"""
This is an example demonstrating how to run a scheduler to process schedules added by
another scheduler elsewhere. Prior to starting this script, you need to run the script
(either async_scheduler.py or sync_scheduler.py) that adds or updates a schedule to the
data store. This script will then pick up that schedule and start spawning jobs that
will print a line on the console on one-second intervals.
This script requires the "postgresql" service to be running.
To install prerequisites: pip install sqlalchemy asyncpg
To run: python sync_worker.py
