Using Neo4j and MongoDB together in a CPython framework

Question

Well, here is my problem, I'll make an e-commerce project for my thesis, I'll make it using Django, and I wanna use NoSql solution, since I'll imagine that this e-commerce website will grow (...) the idea of that website is a social-e-commerce without money transactions, I'll use two solutions: MongoDB to store users information (since it's a schema-free) and Neo4j to make relations between users.

Ok, maybe someone will say: why not using Neo4j to handle everything since Neo4j is also a schema-free, but because it's Django, so I said that something that is a C-program will be better and faster for the web application than a 100% Java solution (when dealing with C-Django), I'll use CPython and not Jython, and I've installed JPype, so I imagine that calling Java from Python is something that will take time?

So my question is:

• is it better to use that solution: _id123456789012 is a (friend/best client/best seller...) with _id122234567890 as you can see the _id is generated from mongodb (the harder work) but only the relations are made using neo4j, so all the 80% of the work is done from mongoDB, or do i make everything with one of them: neo4j or mongo?

• second, if the solution of using both, how about scaling? from the graph that speaks about NoSql it seems that Neo4j is the latest in Scaling in size (while the best in Scaling in complexity) so will there a problem of "synchronizing"?
