Azure function even function is in use still experiencing cold start

[SainiAshish]

We have a azure function which we are keeping warm using a time trigger function every 1 min. But still we are experiencing cold start. Static members are re-initializing after some time.

Doesn't a time trigger function keeps the whole function app warm?
Or do we have to keep pinging all the all the functions within function to keep them warm.

Your app will periodically be moved between workers in the consumption plan, and will experience cold start. We have a SKU planned to address this issue, but for the time being the only real mitigation is to run in an app service plan
