I strikes me (without knowing anything at all about your application) that
you might be better off using the normal erlang inter-node communication
mechansims to communicate changes to the database to the rest of your
system. I have seen table events used quite extensively in other database
environments but have never really felt the need to use them in Erlang
because there are usually much easier and more "native" ways to achieve the
same aim.

Good luck in your Erlanging
