## July 11, 2025 {#june-11-2025}
35+
36+
- New services now store database and table metadata in a central **SharedCatalog**,
37+
a new model for coordination and object lifecycles which enables:
38+
- **Cloud-scale DDL**, even under high concurrency
39+
- **Resilient deletion and new DDL operations**
40+
- **Fast spin-up and wake-ups** as stateless nodes now launch with no disk dependencies
41+
- **Stateless compute across both native and open formats**, including Iceberg and Delta Lake
42+
43+
Read more about SharedCatalog in our [blog](https://clickhouse.com/blog/clickhouse-cloud-stateless-compute)
44+
45+
- We now support the ability to launch HIPAA compliant services in GCP `europe-west4`

- `multi_read` - support for read multi request. Default: `1`

- `filtered_list` - support for list request which filters results by the type of node (ephemeral or persistent). Default: `1`

- `check_not_exists` - support for `CheckNotExists` request, which asserts that node doesn't exists. Default: `0`
456-
- `create_if_not_exists` - support for `CreateIfNotExists` request, which will try to create a node if it doesn't exist. If it exists, no changes are applied and `ZOK` is returned. Default: `0`

## Prerequisites {#prerequisites}
28+
We assume you are familiar with:
29+
* [ClickHouse Connector Sink](../kafka-clickhouse-connect-sink.md)
30+
* Confluent Cloud
31+
32+
## The official Kafka connector from ClickHouse with Confluent Cloud {#the-official-kafka-connector-from-clickhouse-with-confluent-cloud}
33+
34+
### Installing on Confluent Cloud {#installing-on-confluent-cloud}
35+
This is meant to be a quick guide to get you started with the ClickHouse Sink Connector on Confluent Cloud.
36+
For more details, please refer to the [official Confluent documentation](https://docs.confluent.io/cloud/current/connectors/bring-your-connector/custom-connector-qs.html#uploading-and-launching-the-connector).
37+
38+
#### Create a Topic {#create-a-topic}
39+
Creating a topic on Confluent Cloud is fairly simple, and there are detailed instructions [here](https://docs.confluent.io/cloud/current/client-apps/topics/manage.html).
40+
41+
#### Important notes {#important-notes}
42+
43+
* The Kafka topic name must be the same as the ClickHouse table name. The way to tweak this is by using a transformer (for example [`ExtractTopic`](https://docs.confluent.io/platform/current/connect/transforms/extracttopic.html)).
44+
* More partitions does not always mean more performance - see our upcoming guide for more details and performance tips.
45+
46+
#### Gather your connection details {#gather-your-connection-details}
47+
<ConnectionDetails />
48+
49+
50+
#### Install Connector {#install-connector}
51+
Install the fully managed ClickHouse Sink Connector on Confluent Cloud following the [official documentation](https://docs.confluent.io/cloud/current/connectors/cc-clickhouse-sink-connector/cc-clickhouse-sink.html).
52+
53+
54+
#### Configure the Connector {#configure-the-connector}
55+
During the configuration of the ClickHouse Sink Connector, you will need to provide the following details:
56+
- hostname of your ClickHouse server
57+
- port of your ClickHouse server (default is 8443)
58+
- username and password for your ClickHouse server
59+
- database name in ClickHouse where the data will be written
60+
- topic name in Kafka that will be used to write data to ClickHouse
61+
62+
The Confluent Cloud UI supports advanced configuration options to adjust poll intervals, batch sizes, and other parameters to optimize performance.
63+
64+
#### Known limitations {#known-limitations}
65+
* See the list of [Connectors limitations in the official docs](https://docs.confluent.io/cloud/current/connectors/cc-clickhouse-sink-connector/cc-clickhouse-sink.html#limitations)
