Someone want to implement something like that without 100 jars of dependencies and 8Gb of memory required to just run, in old-fashioned C/Lisp way (or more modern nginx-way)? Update: on top of Plan9?! ^_^
Storm does not have 100's of jars of dependencies, nor does it require much memory to run. In fact, it's quite straightforward to spin up a Storm cluster (see https://github.com/nathanmarz/storm/wiki/Setting-up-a-Storm-... ) and Storm has a local mode where you can develop/test topologies on your local mode completely in-process.
Or, at least, in more suitable Erlang? ^_^
Isn't it an obvious startup-idea?
