>
> Time for building a Trie index for resources may become a bottleneck when
> dealing with large number of resources. It is desirable to build different,
> non-overlapping parts of Trie structure using multiple threads to reduce
> overall build time if configured to do so.
> Also, instead of building out all Trie nodes completely (that is, by
> propagating wildcard evaluators all the way to all leaves of Trie tree) at
> the initialization time, it is optimal to do so as a Trie-Node is accessed
> for the first time during resource lookup.
