Performance Optimization of TXRocks Sum Operation: Pushdown, Record Conversion, and Multithreaded Concurrency

This article analyzes the high space efficiency but poor sum performance of TXRocks compared to InnoDB, identifies three main bottlenecks, and details three optimizations—sum push‑down, selective record conversion, and multithreaded execution—that together reduce query latency to less than 5% of InnoDB’s original time.
