cap theorem

CAP theorem states that it is impossible for a distributed system to provide more than two of these guarantees: consistency, availability, and partition tolerance.

• Consistency
  • All clients see the same data at the same time from any node

• Availability

  • The ability for a system to respond to requests from users at all times

  

• Partition Tolerance

  • The ability for a system to continue operating even if there is a partition in the network
