Abstract

The CAP theorem's impact on modern distributed database system design is more limited than is often perceived. Another tradeoff—between consistency and latency —has had a more direct influence on several well-known DDBSs. A proposed new formulation, PACELC, unifies this tradeoff with CAP.
