IMLane: Composable Framework for Efficient AI Function Execution in Database Engine
Summary: IMLane accelerates in-database AI functions by replacing CPython-limited thread parallelism with low-overhead process execution and decoupling scheduling from the engine. Integrated into OceanBase/DuckDB, it delivers 7.48×/5.04× average speedups. (summarized by gpt-5.6-luna on Aug 28 2026)
