HaSiS: A Hardware-assisted Single-index Store for Hybrid Transactional and Analytical...
summary
A B+-tree single-index store leverages commercially available computational storage drives with transparent compression to run HTAP without dual indexes. The prototype implements a hybrid buffer pool, a per-page logs design and hybrid page format, and runs on ScaleFlux-like CSD hardware. Evaluation on production CSDs shows OLTP and OLAP throughput comparable to MySQL/Postgres and column-store baselines while delivering near-instant OLAP freshness and lower cross-index migration overhead.
