title: Huge Graph Structure
body: <p>I'm developing an application in which I need a structure to represent a huge graph (between 1000000 and 6000000 nodes and 100 or 600 edges per node) in memory. The edges representation will contain some attributes of the relation. </p>
  
  <p>I have tried a memory map representation, arrays, dictionaries and strings to represent that structure in memory, but these always crash because of the memory limit.</p>
  
  <p>I would like to get an advice of how I can represent this, or something similar.</p>
  
  <p>By the way, I'm using python.</p>
