Excuse me, my bill does not match my order
In a distributed system messages sometimes get lost or duplicated. That's a fact of life. It is really hard to execute business logic that assumes one trigger equals one outcome when a trigger can be lost or fire twice.
One way of dealing with the problem is taking advantage of natural idempotency of some operations, e.g. adding element to a set. But let's face it, most code is more complex than that. Join me an explore some alternatives.
