Hello here, After trying mprocs for "start-airflow" I think mprocs would be a great candidate to use for standalone airflow. I think currently one of the problematic things for standalone airflow is the log multiplexing at the output and lack of control over the individual processes run as part of "standalone" airflow execution.
I think `mprocs` solves many of those problems that we have with "airflow standalone" nicely. It provides a very nice, terminal interface to monitor and control multiple processes - very user friendly, supporting all modern terminals, copy&pasting, mouse control for monitoring of running processes, ability to restart individual processes and it has also a number of interesting features in the roadmap. But even today it offers a lot more than we have today in standalone airflow: * separate logs for each process with nice navigation * easy copy&paste * keyboard shortcuts and navigation to switch and move between panels * ability to individually restart processes when needed * ability to autorestart processes when they fail * ability to run scripts defined in package.json (it's an npm tool) I'd say it sounds like a good idea to have it as part of standalone airflow. One drawback it has that it has a dependency on npm, but also it has a standalone binary, that Airflow Standalone **could** download from https://github.com/pvolok/mprocs/releases and run internally. Or maybe search for or even implement simple version of it as alternative in Python. We could have an `--mprocs/-no-mprocs` flag when starting the standalone airflow (and decide on default setting, also we could give the user a choice to run mprocs by default when they run standalone and download the binary, I think in general it delivers a very good and very user-friendly (and not even expert-friendly like tmux) interface and "airflow standalone" would get an immediate usability boost with it. I think the TUI interfaces of those sort have shown it's power over last years (k9s being the flagship tool). I would love to hear your thoughts about it. J.
