I started writing and never completed a dead simple ETL framework that left most of the work up to the programmer. It was basically just an http server that you could hit with cron jobs, a DAG data structure for mapping the process, and some annotations that you could use to specify that a node/program step was concurrency safe, blocking, etc. You’re entirely right that there’s way more to ETL than meets the eye, but this still makes me want to dig it back up.
