Configuring a Graceful Scale-In Policy

You can set a graceful scale-in time window to save important data before a component instance stops. The value ranges from 0 to 9999, in seconds. The default value is 30. For example, if an application has two instances and only one instance will be kept after the scale-in operation, you can still perform certain operations on the instance to be stopped in the specified time window.

Prerequisites

Graceful scale-in policies can be configured only for container-deployed components in the Running or Not ready state. For details about how to check the component status, see Viewing Component Details.
