Connecting to AppEngine Datastore in Local Development via Cloud Datastore API

In a mixed AppEngine/GCE environment, extending Cloud Datastore access to the GCE side can be beneficial. However, connecting to the AppEngine embedded datastore during local development presents certain challenges.

Limitations in Development Environment

Currently, this connection is not possible in the local development environment due to the following reasons:

• The Google Cloud Datastore tool (gcd.sh) uses the Java development server, while AppEngine development for Go utilizes the Python development server.
• The underlying storage differs between these server types, making direct communication incompatible.

Workarounds

Use of Protocol Version API

It is possible to use the protocol version of the Cloud Datastore API directly with Go. This involves crafting HTTP requests manually and using the protobuf definition compiled to Go code. While it does not share data between the application and development datastore, it offers a viable workaround.

Consideration:

When exploring these options, it is essential to remember that the development server does not support the JSON API used by the Go library. The protocol version API provides a more stable and direct alternative for local testing purposes.
