Engage Prometheus in Rust Ecosystem
summary
Rust libraries provide a native PromQL parser (reusing the Prometheus YAK grammar) and implementations of Prometheus remote protocols, used by hundreds of projects with over 180k downloads. Two concrete approaches show capability: a YAK-based parser with C/Python/Lua bindings, and a full query engine rebuilt on Apache Arrow/Parquet/DataFusion that remaps PromQL to SQL-like plans, claims 100% compliance with vanilla PromQL on compliance tests and adds query optimization, distributed execution and strict typing.
