hi Frank, we are definitely not entirely on top of this stuff, but it is very awesome and we will get there eventually :) Can you help me understand where we went awry here: "Now of course the problem there with a rules engine... I have to look at the incremental dataflow, but I imagine it's kind of the same sort of approach. The problem with that is that if you want to sort by a new thing or you have a new piece of information, you have to change the network and backflow any... [You have to know compile time...] Yeah. Yeah. Exactly. And there are systems where you can add a new rule at runtime, but a lot of those also involve then re-ingesting history into the network to repopulate anything they... 'Cause a lot of these systems to save memory, will just throw away any information you're not interested in, from compiled query." If we are close can you tighten up the language and if we are far where did we go wrong? (In the context of differential dataflow, not rules networks)
