Declarative Sub-Operators for Universal Data Processing
Summary: Unified abstraction layer of declarative sub-operators (in addition to relational operators) to let users declaratively express non-relational workloads and decouple operator semantics from imperative implementations. Enables fine-grained morsel-driven parallelism and automatic optimizations in a compiling query engine, reducing implementation complexity while remaining competitive with specialized systems.
