A SQL-like query language built on algebraic principles, emphasizing compositionality and control, with a core engine under 1k lines of Rust code. Positioned as a demonstration of language-agnostic relation combinators.
Prela addresses the demand for more flexible and performant data querying. The shift to a SQL-like syntax from a unicode-based one directly responds to user feedback, indicating a pragmatic approach to adoption. The rewrite from Julia to Rust for performance and code simplicity aligns with industry trends favoring systems languages for foundational infrastructure. Prela's long-term vision, as a demonstration of relation combinators rather than a standalone language, targets developers seeking deeper control and embeddable data manipulation paradigms. This approach could influence future data processing frameworks by offering a lean, high-performance alternative to traditional query engines, abstracting complex logic into reusable components. The focus on a minimal engine (under 1k lines) appeals to those prioritizing efficiency and foundational control.
I'm excited to share "take 2" of the Prela query language.After sharing the previous version here, I've received some valuable feedback, the main one being the weird unicode-based syntax throwing people off.Prela now has a more familiar SQL-like syntax while adhering to the algebraic principle, which makes the language compositional and controllable, all the while keeping the core engine under 1k lines of code.The engine has also been rewritten from Julia to Rust, resulting in both simpler code and faster performance (not just because "Rust fast Julia slow", but for some pretty deep compiler-level reasons that I'll hopefully write about at some point).In the long run, I think the value of Prela is not as a single query language, but as a demonstration of the power of relation combinators which can be implemented in any language, just like iterators.
