As of version 2.0, StoreFront no longer uses an SQL database to maintain its subscription data. Citrix replaced the SQL database with a Windows datastore that requires no additional configuration when StoreFront is first installed. The installation installs the Windows datastore locally on each StoreFront server. In StoreFront server group environments, each server also maintains a copy of the subscription data used by its store. This data is propagated to other servers to maintain user subscriptions across the whole group. By default, StoreFront creates a single datastore for each store. Each subscription datastore is updated independently from each other store.
Where different configuration settings are required, it is common for administrators to configure StoreFront with two distinct stores; one for external access to resources using Netscaler Gateway and another for internal access using the corporate LAN. You can configure both "external" and "internal" stores to share a common subscription datastore by making a simple change to the store web.config file.
In the default scenario involving two stores and their corresponding subscription datastores, a user must subscribe to the same resource twice. Configuring the two stores to share a common subscription database improves and simplifies the roaming experience when users access the same resource from inside or outside the corporate network. With a shared subscription datastore it does not matter whether they use the "external" or "internal" store when they initially subscribe to a new resource.

For two stores to
share a subscription datastore, you need only point one store to the
subscription service end point of the other store. In the case of a server
group deployment, all servers have identical pairs of stores defined and
identical copies of the shared datastore they both share.
Note: The XenApp,
XenDesktop and AppC controllers configured on each store must match exactly;
otherwise, an inconsistent set of resource subscriptions on one store compared
to another might occur. Sharing a datastore is supported only when the two
stores reside on the same StoreFront server or server group deployment.
