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. Existing customers will need to take action to select a new plan. 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 for more details and the documentation.

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 for information.

Configurable backups​

We now support the ability for customers to export backups to their own cloud account; please refer to the documentation 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.

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.

Language client support for complex types​

Golang, Python, and NodeJS clients added support for Dynamic, Variant, and JSON types.

DBT support for refreshable materialized views​

DBT now supports Refreshable Materialized Views 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, and NodeJS clients.

JDBC / Java will be in 0.8.0 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.

  • 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.
