You can group in a collection folder CVDs that share a logical relation to other CVDs. Additionally, you can change an upload policy to a CVD collection with a single action.
For example, you can aggregate all CVDs of users in the marketing department to a folder under a collection called Marketing. Then you can change with a single action the upload policy that all the Marketing CVDs share.
Mirage supports static and dynamic collections. You manually assign CVDs to a static collection, while CVD assignments to dynamic collections are calculated based on predefined filters every time an operation is applied to a collection.
A CVD can be a member of multiple collections. If different base layers or policies are applied to different collections and a CVD belongs to more than one, the last change applied takes effect.
