    Multiversion concurrency control (MCC or MVCC), is a concurrency control method commonly used by database management systems to provide concurrent access to the database and in programming languages to implement transactional memory. See more

    Description

    Without concurrency control, if someone is reading from a database at the same time as someone else is writing to it, it is possible that the reader will see a half-written or inconsistent piece of data. For instance, when … See more

    History

    Multiversion concurrency control is described in some detail in the 1981 paper "Concurrency Control in Distributed Database Systems" by Phil Bernstein and Nathan Goodman, then employed by the Computer Corporation of America. Bernstein and … See more

    Implementation

    MVCC uses timestamps (TS), and incrementing transaction IDs, to achieve transactional consistency. MVCC ensures a transaction (T) never has to wait to Read a database object … See more

    Examples

    Concurrent read–write
    At Time = 1, the state of a database could be:
    T0 wrote Object 1="Foo" and Object 2="Bar". After that … See more

    https://de.wikipedia.org/wiki/Multiversion_Concurrency_Control

    Multiversion Concurrency Control (MCC, MVCC, multi-generational concurrency control) ist ein Verfahren aus der Datenbanktechnik, das dazu dient, konkurrierende Zugriffe auf eine Datenbank möglichst effizient auszuführen, ohne zu blockieren oder die Konsistenz der Datenbank zu gefährden.
    Dabei wird sichergestellt, dass eine Transaktion nie auf Datenbankobjekte warten muss. Zu dies…

      • MVCC usa marcas de tiempo o identificadores de transacción crecientes para conseguir consistencia transaccional. Asegura que ninguna transacción tenga que esperar por un objeto de la base de datos a base de mantener varias versiones de ese objeto. Cada versión tiene asociada su marca de tiempo de escritura por el que permite leer a una transacción ...

        • MVCC utilise des marqueurs temporels (timestamp - estampille) ou incrémente des identifiants de transaction pour mettre en œuvre des transactions consistantes. MVCC assure qu'une transaction n'aura jamais à attendre la disponibilité d'un objet en gérant plusieurs versions de chaque objet. Chaque version de ligne dispose d'une estampille et laiss…
