KEN: An Execution Engine for Unstructured Database Systems

Summary: KEN: execution engine for UDBMSs that makes model cascades practical by dynamically adapting cascade use to workload and optimizing GPU placement/scheduling. Key novelty: exposes middle-ground accuracy/latency tradeoffs for unstructured operators, avoiding the usual small-vs-LMM binary. (summarized by gpt-5.4-mini on Apr 12 2026)
