You should try to generate a list of N random keys for your entity because you can fetch that with only one datastore call(and no index). Aren't google-generated numeric IDs guaranted continuous? If not you can yourself assign alphanumeric keys that are continuous (or generated by a formula that you pass on to the random generator).
