     Username, Password	The username and password for authentication. Make sure the user has the required database permissions.
     Catalog (optional)	Select a catalog from all available catalogs in the cluster. If left empty, the internal default catalog is used.
     FE Node URL	The FE node endpoint for web server access, in the format {FE IP}:{HTTP Port}. The default HTTP port is 8030. Separate multiple FE node endpoints with commas (,).

5. Click Test Connection. After the test succeeds, click Save.

Manage SelectDB or Doris clusters

1. In the top menu bar of the Dataphin homepage, choose Planning > Compute Source.

2. On the Compute Source page, click Manage SelectDB Clusters or Manage Doris Clusters.

3. In the Manage SelectDB Clusters or Manage Doris Clusters dialog box, view the cluster list. The list displays the cluster name, cluster administrator, associated compute sources, creation information, and modification information.

   • Associated Compute Sources: The total number of associated compute sources. Click the icon to view the list. Click a compute source name to go to the compute source page.

   • Creation Information: The creator and creation time.

   • Modification Information: The user who last edited the cluster and the modification time.

   Note

   Compute tasks can run only in one cluster. Data from different SelectDB or Doris clusters cannot be joined.

4. (Optional) Enter a cluster name in the search box to perform a fuzzy search.

5. In the Actions column, you can perform the following operations on a cluster.

   Operation	Description
   View	Click the icon in the Actions column of the target cluster to view the details of the cluster's current version.
   Edit	Click the icon in the Actions column of the target cluster to open the edit page. Modify the configurations as needed, and then click Save. In the dialog box that appears, enter a Change Description and click OK.
   Clone	Click the icon in the Actions column of the target cluster to clone all data from the cluster and open the Create SelectDB or Doris cluster page, where you can modify the configuration.
   Historical versions	Click the icon in the Actions column of the target cluster, and select History. A dialog box appears and displays information about each version of the current cluster, including the version name, modifier, and change description. You can perform View and Compare operations on the historical versions. View: Click the icon in the Actions column of the target version to open the View SelectDB or Doris Cluster page and view the detailed information of the current version of the cluster. Compare: Click the icon in the Actions column of the target version to open the version comparison page. On the comparison page, you can select a different version from the filter drop-down list. By default, the current version of the SelectDB or Doris cluster is compared with the target version.
   Delete	Note You can delete the current cluster only when there are no associated compute sources under the current SelectDB or Doris cluster. Deleted clusters cannot be recovered. Click the icon in the Actions column of the target cluster, select Delete, and in the dialog box that appears, click OK.
