On Twitter every tweet has an int64 id assigned to it, but is it generated randomly? And if so, is it possible to have two tweets with the exact same id? I know 2^64 is a large number, but I just want to know if twitter has a way of preventing two tweets with the same id or do they rely on the fact that 2^64 is such a large number and having two of the same id's is an extremely small chance?
