Transaction Rollback Logic
Updated 2026-08-10
INTRODUCTION
English translation pending.
CORE DEFINITION
When an operation fails, the system state is restored to what it was before the operation began: either everything succeeds, or everything is undone. As a scaffold it is safe failure handling: you may attempt an operation that could fail, because the failure can be undone, which lowers the cost of trying it in the first place.
SCAFFOLDING EFFECT
Reduce cognitive load
- Bundle up: put all of the related operations together inside one single transaction. - Old state saved: record exactly what the system looked like before you ever begin. - Any failure, full rewind: if any single step fails, undo the whole transaction at once.
Anchor fast decisions
This is the atomicity of ACID database transactions: a group of operations either all succeeds or fails and rolls back to the starting point. The mechanism is the undo log, which records the old value before the operation, so that an error can be reversed by applying it backward, making trial and error safe because failure can be undone.
