Re: [google-appengine] Can I run an AppEngine app with mixed Java and Go runtimes?

[Diego Duclos]

Wouldn't having a module in java and the other in go be a much better
option then hacking this with versions ? This really isn't the intended
usage of versions

Re: [google-appengine] Modules vs Multiple Scripts?

[Diego Duclos]

Also important: each module is allowed to scale up / down seperatly, which
means you can configure the more important things to scale faster while
allowing slower scaling (and thus lower costs) on less important modules

[google-appengine] Why are cloud endpoints so slow ?

[Diego Duclos]

I've done some (non extensive) tests on google appengine,
and my response times vary from anywhere between 100ms and 5000ms when
directly sending http requests to a cloud endpoints.

Regardless of the actual response time, the google cloud console always
shows a processing time of around 50ms, which, while also somewhat
long-ish, is much more reasonable.

For the 100ms requests, I can safely know that the other 50ms are just
regular latency, but I have no idea where the cloud endpoint could be
spending 4.5 seconds at, and the logs show nothing useful at all.

Does anyone have some guidance for me regarding to this ? 5 seconds is
unacceptable slow and makes them completely unusable.

Re: [google-appengine] Re: Why are cloud endpoints so slow ?

These are not loading requests unfortunatly, The first request was ignored
here, that one usually takes around 10 seconds (That's with Go, funnily
enough)

[google-appengine] OpenID Connect support

[Diego Duclos]

With registrations for using the old OpenID 2.0 endpoints now closed, and
the appengine users API not supporting openID connect at all,
Would it be possible to get a timeline for openID connect support in the
users API (In my case, with Go, but I assume this is largely language
agnostic)
