Automatically Process Cloud Storage Uploads with Change Notifications





Do your customers upload files to Google Cloud Storage for your applications to process? For example, a photo app may want to create thumbnails of new images as soon as they are uploaded. Normally you would have to poll for updated objects which can be a resource waste or cause you to react slowly. Most times writing and deploying custom scripts to trigger your application is cumbersome.



Today, we're releasing object change notification as a preview feature, allowing you to monitor your Google Cloud Storage buckets for new, modified, or deleted objects, using a subscription to a webhook you provide. Now your application can be automatically triggered when an important change happens and start processing data immediately. We've also updated gsutil with a notifyconfig command. A Google App Engine webhook can be as simple as the following:








We're also releasing an update to the Google Cloud Storage JSON API, bringing it into parity with our existing XML API, including exposing new methods such as Copy and Compose. As a part of this release, we are making the API available to everyone without requiring an invitation.






Enjoy, and as always, we watch StackOverflow.
