Config path: /<database>/<schema>/params.yaml

Example:

retention_time: 7
is_sandbox: true

owner_schema_read:

owner_warehouse_usage:
  - my_warehouse

owner_integration_usage:
  - my_storage_integration

owner_account_grants:
  - EXECUTE ALERT

Schema

  • is_transient (bool) - make schema TRANSIENT

  • catalog (ident) - name of CATALOG used for Iceberg tables

  • owner_database_read (list)

    • {items} (ident) - grant READ privileges for objects in a database to OWNER role of this schema

  • owner_database_write (list)

    • {items} (ident) - grant WRITE privileges for objects in a database to OWNER role of this schema

    • {items} (ident) - grant READ privileges for objects in another schema to OWNER role of this schema

  • owner_schema_write (list)

    • {items} (ident) - grant WRITE privileges for objects in another schema to OWNER role of this schema

Usage notes

  1. File params.yaml is optional. All parameters are set to default if file is omitted.

  2. is_transient and retention_time are inherited from DATABASE object if omitted.

  3. Objects in database or schema marked with is_sandbox flag will not be dropped by SnowDDL if not defined in config.

  4. When defining custom permission_model, the ruleset of database permission_model and schema permission_model must be the same.

  5. owner_schema_read and owner_schema_write parameters are helpful when dealing with VIEWS and PROCEDURES, which require access to objects in another schemas. Usually only objects in the current schema are available to the OWNER role of this schema.

  6. owner_integration_usage parameter helps to provide additional USAGE privileges on various externally defined integration objects to schema OWNER role, which helps to resolve various permission-related issues. For example, it is required in order for error notification integrations to work properly.
