Saga compensation ordering
In a saga (charge -> reserve -> ship), ship fails. In what order should compensations execute?
Options
- 1Forward order, repeating each completed step, so the saga re-applies the actions it ran
- 2Reverse order of forward steps, undoing each completed action backwards
- 3Only refund the payment, since the other steps auto-expire with no compensator
- 4Random order, since saga steps are independent and each compensator runs in any sequence
