    Multiversion Concurrency Control (MVCC)
    Перевод технология MVCC, технология MVCC (Multiversion Concurrency Control, управление конкурентным доступом с помощью многоверсионности)
    Описание The main difference between multiversion and lock models is that in MVCC locks acquired for querying (reading) data don't conflict with locks acquired for writing data and so reading never blocks writing and writing never blocks reading. See concurrency control.
