    Sample dataset #

    The sample dataset provides data in the following schemas and tables:

    • demo: Contains tables that represent a space mission.
    • burstbank: Contains many tables that represent a banking database.

    Create a catalog #

    To create a catalog with the sample dataset, select Data > Catalogs in the navigation menu and click Create catalog. Click the Sample dataset tile in the Select a dataset section.

    Define catalog name and description #

    The Catalog name 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 in the output of 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 schema context: 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.

    Enter catalog name and description

    Region #

    The Region field specifies the cloud provider region where you want the data stored. From the drop-down menu, choose the same region as the cluster that is to contain this dataset.

    Connect catalog #

    Click Connect catalog, and proceed to set permissions where you can grant access to certain roles.

    Set permissions #

    Use the following steps to assign read-only access to a specified set of roles:

    1. Select the Read-only catalog switch to grant a set of roles read-only access to the catalog’s schemas, tables, and views. For catalogs that are pre-set to read-only, this switch is already set and is disabled.
    2. Next, use the drop-down menu in the Role-level permissions section to specify the roles that have read-only access.
    3. Click Save access controls.

    A catalog created from this dataset exists by default in an example cluster on most Starburst Galaxy accounts. You can add this dataset to any other cluster if you find it useful.

    The example cluster on Galaxy accounts created before August 30, 2023 is named sample. For accounts created after that date, the example cluster is named free-cluster.

    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.

        Add to cluster

    Newly created Galaxy accounts have a query editor tab populated with two ready-to-run SQL queries that illustrate the use of this sample dataset.

    SQL support #

    The catalog provides read access to data and metadata in the sample dataset. It supports the following features:
