PRQL: a simple, powerful, pipelined SQL replacement
At my previous employer, data scientists would regularly spend entire days only running 3-4 Hive queries and waiting hours for the results to come back... job failed. PRQL looks much easier to use, and the goals of good auto-complete and type-checking will make it even better. If any corporation with lots of data scientists would like to fund work on an open-source project, this seems like a no-brainer.
