-
Object Metadata
Objects in Cloud Storage are stored with additional metadata, including custom metadata that you define.
-
Cloud Pub/Sub Notifications for Cloud Storage
Cloud Pub/Sub Notifications record changes to objects in your Cloud Storage buckets.
-
Object Change Notification
The Object Change Notification feature of Cloud Storage allows you to actively monitor object changes and additions to a bucket.
-
Object Versioning

The Requester Pays feature enables costs for accessing buckets and objects to be billed to a requester-specified project instead of the project of the bucket being accessed.
-
Retention Policies and Bucket Lock
Retention policies prevent objects within your buckets from being modified or deleted for a set period of time. Bucket locking irreversibly prevents your retention policies from being reduced or deleted.

An overview page presenting the different methods you can use to control access to your buckets and objects.
-
Identity and Access Management
Identity and Access Managament allows you to control who has access to your buckets and objects.
-
Bucket Policy OnlyBETA
