GenStage in the Kitchen
summary
GenStage models a restaurant as a demand driven pipeline in Elixir where tables are external event sources, a waiter acts as a producer with a broadcast dispatcher, the chef is a producer_consumer using a partition dispatcher, and line cooks are consumers. The claim is concrete: backpressure pushes load upstream so slow chef behavior builds a waiter queue while line cooks stay unaffected. A visual simulation with four tables runs live, demonstrates queue growth when the chef slows, and recovers when line cook capacity increases.
