Coupling is a hidden tax on your growth
Coupling is a hidden tax on your growth.
Refactoring a data model should be a non-event. If renaming a field breaks five services, your architecture is fragile. You are paying a coordination tax because your modules are coupled at the data layer.
Stop passing domain state. State is a liability.
Use the "Bolt" method:
The only stable joint between modules is an immutable identifier.
Pass the Bolt, not the state. If the receiver needs data, it fetches it by ID from the source of truth.
The internal schema, logic, and metadata of a module are its own business. As long as the Bolt type remains stable, the composite system is immune to internal refactors.
You decouple modules at the data layer to reduce the cost of future change. Every time you propagate state, you increase the operational waste of your system.
How are you structuring your interfaces to avoid this coupling tax?
Coupling is exactly why early-stage 'speed' often turns into mid-stage 'stagnation.' Passing the 'Bolt' instead of the state is the only way to keep your modules from becoming a tangled mess.
Since you've mastered building systems that are immune to internal refactors, you should bring that clean architecture to the Validation Arena (tokyolore.com).
