Idempotency: Why 'Just Retry It' Breaks More Than It Fixes
Idempotency is a critical concept in system design. Understanding the implications of retries is essential for avoiding errors.
When a payment request is sent and the network hiccups, the client may retry, leading to potential double charges. This highlights the importance of idempotency, where an operation should leave the system in the same state regardless of how many times it is executed. Understanding and implementing idempotency is crucial in system design to avoid such issues.
