[google-appengine] Re: Migrating from Go on GAE to Go on GAE using Google App Engine Go library...

[Adam Jack]

For completeness, as I wandered in the wilderness confused I stumbled upon 
this:

  
 
https://cloud.google.com/appengine/docs/standard/go/go-differences#migrating-appengine-sdk

... and I believe the answer to my question is *don't* do what I was 
attempting, instead skip the Google App Engine SDK (as a thing of the past) 
and go to Google Cloud APIs.

regards

Adam

Thanks for reaching out!

It seems as though you have resolved your question, and that’s great! The 
fact that you came back and posted your solution is great. This will allow 
others who face the same issue to be able to resolve their issue.

Regarding your query about Memcache, it is not deprecated, but simply just not 
available for the App Engine Flex environment 
. 
For a list of all deprecations, please consult this document 
.
