I don't have any experience with this, but I'm pretty sure you can pass an optional RPC object argument that can specify a callback, to both the URL fetcher and the datastore, to make them act asynchronously. That way, you should be able to run operations simultaneously.

Yup, we're using Python. I've actually found the cloud to be slower than the local SDK. Maybe there have been improvements in the SDK, but the roundtrip time on the synchronous RPCs in the cloud adds up.

Making datastore tasks asynchronous and non-blocking is very attractive. I'll have to read up on RPCs. Thanks for the pointer!
