Read/Write NetworkX Graph Object

Question

I am trying to deal with a super-massive NetworkX Graph object with hundreds of millions of nodes. I\'d like to be able to write it to file as to not consume all my computer mem

Answer 1

I forgot what problem I came to StackOverflow to solve originally, but I stumbled on this question and (nearly a decade too late!) can recommend Grand, a networkx-like library we wrote to solve exactly this problem:

Before

import networkx as nx

g = nx.DiGraph()
g.add_edge("A", "B")
print(len(g.edges()))

After

import grand
from grand.backends import SQLBackend # or choose another!

g = grand.Graph(backend=SQLBackend())
g.nx.add_edge("A", "B")
print(len(g.nx.edges()))

The API is the same as NetworkX, but the data live in SQL, DynamoDB, etc.
