Hi,

I am trying to use the REST API in order to generate graphs from python. It works fine :).

However, with the documentation available, I don't see how i can request efficiently for a Big Graph, let's say with 1 million of nodes.  
I'd like to get two iterators, one for the vertices and one for the edges. The same way as when I use the "scan" method from the low-level python client for querying documents.

Any idea ?

There is no streaming API, sorry.
