Latest CAP Theorem Articles

The CAP theorem describes a fundamental constraint in distributed data systems : during a network partition, a system cannot guarantee both strong consistency and full availability for every request.

CAP theorem defines three guarantees in distributed systems: consistency , availability , and partition tolerance, with the constraint that only two can be fully satisfied during a network partition. In real-world architectures, partition tolerance is unavoidable, which forces systems to choose betw

Consistency in system design describes how fresh and correct data should be when users, services, or replicas read it after a write. Some systems require every read to reflect the latest committed value, while others can tolerate stale data for better latency, availability, or scalability.
