[korenron]

Hello,
I have a REST APi that take a picture , analyze it - and return an answer to the user.
the all process it taking ~ 25 seconds.
how can I limit , and not take another picture until the first work is done?

Hi,

pretty unusual request, as normally the opposite is what is requested.

Anyway, if you run Flask on a single-threaded, single process, not asycncronous server, the server can handle only one request at a time and will block until this request is processed and returned something.

Which server do you currently run your Flask application on?
