   > Before this, I think there's an issue worth discussing first: currently, 
all Entities retrieve the owner's Entity when obtaining the owner, which leads 
to unnecessary table join—for example, joining with the user table. However, in 
reality, GravitinoAuthorizer only needs the ownerId for authorization. We 
should consider how to optimize this issue.
