You can create a subscribed library with the option to download the library content on demand. As a result, only the metadata for the library items is stored in the associated with the subscribed library storage. When you want to deploy a virtual machine from a VM temple in the subscribed library, you must synchronize the subscribed library to download the entire published library content. When you no longer need the VM template, you can call the

evict

function on the

SubscribedLibrary

service. You must provide the subscribed library ID to this function. As a result, the subscribed library content that is cached on the backing storage is deleted.

If the subscribed library is not configured to synchronize on demand, an exception is thrown. In this case the subscribed library always attempts to have the most recent published library content.
