[erlang-questions] Postgresql vs Mnesia vs Couchdb

Dynomite is a Dynamo clone written mostly in Erlang: 
http://github.com/cliffmoon/dynomite

Your question about benchmarks and scalability is rather vague.  Are you 
looking for throughput, availability, reliability, or some other 
factor?  Also, you cite three very different databases, that have 
different purposes.  I think a better question would be "which one is 
appropriate for the application I'm building?"

Cheers,

Sean
