### BYOC (beta)[​](#byoc-beta "Direct link to BYOC (beta)")

Bring Your Own Cloud for AWS is now available in Beta. This deployment model allows you to deploy and run ClickHouse Cloud in your own AWS account. We support deployments in 11+ AWS regions, with more coming soon. Please [contact support](https://clickhouse.com/support/program) for access. Note that this deployment is reserved for large-scale deployments.

### Postgres Change Data Capture (CDC) connector in ClickPipes[​](#postgres-change-data-capture-cdc-connector-in-clickpipes "Direct link to Postgres Change Data Capture (CDC) connector in ClickPipes")

This turnkey integration enables customers to replicate their Postgres databases to ClickHouse Cloud in just a few clicks and leverage ClickHouse for blazing-fast analytics. You can use this connector for both continuous replication and one-time migrations from Postgres.

### Dashboards (beta)[​](#dashboards-beta "Direct link to Dashboards (beta)")

This week, we're excited to announce the Beta launch of Dashboards in ClickHouse Cloud. With Dashboards, you can turn saved queries into visualizations, organize visualizations onto dashboards, and interact with dashboards using query parameters. To get started, follow the [dashboards documentation](/docs/cloud/manage/dashboards).

### Query API endpoints (GA)[​](#query-api-endpoints-ga "Direct link to Query API endpoints (GA)")

We are excited to announce the GA release of Query API Endpoints in ClickHouse Cloud. Query API Endpoints allow you to spin up RESTful API endpoints for saved queries in just a couple of clicks and begin consuming data in your application without wrangling language clients or authentication complexity. Since the initial launch, we have shipped a number of improvements, including:

- Reducing endpoint latency, especially for cold-starts
- Increased endpoint RBAC controls
- Configurable CORS-allowed domains
- Result streaming
- Support for all ClickHouse-compatible output formats

In addition to these improvements, we are excited to announce generic query API endpoints that, leveraging our existing framework, allow you to execute arbitrary SQL queries against your ClickHouse Cloud services. Generic endpoints can be enabled and configured from the service settings page.

To get started, follow the [Query API Endpoints documentation](/docs/cloud/get-started/query-endpoints).

### Native JSON support (Beta)[​](#native-json-support-beta "Direct link to Native JSON support (Beta)")

We are launching Beta for our native JSON support in ClickHouse Cloud. To get started, please get in touch with support [to enable your cloud service](/docs/cloud/support).

### Vector search using vector similarity indexes (early access)[​](#vector-search-using-vector-similarity-indexes-early-access "Direct link to Vector search using vector similarity indexes (early access)")

We are announcing vector similarity indexes for approximate vector search in early access.

ClickHouse already offers robust support for vector-based use cases, with a wide range of [distance functions]<https://clickhouse.com/blog/reinvent-2024-product-announcements#vector-search-using-vector-similarity-indexes-early-access>) and the ability to perform linear scans. In addition, more recently, we added an experimental [approximate vector search](/docs/engines/table-engines/mergetree-family/annindexes) approach powered by the [usearch](https://github.com/unum-cloud/usearch) library and the Hierarchical Navigable Small Worlds (HNSW) approximate nearest neighbor search algorithm.

To get started, [please sign up for the early access waitlist](https://clickhouse.com/cloud/vector-search-index-waitlist).

To get started and set up a resource share, you can read the [announcement post](https://clickhouse.com/blog/clickpipes-crossvpc-resource-endpoints?utm_medium=web&utm_source=changelog).

### Built-in advanced observability dashboard for ClickHouse Cloud[​](#built-in-advanced-observability-dashboard-for-clickhouse-cloud "Direct link to Built-in advanced observability dashboard for ClickHouse Cloud")

Previously, the advanced observability dashboard that allows you to monitor ClickHouse server metrics and hardware resource utilization was only available in open-source ClickHouse. We are happy to announce that this feature is now available in the ClickHouse Cloud console.

This dashboard allows you to view queries based on the [system.dashboards](/docs/operations/system-tables/dashboards) table in an all-in-one UI. Visit **Monitoring > Service Health** page to start using the advanced observability dashboard today.

### AI-powered SQL autocomplete[​](#ai-powered-sql-autocomplete "Direct link to AI-powered SQL autocomplete")

We've improved autocomplete significantly, allowing you to get in-line SQL completions as you write your queries with the new AI Copilot. This feature can be enabled by toggling the **"Enable Inline Code Completion"** setting for any ClickHouse Cloud service.

### New "billing" role[​](#new-billing-role "Direct link to New \"billing\" role")

### Customer Notifications in ClickHouse Cloud[​](#customer-notifications-in-clickhouse-cloud "Direct link to Customer Notifications in ClickHouse Cloud")

ClickHouse Cloud now provides in-console and email notifications for several billing and scaling events.

You can configure the category and severity of the notifications you receive at the service level.

In future, we will add notifications for other events, as well as additional ways to receive the notifications.

Please see the [ClickHouse docs](/docs/cloud/notifications) to learn more about how to enable notifications for your service.
