CAP Theorem (Consistency, Availability, Partition)

06 Apr

CAP theorem states that it’s impossible for a distributed computer system to have all the following simultaneously

  • Consistency
    All part of the systems see the same data.
  • Availability
    A guarantee that each request receives a response regardless of success / failure.
  • Partition tolerance
    The whole system continue to work despite disconnection, message loss or any failure in the subsystems.

Eric Brewer said that a distributed computer system can only have 2 out of these 3 functions at a time.
