PGM Index

Manticore Search 5
Manticore Columnar Library uses Piecewise Geometric Model index, which exploits a learned mapping between the indexed keys and their location in memory. The succinctness of this mapping, coupled with a peculiar recursive construction algorithm, makes the PGM-index a data structure that dominates traditional indexes by orders of magnitude in space while still offering the best query and update time performance.

PGM Indexes: Learned indexes that match B-tree performance with 83x less space
Yep, I'm working on a multidimensional version that I hope to upload to the main repo (https://github.com/gvinciguerra/PGM-index) in a few weeks.
