Claim Text:
1. A computer-executed method comprising: maintaining a hierarchy of hash tables, each hash table of the hierarchy of hash tables storing resource identifiers for a set of child resources of a container resource, in a hierarchy of resources; wherein each hash table of the hierarchy of hash tables corresponds to a corresponding container resource in the hierarchy of resources; wherein a hierarchical position of each hash table within the hierarchy of hash tables corresponds to a hierarchical position of the corresponding container resource within the hierarchy of resources; and wherein a particular entry of a particular hash table of the hierarchy of hash tables includes a resource identifier for a particular child resource of the corresponding container resource that corresponds to the particular hash table; removing the particular entry from the particular hash table based on a characteristic of the particular child resource associated with the particular entry; and wherein the method is performed by one or more computing devices.
