Cap Theorem

The CAP theorem, also known as Brewer's CAP theorem, is a fundamental concept in distributed systems that states it is impossible for a distributed data store to simultaneously guarantee more than two out of three characteristics: consistency, availability, and partition tolerance. Understanding the CAP theorem is crucial for tech professionals designing and developing distributed databases and systems, as it helps them make informed decisions about trade-offs between data consistency, system availability, and tolerance to network partitions, ultimately impacting the reliability and performance of their applications.
