After Graceful Scale-In is enabled, if the scale-in action is triggered when a node is executing tasks, the node will not be released immediately. Instead, it will be released after completing the tasks. Graceful Scale-In is available for both automatic scaling and manual scale-in.
Auto Scaling allows you to enable or disable Graceful Scale-In for all scale-in rules. This feature is called Global Graceful Scale-In and is disabled by default. When you add or edit a single scale-in rule, Graceful Scale-In is enabled by default, and the default duration is 60 seconds (valid range: 60-1800 seconds).
When Global Graceful Scale-In and a single rule are enabled, Graceful Scale-In takes effect for the rule.
When you try to manually remove a node, Graceful Scale-In is disabled by default. When you enable this feature, the default duration is 60 seconds (valid range: 60-1800 seconds).
