Abstract
Clients may subscribe to resources for the purpose of receiving notifications of changes in the resource (e.g., a file is added to a shared folder). Storing subscriptions within persistent storage provides data security in the event of a service failure, at the cost of high latency in accessing subscription data. An efficient method for tracking a resource is provided herein. A subscription service creates subscriptions and monitors resources for a client. Upon a subscribed resource change, a notification service stores a notification of the change into a queue associated with the client. Efficient resource tracking is achieved because notification and subscription data is stored in low latency soft memory. The notification service is configured to detect a failure in the notification service and/or subscription service. In the event a service fails, the client provides a recovery mechanism by resubscribing to resources with which the client has an interest.
