A deep dive into building resilient, high-throughput cancellation systems — from delay queues and Redis expirations to distributed schedulers
Disclosure: I use GPT search to collect facts. The entire article is drafted by me.
Introduction
Many e-commerce applications struggle with a seemingly simple requirement: automatically canceling unpaid orders after a set period. Having architected payment systems that process millions of transactions daily, you need to know how this “simple” feature can bring down entire platforms when implemented poorly. In this deep dive, I’ll share approaches to building resilient order cancellation systems that can scale from startup to enterprise level.

Order auto-cancellation is fundamentally about consistency and timing: when a user doesn’t complete payment within a designated timeframe (typically 30 minutes), the system must automatically cancel that order, release inventory, and potentially notify the customer.
