The Relationship Between Databases and Emerging Hardware Technologies

Database and New Hardware Technology Relationship

In the past decade, new hardware products have significantly influenced database system design, with major advances including multi‑processor (SMP), multi‑core, large memory, and SSD technologies.

Impact of New Hardware on Database Design

Multi‑processor and multi‑core architectures have driven databases to fully exploit parallel processing capabilities, shifting focus from single‑processor designs to high‑concurrency parallelism. SSDs provide high IOPS and low latency, prompting new storage engine designs that leverage SSD I/O while mitigating wear‑out issues. Large memory has led to in‑memory engines and memory‑optimized versions of products such as SQL Server.

Research on NVM (non‑volatile memory) has produced new engine prototypes, while GPUs and FPGAs are used mainly to accelerate specific OLAP operations like scans, joins, and aggregations.

Stages of New Hardware Introduction

Pure Academic Research Stage: Universities and corporate research labs design new storage engines from scratch to explore possibilities, publishing papers and patents.

Engineering Research Stage: Companies adapt existing products with partial modifications, producing engineering papers and sometimes spawning startups.

Productization Stage: Engineering teams integrate mature technologies into commercial products, with some open‑source adoption.

Database Products Related to New Hardware

Traditional engines (Oracle, SQL Server) have largely adopted SSDs by direct replacement rather than redesign. In‑memory databases (e.g., MemSQL, SAP HANA) emerged with large memory. GPU‑based startups include Kinetica, SQream, ParStream, PG‑Strom, MapD. FPGA‑based solutions such as Netezza and KickFire have seen limited commercial success, though major cloud providers explore FPGA acceleration.

NVM products like Intel Optane (DCPMM) are being integrated into solutions from Oracle, SAP HANA, and SQL Server, with academic contributions from institutions like CMU.
