Alex: ML-enhanced range index, similar in functionality to a B+ Tree

Discussion from 4 days ago: https://news.ycombinator.com/item?id=23571741

This looks like a cool technology. But I must object to using "ML" to refer to every type of statistics. This is linear regression, which is about the least exotic thing I can think of.

Mmm tasty.

If anyone wants a backstory building up to this data structure checkout this talk: https://youtu.be/sPhpelUfu8Q He builds an rrb-tree which uses the same underlying concepts ALEX uses, just without the ML-enhancement.

Already discussed previously on HN
