CAP Twelve Years Later: How the "Rules" Have Changed

CAP Twelve Years Later: How the "Rules" Have Changed: "In its classic interpretation, the CAP theorem ignores latency, although in practice, latency and partitions are deeply related. Operationally, the essence of CAP takes place during a timeout, a period when the program must make a fundamental decision-the partition decision:

cancel the operation and thus decrease availability, or

proceed with the operation and thus risk inconsistency."

CAP Twelve Years Later: How the "Rules" Have Changed

CAP Twelve Years Later: How the "Rules" Have Changed: "The CAP theorem states that any networked shared-data system can have at most two of three desirable properties:

consistency (C) equivalent to having a single up-to-date copy of the data;
high availability (A) of that data (for updates); and
tolerance to network partitions (P).

CAP theorem - Wikipedia, the free encyclopedia

CAP theorem - Wikipedia, the free encyclopedia: "In theoretical computer science, the CAP theorem, also known as Brewer's theorem, states that it is impossible for a distributed computer system to simultaneously provide all three of the following guarantees:[1][2]
Consistency (all nodes see the same data at the same time)
Availability (a guarantee that every request receives a response about whether it was successful or failed)
Partition tolerance (the system continues to operate despite arbitrary message loss or failure of part of the system)"
