I would not rely on that. What you could do is something similar as described here: http://blog.appenginefan.com/2009/04/efficient-global-counters-revisited.html - add a second property (integer value) to your sharded model. The entity with the highest shard number is the last entity updated. - use memcache to remember the last id. Use the increment operation in memcache to increase the id whenever a new property is stored. - if the property gets evicted from memcache, find the right value from the datrastore and add it _conditionally_ back to memcache (to prevent race conditions) On Apr 26, 8:02 am, Ivan Maslov <[email protected]> wrote: > I already have it in entity.
