cayley init with gaedatastore backend throwing error

[elizabet...@nytimes.com]

Hello,
I'm trying to run cayley on a GCE instance and using Cloud Datastore backend. However, this is the error I'm getting

cayley init --db=gaedatastore
E1014 16:06:18.433969 3715 cayley.go:301] ignoring unproductive database initialization request: database type is not persistent

However, I checked here, and apparently the QuadStore persistence is set to true: https://github.com/cayleygraph/cayley/blob/943126815d008a39f2dca594cc8194a34898de9a/graph/gaedatastore/quadstore.go#L89

Not really understand what's going on. Do you have config examples for running this configuration? What else need to be provided? Or does this only run on GAE instances.

Thanks,
Elizabeth.
