Multithreading for Python Django

by

I’ve continued using this implementation at scale and in production with no issues.

Decorator definition:

def start_new_thread(function):
    def decorator(*args, **kwargs):
        t = Thread(target = function, args=args, kwargs=kwargs)
        t.daemon = True
        t.start()
    return decorator

Example usage:

@start_new_thread
def foo():
  #do stuff

Over time, the stack has updated and transitioned without fail.

Originally Python 2.4.7, Django 1.4, Gunicorn 0.17.2, now Python 3.6, Django 2.1, Waitress 1.1.

If you are using any database transactions, Django will create a new connection and this needs to be manually closed:

from django.db import connection

@postpone
def foo():
  #do stuff
  connection.close()
