CAP Theorem
• Cap theorem is also called as brewer's theorem.
• The CAP theorem is comprised of three components
(hence its name) as they relate to distributed data stores:
• Consistency: All reads receive the most recent write or an
error.
• Availability: All reads contain data, but it might not be
the most recent.
• Partition tolerance: The system continues to
operate despite network failures(i.e.; dropped partitions, slow network connections, or
unavailable network connections between nodes.)
• The CAP theorem states that it is not possible to
guarantee all three of the desirable properties - Consistency, availability and
partition tolerance at the same time in a distributed system with data
replication.
