The PGM-index: a fully-dynamic compressed learned index with provable worst-case bounds

P Ferragina, G Vinciguerra - Proceedings of the VLDB Endowment, 2020 - dl.acm.org
We present the first learned index that supports predecessor, range queries and updates
within provably efficient time and space bounds in the worst case. In the (static) context of …

Recipe: Converting concurrent dram indexes to persistent-memory indexes

SK Lee, J Mohan, S Kashyap, T Kim… - Proceedings of the 27th …, 2019 - dl.acm.org
We present Recipe, a principled approach for converting concurrent DRAM indexes into
crash-consistent indexes for persistent memory (PM). The main insight behind Recipe is that …

PACTree: A high performance persistent range index using PAC guidelines

WH Kim, RM Krishnan, X Fu, S Kashyap… - Proceedings of the ACM …, 2021 - dl.acm.org
Non-Volatile Memory (NVM), which provides relatively fast and byte-addressable
persistence, is now commercially available. However, we cannot equate a real NVM with a …

LeanStore: In-memory data management beyond main memory

V Leis, M Haubenschild, A Kemper… - 2018 IEEE 34th …, 2018 - ieeexplore.ieee.org
Disk-based database systems use buffer managers in order to transparently manage data

HOT: A height optimized trie index for main-memory database systems

R Binna, E Zangerle, M Pichl, G Specht… - Proceedings of the 2018 …, 2018 - dl.acm.org
We present the Height Optimized Trie (HOT), a fast and space-efficient in-memory index
structure. The core algorithmic idea of HOT is to dynamically vary the number of bits …

RM Krishnan, J Kim, A Mathew, X Fu… - Proceedings of the …, 2020 - dl.acm.org
Non-volatile main memory (NVMM) technologies promise byte addressability and near-
DRAM access that allows developers to build persistent applications with common load and …

Livia: Data-centric computing throughout the memory hierarchy

E Lockerman, A Feldmann, M Bakhshalipour… - Proceedings of the …, 2020 - dl.acm.org
In order to scale, future systems will need to dramatically reduce data movement. Data
movement is expensive in current designs because (i) traditional memory hierarchies force …
