Petquar: a browser tool that lays bare any Parquet file's internals
Vu Trinh vibe-coded Petquar, a browser tool that parses Parquet files with Rust arrow-rs and visualizes internals normally hidden: row groups, column chunks, pages, schemas, encodings, Bloom filters, and min/max stats. Row and chunk sizes render proportionally to their compressed on-disk size. A practical way to finally see what the format driving most analytics workloads actually contains.
