How to share App Engine SDK's local Datastore with google-cloud app?

[MeLight]

Hi,
I'm building an app which should share the Datastore with an App Engine app. I want to test this locally, so I've read in the troubleshooting guide that I have to use gcd.sh and point it to a directory with a pre-created Datastore project.

Is there a way to serve the App Engine SDK's Datastore from this folder? Or do I need to setup some sort of intricate process in order to copy the contents of the App Engine SDK Datastore to the one server from the special folder?

I'm on Windows 10 for dev, and GCE Linux for deployment.

Currently it's not possible to share local backends between the Cloud Datastore emulator and the App Engine specific emulator.

@stephenplusplus can you move this issue over to google-cloud-datastore?

[MeLight]

@pcostell so no way to develop it locally?

Uh oh, speaking of App Engine, looks like the GitHub issue mover is down :) https://github-issue-mover.appspot.com

Moved to googleapis/google-cloud-datastore#137

@MeLight you can indeed develop locally with the Datastore emulator and this library. We have a section in our docs about using the Datastore emulator as well: https://googlecloudplatform.github.io/google-cloud-node/#/docs/google-cloud/0.38.3/datastore

Is there any reason the backends can't be shared? I would guess that operating a full systems with all of its parts would be a more comfortable local experience if the datastore could be shared between devappserver and other programs.

Heads up! If your GAE app uses python27 standard runtime, running locally, it can use the cloud datastore emulator now!
