Map is native data structure. However, you need to use enif interface to interact with it.

I’ve used to solve a “routing” issues on pure Erlang using ETS, lists, etc. However, this mainly depends on your traffic, latency and size of routing tables. It is hard to give a straight forward answer not knowing this figures.
