An application profile, or app profile, stores settings that tell your Cloud Bigtable instance
how to handle incoming requests from an application. When one of your applications connects to a
Cloud Bigtable instance, it can specify an app profile, and Cloud Bigtable uses that app profile
for any requests that the application sends over that connection.
App profiles affect how your applications communicate with an instance that uses replication.
As a result, app profiles are especially useful for instances that have 2 clusters. Even if your
instance has only 1 cluster, you can use a unique app profile for each application that you run,
or for different components within a single application.
