Two major generalizing variants of CO exist, Extended CO (ECO; Raz 1993a) and Multi-version CO (MVCO; Raz 1993b), which as well provide global serializability, also when combined with any relevant concurrency control, and allow optimistic (non-blocking) implementations.
Two major generalizing variants of CO exist, Extended CO (ECO; Raz 1993a) and Multi-version CO (MVCO; Raz 1993b). They as well provide global serializability without local concurrency control information distribution, can be combined with any relevant concurrency control, and allow optimistic (non-blocking) implementations.
