Python 3 is now available on App Engine standard environment

Is GRPC supported? My gut feelign is no, but I hope I am wrong

Edit: Holy shit this is so bittersweet. I was relying heavily on the batteries included user management, logging, admin only handlers, and especially the super easy cron job definitions.

IDK what to think about this. It kinda takes away all the things that made App Engine worth it for me as a programmer who doesnt want to do dev ops.

AFAIK you can't run a gRPC server on App Engine, but you can access other gRPC services (like all the GCP APIs) as a client. I might be wrong about the server part.

All those things you mentioned in the edit should be supported in the new runtime.

Edit: I see what you mean. The deeply integrated services are removed in favor of more portable solutions, like Logging moving to Stackdriver Logging (though stdout is still logged automatically), Users moving to Firebase Auth, etc. Cron should still work fine though.

(I work for GCP)

Thanks for the reply. Yeah I'm bummed about that because id rather use GRPC client libraries for my apps than the endpoints discovery doc generated ones.

Also according to this they are not supported directly anymore except logging might still work but the wording is unclear. https://cloud.google.com/appengine/docs/standard/python3/pyt... .

That page mentions that it supports the google-cloud-python libraries, which are the primary GCP gRPC client libraries for Python. The Apiary service-discovery library you are referring to is called google-api. The new GAE version doesn't support the old GAE-only libraries, like memcache, datastore, etc. These older services only worked with GAE, and therefore weren't portable to other services, which they are in the process of replacing. If I recall, the old version didn't support the google-cloud-python libraries either, so it's good to see that they are moving in that direction. I could be wrong about that though.

In short, it looks like you have access to the main GCP gRPC libraries. You don't have access to the GAE-only service libraries.

Disclaimer: was former GCP customer support.

The Google Cloud client libraries [1] are fully supported. You can use these to access services like Datastore, Spanner, Natural Language, and many other Cloud services. They work on this new runtime, on the flexible environment, on a VM, your local machine, etc. In my opinion, this is the most Pythonic way to integrate Cloud services in your app while maintaining portability.

[1] https://github.com/GoogleCloudPlatform/google-cloud-python -- small caveat, the repo currently states that they're not supported on App Engine standard environment. That will be updated soon to clarify that the Python 3.7 runtime on the standard environment is supported.
