How do you keep async workflows understandable as they grow? - Mxstermind - 10-26-2026

A workflow can start simple: receive a request, process it and return a result.

Then it grows to include external APIs, retries, rate limits, human approvals and scheduled actions.

At that point, I find explicit state transitions and observable job histories more useful than clever abstractions.

How do you structure long-running workflows in Java? Do you prefer a state machine, event-driven architecture or a straightforward queue with persisted job states?
