package awscdk


// Specifies whether an Auto Scaling group and the instances it contains are replaced during an update.
//
// During replacement,
// AWS CloudFormation retains the old group until it finishes creating the new one. If the update fails, AWS CloudFormation
// can roll back to the old Auto Scaling group and delete the new Auto Scaling group.
//
// While AWS CloudFormation creates the new group, it doesn't detach or attach any instances. After successfully creating
// the new Auto Scaling group, AWS CloudFormation deletes the old Auto Scaling group during the cleanup process.
//
// When you set the WillReplace parameter, remember to specify a matching CreationPolicy. If the minimum number of
// instances (specified by the MinSuccessfulInstancesPercent property) don't signal success within the Timeout period
// (specified in the CreationPolicy policy), the replacement update fails and AWS CloudFormation rolls back to the old
// Auto Scaling group.
//
// Example:
//   // The code below shows an example of how to instantiate this type.
//   // The values are placeholders you should change.
