Fast Serializable Multi-Version Concurrency Control for Main-Memory Database Systems
Thomas Neumann, Tobias Mühlbauer, Alfons Kemper · 2015
Multi-Version Concurrency Control (MVCC) is a widely employed concurrency control mechanism, as it allows for execution modes where readers never block writers. However, most systems implement only snapshot isolation (SI) instead of full serializability. Adding serializability guarantees to existing SI implementations tends to be prohibitively expensive.
