The pgm-index
WebbLearned index structures were first introduced in [10]. Several works on learned index structures followed [6, 7, 4, 9, 14, 13, 15, 12, 5, 11]. For example, PGM index [6], FITing tree [7], RadixS-pline [9] and ALEX [4] all investigate how to efficiently support inserts, provide better worst-case guarantees, and/or faster index construction.
