Integrating Amazon Kinesis with ClickHouse Cloud


You have familiarized yourself with the ClickPipes intro and setup IAM credentials or an IAM Role. Follow the Kinesis Role-Based Access guide for information on how to setup a role that works with ClickHouse Cloud.

Creating your first ClickPipe

  1. Access the SQL Console for your ClickHouse Cloud Service.

    ClickPipes service

  2. Select the Data Sources button on the left-side menu and click on "Set up a ClickPipe"

    Select imports

  3. Select your data source.

    Select data source type

  4. Fill out the form by providing your ClickPipe with a name, a description (optional), your IAM role or credentials, and other connection details.

    Fill out connection details

  5. Select Kinesis Stream and starting offset. The UI will display a sample document from the selected source (Kafka topic, etc).

    Set data format and topic

  6. In the next step, you can select whether you want to ingest data into a new ClickHouse table or reuse an existing one. Follow the instructions in the screen to modify your table name, schema, and settings. You can see a real-time preview of your changes in the sample table at the top.

    Set table, schema, and settings

    You can also customize the advanced settings using the controls provided

    Set advanced controls

  7. Alternatively, you can decide to ingest your data in an existing ClickHouse table. In that case, the UI will allow you to map fields from the source to the ClickHouse fields in the selected destination table.

    Use and existing table

  8. Finally, you can configure permissions for the internal clickpipes user.

Permissions: ClickPipes will create a dedicated user for writing data into a destination table. You can select a role for this internal user using a custom role or one of the predefined role:

- `Full access`: with the full access to the cluster. It might be useful if you use Materialized View or Dictionary with the destination table.
- `Only destination table`: with the `INSERT` permissions to the destination table only.


  1. By clicking on "Complete Setup", the system will register you ClickPipe, and you'll be able to see it listed in the summary table.

    Success notice

    Remove notice

    The summary table provides controls to display sample data from the source or the destination table in ClickHouse

    View destination

    As well as controls to remove the ClickPipe and display a summary of the ingest job.

  2. Congratulations! you have successfully set up your first ClickPipe. If this is a streaming ClickPipe it will be continuously running, ingesting data in real-time from your remote data source. Otherwise it will ingest the batch and complete.
