AppEngine - Registry

Overview

The Registry is mainly responsible for

• installing / updating / storing apps
• uninstalling / removing apps
• getting apps

Asynchronous behavior

Both the install and the uninstall process are performed asynchronously. The Registry persists the app bundle and defines the desired state of the app (e.g. installed, uninstalled). The installation / uninstallation process is then handled asynchronously by a separate service.

The current status of the app is provided by the status in the response body of the respective GET request, e.g. /apps/{id}.
