We do all of the things you mention (minus the replay, but that would be trivial) in Clojure where I work, and it is remarkably easy. We use:
* ring + compojure and an embedded jetty server to create lightweight webservers * the Cheshire JSON encoding/decoding library for all JSON purposes (https://github.com/dakrone/cheshire) * we wrote our own small wrapper around rabbitmq - but there are several available now (such as https://github.com/michaelklishin/langohr) * for mongo we use: http://clojuremongodb.info/ We also found that when processing JSON messages, multimethods can be extremely useful as a dispatch mechanism if the shape of the JSON data dictates what should happen to it. I would certainly recommend Clojure for what you describe, I think you will be pleasantly suprised how straightforward it is :) On Tue, Sep 4, 2012 at 7:05 PM, Russell Whitaker <russell.whita...@gmail.com> wrote: > On Tue, Sep 4, 2012 at 4:45 PM, David Dawson > <david.daw...@dawsonsystems.com> wrote: >> Hiya! >> >> I saw the names, but then was swamped by moustache, noir and others that at >> first glance appear to be in similar spaces.
