User-Defined Table Operators: Enhancing Extensibility for ORDBMS
Summary: Proposes user-defined table operators (UDTO) to support arbitrary N-ary operators inside SQL, beyond standard UDFs. Demonstrates scalable, parallel execution and orders-of-magnitude gains for complex UDFs, aligning with commercial ORDBMS architectures.
