MVCC Unmasked

Date: 2022-10-27
Time: 13:40–14:30
Room: Berlin 1
Level: Advanced

Multi-Version Concurrency Control (MVCC) allows Postgres to offer high concurrency even during significant database read/write activity. MVCC specifically offers behavior where "readers never block writers, and writers never block readers". This talk explains how MVCC is implemented in Postgres and highlights optimizations which minimize the downsides of MVCC.
