ClickHouse Cloud now lets you export backups directly to your own cloud service provider account.
Connect your external storage bucket - AWS S3, Google Cloud Storage, or Azure Blob Storage - and take control of your backup management.
August 29, 2025
* [ClickHouse Cloud Azure Private Link](/products/cloud/guides/security/connectivity/private-networking/azure-privatelink) has switched from using Resource GUID to Resource ID filters for resource identification. You can still use the legacy Resource GUID, which is backward compatible, but we recommend switching to Resource ID filters. For migration details see the [docs](/products/cloud/guides/security/connectivity/private-networking/azure-privatelink#obtaining-private-endpoint-resourceid) for Azure Private Link.
August 22, 2025
* **ClickHouse Connector for AWS Glue**\
You can now use the official [ClickHouse Connector for AWS Glue](/integrations/connectors/data-ingestion/AWS/glue) that is available from the [AWS Marketplace](https://aws.amazon.com/marketplace/pp/prodview-eqvmuopqzdg7s). Utilizes AWS Glue's Apache
Spark-based serverless engine for extracting, transforming and loading data integration between ClickHouse and other data sources. Get
started by following along with the announcement [blogpost](http://clickhouse.com/blog/clickhouse-connector-aws-glue) for how to create tables, write and read data between ClickHouse and Spark.
* **Change to the minimum number of replicas in a service**\
Services which have been scaled up can now be [scaled back down](/products/cloud/features/autoscaling/overview) to use a single replica (previously the minimum was 2 replicas). Note: single replica services have reduced availability and are not recommended for production usage.
* ClickHouse Cloud will begin to send notifications related to service scaling and service version upgrades, by default for administrator roles. You can adjust their notification preferences in their notification settings.
August 13, 2025

January 27, 2025
Changes to ClickHouse Cloud tiers
We are dedicated to adapting our products to meet the ever-changing requirements of our customers. Since its introduction in GA over the past two years, ClickHouse Cloud has evolved substantially, and we've gained invaluable insights into how our customers leverage our cloud offerings.
We are introducing new features to optimize the sizing and cost-efficiency of ClickHouse Cloud services for your workloads. These include **compute-compute separation**, high-performance machine types, and **single-replica services**. We are also evolving automatic scaling and managed upgrades to execute in a more seamless and reactive fashion.
We are adding a **new Enterprise tier** to serve the needs of the most demanding customers and workloads, with focus on industry-specific security and compliance features, even more controls over underlying hardware and upgrades, and advanced disaster recovery features.
To support these changes, we are restructuring our current **Development** and **Production** tiers to more closely match how our evolving customer base is using our offerings. We are introducing the **Basic** tier, oriented toward users that are testing out new ideas and projects, and the **Scale** tier, matching users working with production workloads and data at scale.
You can read about these and other functional changes in this [blog](https://clickhouse.com/blog/evolution-of-clickhouse-cloud-new-features-superior-performance-tailored-offerings). Existing customers will need to take action to select a [new plan](https://clickhouse.com/pricing). Customer-facing communication was sent via email to organization administrators.
Warehouses: Compute-compute separation (GA)
Compute-compute separation (also known as "Warehouses") is Generally Available; please refer to [blog](https://clickhouse.com/blog/introducing-warehouses-compute-compute-separation-in-clickhouse-cloud) for more details and the [documentation](/products/cloud/features/infrastructure/warehouses).
Single-replica services
We are introducing the concept of a "single-replica service", both as a standalone offering and within warehouses. As a standalone offering, single-replica services are size limited and intended to be used for small test workloads. Within warehouses, single-replica services can be deployed at larger sizes, and utilized for workloads not requiring high availability at scale, such as restartable ETL jobs.
Vertical auto-scaling improvements
We are introducing a new vertical scaling mechanism for compute replicas, which we call "Make Before Break" (MBB). This approach adds one or more replicas of the new size before removing the old replicas, preventing any loss of capacity during scaling operations. By eliminating the gap between removing existing replicas and adding new ones, MBB creates a more seamless and less disruptive scaling process. It is especially beneficial in scale-up scenarios, where high resource utilization triggers the need for additional capacity, since removing replicas prematurely would only exacerbate the resource constraints.
Horizontal scaling (GA)
Horizontal scaling is now Generally Available. You can add additional replicas to scale out their service through the APIs and the cloud console. Please refer to the [documentation](/products/cloud/features/autoscaling/horizontal#manual-horizontal-scaling) for information.
Configurable backups
We now support the ability for customers to export backups to their own cloud account; please refer to the [documentation](/products/cloud/guides/backups/configurable-backups) for additional information.
Managed upgrade improvements
Safe managed upgrades deliver significant value to our users by allowing them to stay current with the database as it moves forward to add features. With this rollout, we applied the "make before break" (or MBB) approach to upgrades, further reducing impact to running workloads.
HIPAA support
We now support HIPAA in compliant regions, including AWS `us-east-1`, `us-west-2` and GCP `us-central1`, `us-east1`. Customers wishing to onboard must sign a Business Associate Agreement (BAA) and deploy to the compliant version of the region. For more information on HIPAA, please refer to the [documentation](/products/cloud/reference/security/compliance-overview).
Scheduled upgrades
You can schedule upgrades for your services. This feature is supported for Enterprise tier services only. For more information on Scheduled upgrades, please refer to the [documentation](/products/cloud/features/admin-features/upgrades).
Language client support for complex types
[Golang](https://github.com/ClickHouse/clickhouse-go/releases/tag/v2.30.1), [Python](https://github.com/ClickHouse/clickhouse-connect/releases/tag/v0.8.11), and [NodeJS](https://github.com/ClickHouse/clickhouse-js/releases/tag/1.10.1) clients added support for Dynamic, Variant, and JSON types.
DBT support for refreshable materialized views
DBT now [supports Refreshable Materialized Views](https://github.com/ClickHouse/dbt-clickhouse/releases/tag/v1.8.7) in the `1.8.7` release.
JWT token support
Support has been added for JWT-based authentication in the JDBC driver v2, clickhouse-java, [Python](https://github.com/ClickHouse/clickhouse-connect/releases/tag/v0.8.12), and[ NodeJS](https://github.com/ClickHouse/clickhouse-js/releases/tag/1.10.0) clients.
JDBC / Java will be in[ 0.8.0](https://github.com/ClickHouse/clickhouse-java/releases/tag/v0.8.0) when it's released - ETA pending.
Prometheus integration improvements
We've added several enhancements for the Prometheus integration:
* **Organization-level endpoint**. We've introduced an enhancement to our Prometheus integration for ClickHouse Cloud. In addition to service-level metrics, the API now includes an endpoint for **organization-level metrics**. This new endpoint automatically collects metrics for all services within your organization, streamlining the process of exporting metrics into your Prometheus collector. These metrics can be integrated with visualization tools like Grafana and Datadog for a more comprehensive view of your organization's performance.
This feature is available now for all users. You can find more details [here](/products/cloud/features/monitoring/prometheus).
* **Filtered metrics**. We've added support for returning a filtered list of metrics in our Prometheus integration for ClickHouse Cloud. This feature helps reduce response payload size by enabling you to focus on metrics that are critical for monitoring the health of your service.
This functionality is available via an optional query parameter in the API, making it easier to optimize your data collection and streamline integrations with tools like Grafana and Datadog.
The filtered metrics feature is now available for all users. You can find more details [here](/products/cloud/features/monitoring/prometheus).
