Embodiments of the present invention provide a system for performing caching in an image-processing system. The system starts by receiving a filtering query for resources in a cache. The system then returning a subcache in response to the filtering query. Upon receiving a resource query for resources in the subcache, the system performs the filtering query on the cache, populates the subcache with addresses of resources returned by the filtering query until the resource query is satisfied, and returns available resources from the subcache in response to the resource query.
