Elucidate the concept of CAP theorem?

CAP is efficiently used at the time of handling and managing the scaling tactics. Whenever a desire of scaling is observed, CAP theorem play its vital role. CAP Theory stands for Consistency Availability and Partition tolerance theory which states that in the system same as Cassandra users cannot use all the three characteristics, they have to choose two of them and one is needed to sacrifice.

These three characteristics are: -

• Consistency: It gives the warranty for returning of recent write for the user.
