How should I handle small tables on a cluster? (no replies)

I can understand how large tables get partitioned over the data nodes and that's exactly what I need, but I also have some small tables ( 20/30 records ) which are used for lookups - things like users/codes etc. The idea of this small number of records being spread across nodes seems a ridiculous idea and so I'm sure I'm missing something. I've tried searching - but there is so much about MySQL Cluster I can't find the bit I'm after.
So can someone please point me at how to solve this simple problem :)
Thanks
