An illustrated proof of the CAP theorem (2018)

  • The CAP Theorem in distributed systems posits that a system can only achieve two out of three properties: Consistency, Availability, and Partition Tolerance.- Consistency ensures that any read after a write returns the latest value, Availability guarantees responses from non-failing nodes, and Partition Tolerance allows operation despite network message losses.- The theorem, proven by Gilbert and Lynch, demonstrates that a system cannot maintain all three properties simultaneously, as network partitions can lead to inconsistencies.

Reactions

  • The CAP theorem explains that in distributed systems, only two of the three properties—Consistency, Availability, and Partition Tolerance—can be achieved simultaneously.- The PACELC theorem builds on CAP by stating that in the absence of partitions, a choice must be made between Latency and Consistency.- Systems like Google Spanner use advanced protocols and precise clocks to maintain consistency, illustrating the trade-offs in system design.
