I think that should be a separate lira. This feature does a very simple
thing, it allows for a use to provide a function in the format JsonObject
parse(rawMessage) in a language of his choice. The concept is that he can now
use standard library functions to parse the rawMessage into JSon, which metron
can then use.
dependencies for external libraries i think will need to be tested. This
could be the strategy...
1. For JS script, you could just include the min.js link or just put your
script in a http server and refer it in the script.
2. For groovy script, could be as simple as dropping a jar in the proper
location, i guess the bolt class path.
3. for python, i think we should be able to put the modules in a modules
folder and i think python script can refer to it from there, we will have to
look at that packaging.
I think it is a little more complicated and i think a separate would be
needed to track it.
