Usage notes¶

Latency for the view may be up to 120 minutes (2 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.
