PHP ETL Adapter: Parquet

An opinionated config-driven Rust server that publishes Parquet and Delta datasets as fast, typed HTTP APIs from local disk or object storage, with interchangeable DuckDB or Arrow+DataFusion backends, JSON and Arrow IPC output, and production-ready features like auth, metrics, and hot reloads.

An embedded analytical database written in Rust, compatible with DuckDB. Its own columnar format with global dictionaries and multi-column compression, and operators that run directly on the encoded data. The bar is 10x DuckDB on ClickBench at a tenth of the disk.

Token-efficient data serialization for LLM/AI. 50% fewer tokens than JSON, 93% better value/token. Rust, schema validation, LSP.

Data Engineering infrastructure that controls inbound tabular data file feeds and validates data contracts
