X-Engine: An Optimized Storage Engine for Large-scale E-commerce Transaction Processing
Summary: X-Engine: a write-optimized storage engine for large-scale OLTP in POLARDB, tackling promo-driven bursts and hot-record skew. Key ideas: tiered storage with LSM-tree, FPGA-accelerated compactions, asynchronous writes, and incremental cache replacement. (summarized by gpt-5-nano on Feb 09 2026)
