Setting Off a Cloud Function via Cloud Storage Metadata
While Cloud Functions can be triggered by major Cloud Storage events, like an object being created or deleted, the function can also be executed on changes to various aspects of the object's status, as represented by updates to its metadata. In this hands-on lab, you'll create a Cloud Function with a Cloud Storage trigger that watches for changes to a bucket's objects’ metadata and outputs the result of that change.
