What problem does it solve?

Prevents duplicate side effects on retried write requests by introducing idempotency keys and a dedup store.

Core Features & Use Cases

  • Classify operations by idempotency needs and apply the appropriate contract.
  • Define a stable Idempotency-Key header, TTL policy, and tenant-scoped key design.
  • Choose a dedup store (Redis, DynamoDB, or a relational table) and ensure atomic claim-then-commit.
  • Store the full response for byte-equal replay and enable observability on dedup hit-rates.

Quick Start

Define an Idempotency-Key header for action-like POST endpoints and implement an atomic dedup store with a replayable response contract.
