OLTP Engines on Modern Storage Architectures
Daokun Hu, Quanqing Xu, Chuanhui Yang · 2025
Online transaction processing (OLTP) engines are crucial components of database systems, facing significant challenges due to the rapid growth of data on the Internet. Memory-oriented OLTP engines struggle with the cost and capacity limitations of hosting large data volumes, while disk-oriented engines suffer performance degradation when their working set size exceeds available memory. Limitations in DRAM density and disk latency hinder scalability and service quality, complicating large-scale data management and transaction execution.
