Idempotency provides resilience against messages that might be repeated (e.g., at-least-once delivery).
Idempotent operations are also typically structured as absolute, not relative data.
For example, a bank might send a message "set balance to $100", not "subtract $10 from balance" - if the message is repeated, the correct result is still obtained.
