I'm trying to understand your proposed system (as a non CS person). Would this be an accurate (basic) description of it? - You keep a deterministic log of all data inputs / transactions that should take place (a write-ahead log of sorts) that all workers can refer to. - Each worker remembers the position in the log that it has processed so far. - If a worker crashes during a transaction it can simply pick up at the position it was at before (possibly after doing some local cleanup) and replay the transactions.
