Udon: Efficient Debugging of User-Defined Functions in Big Data Systems with Line-by-Line Control
Summary: Udon enables line-by-line debugging of UDFs in big data systems, with breakpoints, inspections, and live edits on a single tuple. A debug-aware execution model, cross-UDF state transfer, and optimizations keep overhead low while scaling across diverse UDF workloads. (summarized by gpt-5-nano on Feb 09 2026)
