Within this directory, you may create any number of configuration files that instruct supervisor how your processes should be monitored. When using the queue:listen command, you don't have to manually restart the worker when you want to reload your updated code or reset the application state; however, this command is significantly less efficient than the queue:work command: To assign multiple workers to a queue and process jobs concurrently, you should simply start multiple queue:work processes.
