Show HN: Prela – Purely Algebraic Relation Combinators

Category: infrastructure

Tags: query-language, relational-algebra, julia

Score: 6.0/10 (Innovation: 7, Technical: 8, Documentation: 6, Utility: 3)

Prela is an embedded query language in Julia based on Tarski's Algebra of Relations, using binary relations and relation combinators to express queries in a concise, navigational style. It offers a novel algebraic approach to query composition that enables advanced features like CTEs and UDFs via host language constructs, though it remains an early-stage research prototype with limited practical adoption.

Target audience: data engineers
