Postgres MVCC

5. Concurrency Control :: Hironobu SUZUKI @ InterDB

Concurrency Control is a mechanism that maintains atomicity and isolation, which are two properties of the ACID, when multiple transactions run concurrently in a database.

Multi Version Concurrency Content의 약자로, 여기서 Multi Version 은 하나의 레코드에 여러 버전이 관리된다는 의미이다. 데이터베이스 관리 시스템이 일반적으로 사용하는 동시성 제어 방식으로 데이터베이스로의 동시 접근( 잠금을 사용하지 않는 일관된 읽기)을 제공한다. MVCC를 사용하면 Locking 메커니즘이 불필요함에도 불구하고 오라클 등 일부 MVCC 데이터베이스에서는 Lock을 사용한다.
