What is the CAP theorem? How useful is it to system design?

The CAP theorem is a concept in computer science that explains the trade-offs between consistency, availability, and partition tolerance in distributed systems.

Consistency refers to the property of a system where all nodes have a consistent view of the data. It means all clients see the same data at the same time, no matter which node they connect to.

Availability refers to the ability of a system to respond to requests from users at all times.

Partition tolerance refers to the ability of a system to continue operating even if there is a network partition.
