Hi John, in your setup the two flows between the broadcast and the zip must always be perfectly balanced, if one of them may lose elements then eventually the whole graph will get stuck. Either you make sure that failure does not happen (and when it does you don’t restart but kill the whole stream because you know that it will be broken and needs to be recreated) or you make up elements on demand, e.g. using the expand() combinator. The second possibility leads to non-deterministic behavior, though: it is not predetermined which element will be expanded exactly.
A buffer does not help in this scenario. The difference in the “balancing buffer” blog post is that elements are distributed dynamically to the branches whereas here you want to always feed every input into all branches.
