Idempotency

Definition

Repeat request has same effect as one; duplicate orders or state avoided; use Idempotency-Key.

As defined in the knowledge graph

  • Re-running produces same result; required for reliable batch and streaming. — From: Data Engineering: Batch vs Streaming In-Depth
  • Processing same message twice produces same result; use idempotency key or MessageId to deduplicate. — From: Event-Driven Architecture on Azure
  • Command ID or idempotency key so duplicate submissions do not double-apply. — From: Event Sourcing and CQRS: Patterns, Bus, Unit of Work, and Resilience
  • Processing same action twice yields same result; critical for points and badges; use idempotency key. — From: Gamification in Enterprise Applications
  • Property that repeating an operation has same effect as once; retry-safe when idempotent. — From: Microservices Resilience: Circuit Breaker, Retry, Timeout, Bulkhead, and Fallback
  • When integrating with TDP schemes; duplicate submissions must not double-register. — From: Property Management Systems in the UK: Tech and Compliance
