Passing DBs through continuations

The author describes a shortcut to improve database performance using a technique called continuation-passing style (CPS), which allows operators to compose into tightly fused operations automatically. This approach is used in the Prela database, which maps cleanly to both a logical Entity/Relationship data model and a columnar physical storage, and achieves fast columnar execution when compiled.
