WHY AREN'T YOU IDEMPOTENT?

Idempotency is important in distributed systems, particularly for low-latency APIs. It makes sure that repeated requests produce the same outcome as a single request, preventing unintended side effects from retries in unreliable networks. This author details techniques for creating idempotent endpoints, including client-supplied identifiers and timestamps and calibrated counters, using Apache Cassandra as a case study.
