User-Defined Operators: Efficiently Integrating Custom Algorithms into Modern Databases
Summary: Introduces User-Defined Operators (UDOs) to tightly integrate custom algorithms into modern database query engines. Idiomatic code in common languages is plugged directly, avoiding data export, preserving ACID guarantees, and achieving performance competitive with specialized analytics tools.
