BETS May be a good template for MDB NIFs since the MDB API looks like bdb. It 
doesn't implement the Riak backend API but an ets subset.

Many thanks for all the helpful posts. BETS looks like a good starting point for a generic MDB driver in Erlang.

    Hi, I'm interested in developing a backend using OpenLDAP's memory-mapped
    database library (MDB). Unfortunately Erlang is not a language I've used
    before. Any tips on where to get started?

    You can find information on MDB here: http://highlandsun.com/hyc/__mdb/
    <http://highlandsun.com/hyc/mdb/>

    Its read performance is several times faster than anything else out there,
    and scales perfeclty linearly since readers require no locks. Its write
    performance is also quite fast...
