defaultApplicationIdentifier

The unique identifier of the Amazon GameLift Streams application that you want to set as the default application in a stream group. The application that you specify must be in READY status. The default application is pre-cached on always-on compute resources, reducing stream startup times. Other applications are automatically cached as needed.

Note that this parameter only sets the default application in a stream group. To associate a new application to an existing stream group, you must use AssociateApplications.

When you switch default applications in a stream group, it can take up to a few hours for the new default application to be pre-cached.

This value is an Amazon Resource Name (ARN) or ID that uniquely identifies the application resource. Example ARN: arn:aws:gameliftstreams:us-west-2:111122223333:application/a-9ZY8X7Wv6. Example ID: a-9ZY8X7Wv6.
