When she's discussing Compensations she mentions that the Transaction (T_i) can't have an input dependency on T_i-1. What are some things I should be thinking about when I have hard, ordered dependencies between microservice tasks? For example, microservice 2 (M2) requires output from M1, so the final ordering would be something like: M1 -> M2 -> M1.
Currently, I'm using a high-level, coordinating service to accomplish these long-running async tasks, with each M just sending messages to the top-level coordinator. I'd like to switch to a better pattern though, as I scale out services.
