> The implementation of SimplePrivilegeCache and in particular the 2
> map<String, Set<String>> fields, cachedAuthzPrivileges and wildCardAuthz is
> not memory efficient. The strings stored in these structures can be quite
> long e.g. (server=server1->database=b1,
> (server=server1->database=b1->action=insert)). For really big installations
> with lots of entities (roles and privileges) these fields may end up taking
> some non-substantial amount of memory.
> We should come up with of a more efficient memory representation to implement
> PrivilegeCache
