Organization Usage performance
When you query a specific view in the SNOWFLAKE.ORGANIZATION_USAGE schema, follow the organization-wide guidance in
Performance (Organization Usage): bound every scan on history views, list
columns explicitly, and use the time filter column table plus worked SQL and anti-patterns there.
This Organization Usage view displays a row for each schema in an account except the READER_ACCOUNT_USAGE, and INFORMATION_SCHEMA schemas.

Usage notes¶
- Latency for the view may be up to 24 hours.
- The view only displays objects for which the current role for the session has been granted access privileges.
-
The LAST_ALTERED column is updated when the following operations are performed on an object:
- DDL operations.
- DML operations (for tables only). This column is updated even when no rows are affected by the DML statement.
- Background maintenance operations on metadata performed by Snowflake.
