Hello Alexey, You are correct that Pub/Sub is not a complete replacement to the Channel API, and was recommended as a simple lightweight callback communication alternative. The intended replacement is indeed Firebase. As you mentioned, Pub/Sub is designed for pre-defined Topic/Subscriptions,

Hey Vidya. You are correct that the instance start time is greatly based on your code, as each time a new instance is created it must load and prepare a fresh copy of your code to serve. As for the reason why you are seeing a single instance handling the bulk of your requests, this comes down

Re: [google-appengine] Re: Why resident instances in auto scaling are idle?

You are correct, executing a URL Fetch request during the initiation of your code will cause a large amount of latency as your instance must wait for the requesting server to respond. As previously mentioned you can use the Stackdriver Trace tool on a specific

[google-appengine] Re: Why resident instances in auto scaling are idle?

Resident Instances turning into Dynamic Instances to handle requests does not effect the time required to start an instance (it is actually designed to help it). When a new Idle Resident Instance is required, an '/_ah/warmup' will be sent to your application. This will trigger the creation of a

[google-appengine] Re: Why resident instances in auto scaling are idle?

Idle Resident Instances are instances waiting with your application code pre-loaded and warmed up, but never actually accept requests. When an Idle Resident instance is needed by your application due to high traffic or CPU intensive operations, your Resident instance will turn into a Dynamic in

Hi Taengoo, The Task Queue executes tasks the same way as a normal client would when attempting to access your App Engine service; by sending an HTTP GET request to your service's URL endpoint. Task Queues are therefore affected by the same conditions as any normal request to your app would, su
