 | PostgreSQL은 Red Hat Enterprise Linux와 함께 사용되는 매우 정교하고 강력한 데이터베이스 서버입니다. 하지만, 많은 이들이 MySQL의 메모리 스토리지 엔진이 빠져 있다는 점에 대해 문제를 제기하곤 합니다. 스토리지 엔진은, 드물게 업데이트되지만 빈번히 액세스가 이루어지는 임시 데이터를 처리하는 애플리케이션에 특히 이상적이라 할 수 있습니다. 이들 애플리케이션은 메모리에 저장된 데이터베이스를 사용하여 디스크 오퍼레이션의 수를 줄여 주는데, 이러한 애플리케이션의 예로 웹 기반의 BitTorrent Tracker를 들 수 있습니다. 팁에서는 PostgreSQL 데이터베이스 서버 자체와 Red Hat Enterprise Linux 운영체제가 제공하는 표준 기능을 사용하여 PostgreSQL의 메모리 스토리지를 설정하는 방법에 대해 알아보도록 하겠습니다. |

 | PostgreSQL 데이터베이스 서버와 관련하여 메모리 스토리지를 설정하는 방법에 대해 알아보았습니다. PostgreSQL의 모든 기능 이외에도, 메모리 데이터베이스를 사용할 경우 MySQL에서와 같은 제한 사항은 발생하지 않습니다. 완벽한 설정을 위해서 임의대로 init 스크립트를 손보아야 할 수도 있습니다.
