Right now, you declare periodic tasks with the @manager.periodic_task decorator.. It accepts a # of ticks to specify interval to run.
The issue I have is that changing FLAGS.periodic_interval will modify every periodic task. It's also slightly annoying to have to compute # of seconds you'd like to run a task at... based on dividing it by the setting of periodic_interval to get # of ticks.
Rough ideas of what I'd like to do for Folsom:
change @manager.perodic_task() to allow keyword args of "enabled" and "interval". interval is in seconds. "ticks" goes away.
Modify the task runner to be a bit more smart. Since it has a list of periodic tasks to run (and it can ignore ones that are enabled=False).. it can figure out the amount of time it needs to sleep to run the next task. Essentially the task runner can sit in a greenthread sleeping until the next periodic task should run based on its "interval" setting.
Something like that :) Other ideas welcomed!
Another example: If you want a periodic task to run at 5 seconds, but poll_interval is 60s.. you can't do that right now without modifying poll_interval down to 5s. Then you would need to go up the 'ticks' for every other task by 12x.
