9. An apparatus comprising: an interface circuit configured for receiving, from a user interface, a request for execution of at least one lambda function in an operation of a geospatial application, the geospatial application having lambda functions for operating on one or more entities of an ad hoc geospatial directory accessible by the computing device, the lambda functions having strongly typed definitions according to a prescribed symbol manipulation language that is a non-Turing complete language, that does not permit partial functions, and that is independent of any attribute of any computing system; and an execution circuit configured for optimizing execution by the apparatus of the operation on the ad hoc geospatial directory, the execution circuit configured for returning to the user interface, via the interface circuit a response to the request based on the optimizing execution of the operation, the response including a data structure including at least one of the lambda functions for a corresponding at least one of generating a query of the ad hoc geospatial directory, modifying a state of at least a first of the entities, or accessing the first of the entities; wherein the interface circuit is configured for receiving a plurality of requests for execution of respective operations of the geospatial application, the execution circuit configured for optimizing execution of the requests based on: joining the requests into at least one locally-executable request and at least one remotely-executable request, sending the remotely-executable request to a second computing device, receiving from the second computing device a remote result responsive to the remotely-executable request, executing the locally-executable request for generation of a local result, and generating the responses for the respective requests based on selective partitioning of the local result and the remote result.

The apparatus of claim 9 , wherein the remotely-executable request includes at least one of a request for a remotely-stored data structure associated with a second of the entities in the ad hoc geospatial directory, or a supply of a locally-stored data structure associated with the first of the entities in the ad hoc geospatial directory.
