DTtree: A Novel Read/Write-Optimized Learned Index for Database Systems

This paper proposes a novel learned index called DTtree that can optimize both read and write performance. DTtree adopts two novel designs. (1) To improve write performance, DTtree uses a dynamic filling rate and overflow buffers for each leaf node. The filling rate of a leaf node is dynamically det...
