Otomatik ağırlık atamasıyla bir veritabanı uç noktası yapılandırdığınızda ApsaraDB RDS for PostgreSQL, her salt-okunur örneğe örnek türüne dayalı bir okuma ağırlığı atar. Ağırlıklar, her örneğin alacağı okuma trafiğinin oranını belirler; örneğin 800 ağırlığa sahip bir örnek, 400 ağırlığa sahip bir örneğin iki katı okuma trafiği alır.
Aşağıdaki tablolar örnek türlerine göre varsayılan ağırlıkları listeler.
