PACELC design principle
open-in-new
<p>In <a href="/facts/Database_theory/unyQa3cK">database theory</a>, the PACELC design principle is an extension to the <a href="/facts/CAP_theorem/qnxvcbLp">CAP theorem</a>. It states that in case of network partitioning (P) in a distributed computer system, one has to choose between availability (A) and consistency (C) (as per the CAP theorem), but else (E), even when the system is running normally in the absence of partitions, one has to choose between latency (L) and loss of consistency (C). </p>
