So basically I’ve created APIs in node js & hosted that on render & database I’m using is mongodb, so in layman terms as soon as request comes on backend, data is pulled from database & response given to the client end.
So what I’ve observed is, when I open my app after ample amount of gap let’s say after 1 hour or something, when I send first request to the render it takes around 60 to 90 seconds to give response on the app, and after this first response if I send a request immediately then I quickly get the response let’s say 5 seconds. And if I send a request after 1 hour then again it’ll behave the same like taking 60-90 seconds.
What do we call to this phenomenon? Cold start/boot?
Free instance types spin down after 15 minutes of inactivity and then will restart when they next receive a request. This behavior is documented at https://render.com/docs/free.
If you need your service always be available, moving to a paid instance type avoids this behavior, and the service will remain running constantly.
To change the instance type, follow these steps:
Navigate to the service in our dashboard
Open the ‘settings’ tab
Click on the ‘Change Instance Type’ button
Select the instance type you wish to use (the minimum to avoid sleeping is Starter)
If you want to change back to the free instance type, repeat this process but select ‘free’
