Subject Re: How can build Bond graph?

I certainly don't think it would be a problem, but your use case ("social network") is very
vague. If you described particular operations that you're concerned about, we might be able
to either better assuage your fears, or offer coherent suggestions for alternative strategies.

Another good thing you could do, is to go and build a simplified prototype and run some synthetic
performance tests on it to identify specific problem areas.
