Overview


CAP Theorem

The CAP theorem, also known as Brewer’s theorem, states that it is impossible for a distributed computer system to simultaneously provide all three of the following guarantees:

  • Consistency (all nodes see the same data at the same time)

  • Availability (node failures do not prevent survivors from continuing to operate)

  • Partition Tolerance (the system continues to operate despite arbitrary message loss)
