The splitting proces is mapreduce doing by parallel sessions for you. There is a control module to start it from your code (normal from a dashboard), but i don't now yet if the overhead is taken to much time. There are no docs yet. In the local development server some libraries are not there, see http://code.google.com/p/relat/wiki/python25 at the end. I'am also trying how far it get and where to use it. gr wim
