[Migrated] Keep Warm should Default to 15 Minute Intervals #344

Based on reading this article, it looks like we only need the keep_warm event once every 15 minutes.

Related #851

Is there any validity to this... it would be beneficial cost wise. I think the default now is 4 mins. Can we extend it and still get a keep-warm effect?

Hi @monkut we can increase the keep_warm time interval to 15 mins. I found some answers (links below) mainly AWS keeps lambdas warm from 5-45 mins (some say it's 5-15 mins and as per others it's 30-45 mins). So, if we keep the lambdas warm callback function to 15 mins, we would save around 2/3 of the cost of maintaining the lambdas warm.

Basically, it costs around $7-$10 to keep the lambdas warm with a 4 mins callback if we make the default callback time to 15 mins we would be saving more than 2/3 of the costs.

I have applications that are dependent on the function being 'warm'.

We need to do some testing (across regions?) to confirm response times with/without keep warm at various times.

Hi @monkut I will perform the tests across regions and will submit the results here.

monkut commented 1 year ago

I have questions about how effective the keep_warm function is, however, this issue is only about changing the existing keep_warm value from the current 4 minutes to a more appropriate value.

If tests show that we can increase the keep_warm value and maintain it's current effectiveness (compareable to 4 minutes) then we should have a PR update the value.
