The CAT Theorem and Performance of Transactional Distributed
... The CAP theorem was originally intended for CRUDsupporting NoSQL systems. To warm up discussion leading to our CAT theorem, we discuss an analogy between the CRUD/NoSQL world and the transactional/NewSQL world. First, we argue that abort rates are important to consider in transaction systems because ...
