TQEx: Tensor-based Query Engine Enhanced by Bridging the Gap

Summary: Analyzes the gap between irregular SQL and uniform tensor runtimes; derives guidelines (var-length storage, tensorized joins/aggregates, multi-XPU mapping) to bridge it. Implements TQEx—tensor-based engine with tailored storage/operators—up to 41.9× vs TQP and ~12–28× vs DuckDB/HeavyDB on TPC-H. (summarized by gpt-5-mini on Feb 11 2026)
