Accelerating Python UDFs in Vectorized Query Execution
Summary: Accelerates embedded Python UDFs in vectorized analytical engines by combining vectorization, compilation (JIT/AOT), dynamic loading, and parallel execution to enable transparent in-process execution. Compares compilation frameworks and shows that compilation+parallelism yields large speedups and scalability. (summarized by gpt-5-mini on Feb 09 2026)
