    AnalyticDB:Instance resource configuration

    Last Updated:Jun 05, 2026

    Instances of AnalyticDB for PostgreSQL in serverless automatic scheduling mode automatically pause and resume based on traffic. You can configure a serverless automatic scheduling instance's Computing Resource Threshold and Wait Time for Idle Resource Release to reduce costs. If an instance has no traffic for a specified period, it automatically enters the idle state. You are not charged for compute resources while the instance is in the idle state.

    Prerequisites

    The instance is in serverless automatic scheduling mode.
