By clicking on the Finish button, it will create the Datastore and skipping the configuration of an Enrichment Datastore.

  • To configure an Enrichment Datastore in another moment, please refer to this section

Note

It is important to associate an Enrichment Datastore with your new Datastore

  • The Enrichment Datastore will allow Qualytics to record enrichment data, copies of the source anomalous data and additional metadata for your Datastore

Configuring an Enrichment Datastore

  • If you have an Enrichment Datastore already setup, you can link it by enable to use an existing Enrichment Datastore and select from the list

  • If you don't have an Enrichment Datastore, you can create one at the same page:

Snowflake Qualytics Warehouse required

Create a Warehouse

  1. To create a warehouse with minimum requirements, you can use the following command:

        CREATE WAREHOUSE qualytics_wh
    WITH
        WAREHOUSE_SIZE = 'XSMALL'
        AUTO_SUSPEND = 60
        AUTO_RESUME = TRUE;

  2. To give a specific warehouse as the default for a user:

        ALTER USER <username> SET DEFAULT_WAREHOUSE = qualytics_wh;

Datastore Snowflake privileges permissions required

Creating a Custom Read-Only Role

  1. Create a new role called qualytics_read_role by running the following command:

        CREATE ROLE qualytics_read_role;
    GRANT USAGE ON WAREHOUSE qualytics_wh TO ROLE qualytics_read_role;

  2. Grant the USAGE privilege on the database, specific schema and table to the qualytics_read_role by running the following command:

        GRANT USAGE ON DATABASE <database_name> TO ROLE qualytics_read_role;
    GRANT USAGE ON SCHEMA <database_name>.<schema_name> TO ROLE qualytics_read_role;
    GRANT SELECT ON TABLE <database_name>.<schema_name>.<table_name> TO ROLE qualytics_read_role;

    GRANT SELECT ON ALL TABLES IN SCHEMA <database_name>.<schema_name> TO ROLE qualytics_read_role;
    GRANT SELECT ON ALL VIEWS IN SCHEMA <database_name>.<schema_name> TO ROLE qualytics_read_role;

    GRANT SELECT ON FUTURE TABLES IN SCHEMA <database_name>.<schema_name> TO ROLE qualytics_read_role;
    GRANT SELECT ON FUTURE VIEWS IN SCHEMA <database_name>.<schema_name> TO ROLE qualytics_read_role;

  3. Assign the qualytics_read_role to the desired user by running the following command:

        GRANT ROLE qualytics_read_role TO USER <user_name>;

Enrichment Datastore Snowflake privileges permissions required

Creating a Custom Read-Write Role

  1. Create a new role called qualytics_readwrite_role by running the following command:

        CREATE ROLE qualytics_readwrite_role;
    GRANT USAGE ON WAREHOUSE qualytics_wh TO ROLE qualytics_readwrite_role;

  2. Grant the USAGE and MODIFY privileges on the enrichment schema within the specific database and schema to the qualytics_readwrite_role by running the following command:

        GRANT USAGE, MODIFY ON DATABASE <database_name> TO ROLE qualytics_readwrite_role;
    GRANT USAGE, MODIFY ON SCHEMA <database_name>.<qualytics_schema> TO ROLE qualytics_readwrite_role;
    GRANT CREATE TABLE ON SCHEMA <database_name>.<qualytics_schema> TO ROLE qualytics_readwrite_role;
    GRANT SELECT ON FUTURE VIEWS IN SCHEMA <database_name>.<qualytics_schema> TO ROLE qualytics_readwrite_role;
    GRANT SELECT ON FUTURE TABLES IN SCHEMA <database_name>.<qualytics_schema> TO ROLE qualytics_readwrite_role;
    GRANT SELECT ON ALL TABLES IN SCHEMA <database_name>.<qualytics_schema> TO ROLE qualytics_readwrite_role;
    GRANT SELECT ON ALL VIEWS IN SCHEMA <database_name>.<qualytics_schema> TO ROLE qualytics_readwrite_role;

  3. Assign the qualytics_readwrite_role to the desired user by running the following command:

        GRANT ROLE qualytics_readwrite_role TO USER <user_name>;
