Tabular catalogs #
Use a Tabular catalog to configure access to a Tabular warehouse.
Follow these steps to begin creating a catalog for Tabular:
- In the navigation menu, select Catalogs.
- Click Create catalog.
On the Select a data source pane, click the Tabular icon.
- Follow the instructions in the next sections to configure your Tabular connection.
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.
Tabular configuration #
To configure the connection to your Tabular warehouse, provide the following details:
- Tabular URL: The default URL is entered for you. Do not change this URL except for testing under the guidance of a Support person.
- Tabular warehouse name: Provide the name of your Tabular warehouse.
- Tabular OAuth credential: Tabular uses an OAuth token instead of user name and password. Enter your OAuth token.
Test the connection #
Once you have configured the connection details, click Test connection to confirm data access is working. If the test is successful, you can save the catalog.
If the test fails, look over your entries in the configuration fields, correct any errors, and try again. If the test continues to fail, Galaxy provides diagnostic information that you can use to fix the data source 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 access, read only access, and full read and write access to the catalog.
Setting read only permissions grants the specified roles read only access to the catalog. As a result users have read only access to all contained schema, tables, and views.
Setting read/write permissions grants the specified roles full read and write access to the catalog. As a result users have full read and write access to all contained schema, tables, and views.
Use the following steps to assign read/write access to roles:
- In the Role-level permissions section, expand the menu in the Roles with read and write access field.
- From the list, select one or more roles to grant read and write access to.
- Expand the menu in the Roles with read access field.
- Select one or more roles from the list to grant read access to.
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.
