About CFS buckets

Client File Store (CFS) facilitates buckets for use by publishers to organize file-sets and files. Buckets store metadata about the files stored in publisher-supplied repositories. Buckets align with subscriptions and can contain multiple file-sets and files.

Publishers are responsible for creating buckets with the CFS API. This is a one-time process. The resulting bucket is owned by one or more publishers and is assigned a unique name that cannot be assigned to another bucket. If a publisher provides more than one dataset, they can have multiple buckets.

Claims are used to control access to buckets, file-sets, and files. CFS does not manage or create claims, CFS only enforces them. Claims must be created in AAA. To access the bucket, subscribers must have at least one of the claims on the bucket.

Attributes are one of the methods that subscribers can use to filter and search for content.
