Write scheduler inside tornado

[Grigory Fateyev]

Hello!

I need to run function with an interval of 10 minutes. What is the
best way to do that?

You can use tornado.ioloop.PeriodicCallback to create a period timer.

Of course you can call IOLoop.add_timeout to create a timeout callback.Note that the timer created by IOLoop.add_timeout will run only once.

 

Maybe the code bellow will do you a favour:

 

def callback():

    print "DO SOMETHING HERE"

 

#milliseconds

interval_ms = 10 * 60 * 1000

main_loop = tornado.ioloop.IOLoop.instance()

scheduler = tornado.ioloop.PeriodicCallback(callback,interval_ms, io_loop = main_loop)
#start your period timer

scheduler.start()

#start your loop

main_loop.start()

Otavio, thank you. Can you give me a small example how to use this
method?

[Otávio Souza]

Hello there Grigory, I think Season Lee gave an smart example =)

But using the add_timeout method, as explained, call only once, the simple code is that one:

from tornado.ioloop import time

def call_me():
     print("Something")

tornado.ioloop.IOLoop.instance().add_timeout(time.time()+(10*60),call_me);
tornado.ioloop.IOLoop.instance().start();

Season, thank you very much for that complex example!

Also, thanks to Otavio and Ken.
