[Flask] Separate initialization for each worker in Flask+Gunicorn

[Abhijeet Rastogi]

Hi All,


My flask application views contact an API endpoint during the lifetime of
requests. Each of these API request requires a token. Due to the server
side limitation, I can't have two threads using the same token for
initiating requests.

Requirements:-

   - To contact this API, I need to fetch an API token. I would like to do
   this once per worker and then share that value among views. (just a
   read-only variable).
   - I want each "worker" that serves requests to have a separate "token".
   How can that be achieved in Flask?
   - I don't want to issue a fresh token each time a request is served as
   that'll be horribly slow.

How do I make that possible in Flask? Any help is appreciated.

Thanks!
