Is there any dynamic configuration service in GCP ecosystem which the apps can integrate with, and get the capability to reflect any configuration changes at runtime. (i.e the config service pushes the changes to the application layer as soon as any change is made).
In the past, have seen a similar solution (built on top of apache zookeeper), thus want to explore if something similar exists within GCP as a service.
PS : Bounded eventual consistency of configurations across all app boxes is a must (max delay 5 seconds).
