> This is a request to reduce the number of I/O's performed when objects are
> loaded into caches. Today, the list of roles is read from Metadata every time
> any object is placed into NATable and NARoutine cache. Since the list of
> roles associated with the current user is the same independent of the object
> being referenced, redundant I/O's are performed. The list of roles does
> change whenever a grant or revoke role is performed against the user, so the
> solution must make sure grant and revoke operations are handled correctly.
