Enable auto re-attachment of rules

This guide explains how to configure your Snowflake environment to enable automatic reattachment of rules in Atlan.

Prerequisites​

Make sure the following conditions are met:

  • The recreated asset has the same name and similar structure.
  • The original rule is still present and not deleted.
  • The feature is enabled for your tenant.

Grant privileges​

Below are the minimum privileges the atlan_dq_service_role role needs to reattach rules automatically. Replace <database-name> and similar placeholders with your own object names.

  1. Database and schema usage: Enables Atlan to discover and reference objects.
GRANT USAGE ON DATABASE <database-name> TO ROLE atlan_dq_service_role;
GRANT USAGE ON ALL SCHEMAS IN DATABASE <database-name> TO ROLE atlan_dq_service_role;
  1. Table and view reference: Required for rules that reference columns in these objects.
GRANT REFERENCES ON ALL TABLES IN DATABASE <database-name> TO ROLE atlan_dq_service_role;
GRANT REFERENCES ON ALL VIEWS  IN DATABASE <database-name> TO ROLE atlan_dq_service_role;
  1. DMF schema and function usage: Enables execution of Snowflake Data Metric Functions created by Atlan.
-- Grant usage on the helper database / schema holding DMF functions
GRANT USAGE ON DATABASE ATLAN_DQ_DQ TO ROLE atlan_dq_service_role;
GRANT USAGE ON SCHEMA   ATLAN_DQ_DQ.DMFS TO ROLE atlan_dq_service_role;

-- Grant usage on all existing and future functions within the DMF schema
GRANT USAGE ON ALL FUNCTIONS    IN SCHEMA ATLAN_DQ_DQ.DMFS TO ROLE atlan_dq_service_role;
GRANT USAGE ON FUTURE FUNCTIONS IN SCHEMA ATLAN_DQ_DQ.DMFS TO ROLE atlan_dq_service_role;
  1. Future-proofing privileges: Ensures newly created objects are covered without manual grants.
GRANT USAGE      ON FUTURE SCHEMAS  IN DATABASE <database-name> TO ROLE atlan_dq_service_role;
GRANT REFERENCES ON FUTURE TABLES   IN DATABASE <database-name> TO ROLE atlan_dq_service_role;
GRANT REFERENCES ON FUTURE VIEWS    IN DATABASE <database-name> TO ROLE atlan_dq_service_role;

After these grants are applied, any table or view that's recreated with the same name automatically regains its attached rules, keeping your data quality checks continuous.

What’s next​

Once privileges are configured, rule reattachment happens automatically whenever matching assets are recreated in Snowflake. You can now continue monitoring your data quality workflows without needing to manually reapply rules.
