    CAP theorem is known as Brewer's theorem. According to the CAP theorem, there are limitations for the NoSQL database. Against three guarantees of a database, only two can be achieved — consistency, availability and partition tolerance.

    CAP stands for Consistency, Availability and Partition tolerance. The CAP theorem is applied to a distributed system where only two desired characteristics will be delivered out of three. There is a different meaning of all CAP characteristics which are:

    • Consistency: There are different nodes connected to the system and under Consistency, every client will see the same data on the same time duration.
    • Availability: Even if the nodes are down under availability the client will get data responses for which they have requested.
    • Partition tolerance: A communication break in the distributed system is known as Partition where you can experience a temporary connection delay or loss between the nodes.
