Pipelining is cool, though this could've easily just been a library with nice chaining and combinators in your language of choice (seems to be Go here).
Yeah, but isn't the nice thing here that you can run it directly in your database? Which has all the data and probably a fair bit more compute power than your laptop/PC.
Edit: my comment acted like ORM type libraries than execute within databases like Ibis don't exist. My bad!
