrastructure. The open-source pg_clickhouse extension lets developers query ClickHouse tables from standard Postgres sessions. Read the blog post for more details.

May 26, 2026

Horizontal autoscaling (private preview)

Horizontal autoscaling automatically adjusts the number of replicas in a ClickHouse Cloud cluster based on the number of concurrent queries, scaling out when demand spikes and scaling in when load drops. Available in private preview for Enterprise and Scale tier customers on ClickHouse 26.2+. Contact support with your organization ID to enable.

May 25, 2026

GA release of organization spend alerts

Organization spend alerts are now generally available. Get notified at 50%, 75%, and 100% of your configured organization spend per billing period. Choose from Email, Cloud console (UI), and/or Slack as notification channels. Alerts are based on organization gross usage, fire hourly, and reset automatically each billing period. Requires Org Admin or Billing Admin role.

New ClickPipes AWS regions

The mx-central-1 (Mexico Central) AWS region is now live for ClickPipes, following the Cloud region launch. For ClickHouse Cloud services created in this region from May 19 2026, ClickPipes will be co-located in the same region. For services created prior to that date, ClickPipes will default to the us-east-2 region; if that’s the case, please reach out to our team to get your service patched to use the new region.

Primary service idling for compute-compute separation now generally available

Primary service idling for compute-compute separation is now generally available. All primary services now have the ability to idle.

May 8, 2026

Postgres query insights (private preview)

A new Query insights tab is now available in ClickHouse Cloud Managed Postgres (Private Preview). It ranks every query pattern by impact and shows why each one is slow across three surfaces:

• Overview — one-screen database health
• Patterns — table sortable by runtime, CPU, errors, and P95
• Per-pattern flyout — latency percentiles, CPU vs I/O, cache vs disk, temp spills, parallel-worker shortfalls, and WAL volume

Powered by pg_stat_ch, an open-source Postgres extension.

Data catalog integration expansions

We have expanded our support of data catalog integrations via the Data Sources UI with more auth methods, table formats, and data catalog flavors:

• IAM support for AWS Glue Catalog
• BigLake Metastore support for data catalog integration
• Delta Tables support on Unity Catalog

May 2, 2026

New GCP London region (europe-west2)

ClickHouse Cloud now supports a new public region: GCP London (europe-west2). See the full list of supported regions for more details.

April 25, 2026

Index sharding (private preview)

Index sharding is now available in private preview. This feature distributes the index analysis phase across multiple replicas, reducing per-replica memory usage and improving query performance through distributed parallelization. This is especially beneficial for tables with heavy secondary indexes such as vector search and full-text search. Read the blog post for more details.

Terraform & OpenAPI for ClickPipes (general access)

ClickPipes resources in the ClickHouse Terraform provider are now generally available as part of stable releases, and OpenAPI endpoints are no longer marked as beta. This includes full coverage for CDC connectors (Postgres, MySQL, MongoDB). See the Terraform documentation, OpenAPI documentation, and blog post for more details.

April 17, 2026

Refunds visible in billing UI

Customers can now see all refunds directly in the Cloud console billing UI. Refunds appear once processed; credit card refunds may take additional time to show on statements depending on the bank.

Organization spend alerts (Private Preview)

Organization spend alerts are now available in Private Preview. Get notified at 50%, 75%, and 100% of your configured organization spend per billing period. Choose from Email, Cloud console, and/or Slack notification channels. Alerts are based on organization gross usage, fire hourly, and reset automatically each billing period. Requires Org Admin or Billing Admin role.

ClickPipes region parity on AWS

ClickPipes is now available in all AWS regions (public and private) supported by ClickHouse Cloud, expanding from 6 regions to 18. This includes strategic regions like Singapore (ap-southeast-1), Seoul (ap-northeast-2), and Tokyo (ap-northeast-1). The new regions are available for services created after April 14, 2026. See the documentation for more details.

April 10, 2026

Centralized marketplace billing

Customers can now consolidate billing across organizations through a single cloud marketplace subscription (AWS, Azure, and GCP). Key updates include:

• Marketplace Subscription Sharing: Switch an organization from credit card billing to an existing marketplace subscription from another organization, removing the need to set up an additional marketplace subscription. Only PAYG usage is consolidated (not prepaid credits).
• Update Marketplace Subscriptions: Swap an organization’s marketplace subscription to one used by a different organization.
• Backup Payment Method: Organizations on marketplace billing can now add a credit card as a fallback if the primary marketplace subscription is cancelled or expires.

See the billing documentation for more details.

clickhousectl CLI (public beta)

clickhousectl is the official ClickHouse CLI for managing local installations, running local servers, and operating ClickHouse Cloud. Install it now:

curl https://clickhouse.com/cli | sh

April 3, 2026

• 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.

March 20, 2026

• 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.

February 13, 2026

• BigQuery Connector is now in Private Preview. Read this blogpost for more details and join the waitlist for access.
• We are pleased to announce support for PCI deployments for Google Cloud. Regions supported:

  • GCP us-east1 (South Carolina)
• Crash report collection preferences can now be configured at the organization level. This setting was previously available only at the service level. When disabled at the organization level, all existing and future services will be opted out automatically.

January 23, 2026

• 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.

January 16, 2026

• 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.
