I have two flask restful API's. Both are working fine. API1 is only for reading the database, API2 deals with update/insert. Both access the same database.
Problem:
API1 stops working every morning and I have to restart it everytime (once in the morning). Error is - MySQL server is gone away.
API2 always work doesn't give any error.
Earlier, I thought wait_timeout (default 8 hours) could be the reason that API1 throws that error. But, why does API2 work then? (I use a class for database operations, and I have connect string in its init method. Also, I do not close any of the database connection. I'll very soon edit to corect it, just giving the info here to know the exact reason for that error)
Question - Why does only API1 gives that error while API2 never?
PS - I asked this on stackoverflow but was advised to post this here, since I never found an answer reposting here
