Brewer's theorem
Quizzes for review
(computing theory) A theorem stating that it is impossible for a distributed data store to simultaneously provide more than two of three guarantees: consistency (every read receives the most recent write or an error), availability (every request receives a non-error response, without the guarantee that it contains the most recent write), and partition tolerance (the system continues to operate despite an arbitrary number of messages being dropped or delayed between nodes).
Brewer's theorem
When designing a distributed database, engineers often invoke Brewer's theorem to decide whether to favor consistency, availability, or partition tolerance.
