Hi，[~abhayk]，In the source code，I can't understand how to optimize the memory
space。

> Trie structure is devised to index tagged entities and policies for a fast
> look-up. However, it may be take a lot of memory. This is a result of a
> design decision to optimize processing (mainly searching) time at the cost of
> extra memory.
> It is desirable to find a more optimal trade-off between memory needs and
> processing requirements, especially for supporting a large number or policies
> and tagged entities.
