schedule an API call inside unix/python environment

Question

I want to implement the schedule tweet feature as similar to hootsuite or buffer.

The way I have designed my current architecture is - a cron job runs every minute, which evokes a shell script, which fires a python/django command to see if there is any scheduled tweet in the database for current time. If yes, make an API call to twitter.

Is there a better way of doing it?

Answer 1

可以使用django-celery安排相同的过程

Answer 2

It's hard to define what's "better" way of doing it since it depends on implementation/problem.

For simple implementations I would go the same route you went, that is cron. If that's OK with you, ie there are no other problems you want to avoid I would advise sticking with it.

If you have need for something else you can for example:

• Start long running process/daemon which will track time and run/spawn actions on timer events
• Start long running process + task queue so that queue will send data to process when it should be run (Proposed by @Siva django-celery is such solution)
• Do a super-simple cron-independent solution which runs the tasks then sleeps for set amount of seconds (30s).
