Sample dataset #
The sample dataset provides data in two tables that represent space mission
data. The following tables are available in the
demo schema of the catalog:
Configure a catalog #
To create a catalog with the sample dataset, select Catalogs in the main navigation and click Configure a catalog. Click on the Sample dataset button in the Select a dataset section.
Select a cloud provider #
The Cloud provider configuration is necessary to allow Starburst Galaxy to correctly match catalogs and clusters.
The data source configured in a catalog, and the cluster must operate in the same cloud provider and region for performance and cost reasons.
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.
The Region of the dataset catalog determines in which cloud region of a specific cloud provider the data is stored. Choose the same region as the cluster in which you want to use the dataset from the drop down.
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.
