MongoDB catalogs #
Configure a catalog #
To create a MongoDB catalog, select Catalogs in the main navigation and click Configure a catalog. On the Select a data source screen, click MongoDB.
Define catalog name and description #
The Name of the catalog is visible in the Query editor and other clients. It is used to identify the catalog when writing SQL or showing the catalog and its nested schemas and tables in client applications.
The name is displayed in the Query editor, and when running a SHOW
CATALOGS command. It is used to fully
qualify the name of any table in SQL queries following the
catalogname.schemaname.tablename syntax. For example, you can run the
following query in the sample cluster without first setting the catalog or
SELECT * FROM tpch.sf1.nation;
The Description is a short, optional paragraph that provides further details about the catalog. It appears in the Starburst Galaxy user interface and can help other users determine what data can be accessed with the catalog.
MongoDB configuration #
To configure the connection to your MongoDB or Atlas data platform, you must
provide a URI to your account in the form:
Test the connection #
Once you have configured the connection details, use the Test connection button to confirm data access is working. If the test is successful, you can save the catalog.
If the test fails, Starburst Galaxy provides detailed diagnostic information that you can use to fix the database configuration in the cloud provider system.
Connect catalog #
Click Connect catalog, and proceed to set permissions where you can grant access to certain roles.
Set permissions #
This optional step allows you to configure read only access to the catalog.
Click Skip to go straight to adding the catalog to a cluster. If you skip this step, you can add read only access to your catalog for any Starburst Galaxy role later. Skipping this step leaves only the following roles with access to schemas and tables in the catalog:
- administrative roles
- the currently logged-in role that created the catalog
Setting permissions grants all specified roles read only access to the catalog. As a result, users have read access to all contained schema, tables, and views.
Use the following steps to assign read access to roles:
- In the Read access to this catalog section, expand the drop-down in the Roles with read access field.
- Select one or more Starburst Galaxy roles from the list to grant read access to the data.
Click Save access controls.
Add to cluster #
You can add your catalog to a cluster later by editing a cluster. Click Skip to proceed to the catalogs page.
Use the following steps to add your catalog to an existing cluster or create a new cluster in the same cloud region:
- In the Add to cluster section, expand the menu in the Select cluster field.
- Select one or more existing clusters from the drop down menu.
- Click Create a new cluster to create a new cluster in the same region, and add it to the cluster selection menu.
Click Add to cluster to view your new catalog’s configuration.
The Pending changes to clusters dialog appears when you try to add a catalog to a running cluster.
- In the Pending changes to cluster dialog, click Return to catalogs to edit the catalog or create a new catalog.
- Click Go to clusters to confirm the addition of the catalog to the running cluster.
On the Clusters page, click the Update icon beside the running cluster, to add the catalog.
