# ClickHouse

You can use the ClickHouse connector from the CData Sync application to move data
from any supported source to the ClickHouse destination. To do so, you need to add
the connector, authenticate to the connector, and complete your connection.

## Add the ClickHouse Connector

To enable Sync to use data from ClickHouse, you first must add the
connector, as follows:

<ol>
  <li>Open the **Connections** page of the Sync dashboard.</li>
  <li>Click **Add Connection** to open the **Select Connectors** page.</li>
  <li>Click the **Destinations** tab and locate
  the **ClickHouse** row.</li>

  <li>
    Click the **Configure Connection** icon at the end of that row to open
    the **New Connection** page. This action opens the
    **Add Connection** dialog.

    **Note:** If the **Configure Connection** icon is not
    available, click the **Download Connector** icon to install
    the ClickHouse connector.
  </li>

  <li>Enter a name for your connection in the **Add Connection** dialog.</li>
  <li>Click **Add** to open the **Settings** tab for your connector.</li>
</ol>

For more information about installing new connectors, see
[Connections](https://docs.sync.cdata.com/26.4/en/connections/connections.md).

## Authenticate to ClickHouse

After you add the connector, you need to set the required properties.

* **Protocol:** Select a protocol from the drop-down list (**HTTP** or **TLS/SSL** ). **HTTP** is the default value.
* **Endpoint:** Enter the URL of the endpoint that you want to use.
* **Port:** Enter the port number for the ClickHouse server. The default port value is **8123**.
* **Database:** Enter the name of your ClickHouse database.
* **User:** Enter the username that you use to authenticate to ClickHouse.
* **Password:** Enter the password that you use to authenticate to ClickHouse.

## Complete Your Connection

To complete your connection:

1. Define advanced connection settings on the **Advanced** tab. (In most cases, though, you should not need these settings.)
2. Click **Create & Test** to create your connection.
