No, you cannot clone users in the Snowflake. The two sets of objects that can be cloned are Data containment objects and Data configuration & Transformation objects.
Cloning the data using the concept of zero-copy clone snowflake, reproduces a schema, table, or database. When it is produced a snapshot is made accessible in the copied object by capturing it from the source object. Both the clone and the source object are not related to each other.
Clones help to create copies of any existing object in the system.
Transferring data from one database to another in Snowflake is possible using secure views. This can be only done when the database is owned by the same account. Objects such as tables, schemas, and others can be referenced from one database to another database using a secure view.
Currently, it is not possible to clone a transient table in Snowflake. It cannot be modified. The user cannot change a permanent table to a transient table and vice versa.
