A software development kit (SDK) is disclosed that can reduce unnecessarily polling of a network service. The SDK is modified to cache response objects received from a network service that describe the state of a computing resource. Polling requests received for the state of the computing resource are satisfied from the cache when possible, thereby avoiding the polling of the network service. Entries in the cache can be invalidated based upon events generated by the network service that indicate that the state of the computing resource has changed.
