hi, i think this discussion (partly fueled by the current twitter discussions?) is not in any way productive. couchdb is a wonderful database and erlang is a language it happens to be written in, who cares if oracle is written in C++? erlang and the erlang vm are just part of the product couchdb, if you want to hack it, learn erlang, if you want to use it, javascript might be enough. a database is nothing you normally deploy on your JVM, at least i don't.
having said that i think that scala may be an interesting approach to get all those poor java guys into something more exciting, however i think it goes nowhere near as far as erlang in many respects. cheers lenz On Tue, Apr 7, 2009 at 11:21 PM, Robert Dionne <[email protected] > wrote: > I would imagine Scala is interesting for those with an existing commitment > to a large legacy base of Java code.
