"The Role of the CAP Theorem in Shaping Big Data Technologies and Solutions"
The CAP theorem, also known as Brewer''s theorem, is a fundamental principle that guides the design and operation of distributed systems, particularly in the realm of big data. Formulated by computer scientist Eric Brewer, the theorem posits that a distributed system can only simultaneously guarantee two out of the following three properties:Consistency: Every read operation receives the most recent write or an error. In other words, all nodes in the system see the same data at the same time.Availability: Every request (read or write) receives a response, even if its not the most recent data. The system remains operational and responsive, regardless of the state of individual nodes.Partition Tolerance: The system continues to operate despite network partitions or communication breakdowns between nodes. In other words, the system can handle the loss of communication between parts of the network.
