Building a Zero-Allocation HTTP/1.1 Parser with OxCaml for High-Performance Research Infrastructure
By

Pulled from the oven just right. Trustworthy, fact-dense, deeply satisfying.
Summary
The article details the development of 'httpz', a high-performance HTTP/1.1 parser built using OxCaml that achieves zero heap allocation. The author explains their motivation for using OxCaml over other languages like Rust or Python, highlighting OxCaml's performance advantages through language extensions like unboxed types, local allocations, and mutable local variables while maintaining OCaml's functional programming style. The focus is on building efficient research infrastructure for planetary computing to handle petabytes of TESSERA embeddings.
Key quotes
· 4 pulledOxCaml has a number of language extensions that give giant leaps in performance for systems-oriented programs, while retaining the familiar OCaml functional style of programming.
And unlike Rust, there's a garbage collector available for 'normal' code.
I am also deeply sick and tired of maintaining large Python scripts recently.
