Open Source Projects
Most of our work is open-source. We aim to optimize database engines by leveraging the unique characteristics of storage systems
SaS C/C++ Library for SSD as SQL engine (VLDB 2021)
NV-SQL Optimize MySQL/InnoDB using leveraging NVDIMM (VLDB 2023)
FlashAlloc Novel interface for flash storage to enlighten the storage to stream write to objects (VLDB 2023)
NV-PPL Boosting Transaction Performance using Per-Page Logging on NVDIMM (SIGMOD 2025)
