Abstract
A storage system query mechanism and corresponding techniques for implementing queries are provided. In an exemplary method, control path data in a storage array is processed by obtaining an object model (OM) data object comprising retrieved control path data upon an initial user request; storing the OM data object in a cache using one or more façade data classes; employing a refresh service to listen to refresh events that impact a validity of the OM data object, wherein the OM data object is evicted from the cache when the validity of the OM data object is impacted by one of the refresh events; and delivering the OM data object from the cache upon a subsequent user request if the OM data object remains in the cache at a time of the subsequent user request.
