Parkhay is an interactive visualization tool for exploring the physical layout of Parquet files. It presents information at the thrift specification level, making it ideal for those who need a detailed understanding of the internal file structure. Raw byte-level data can be previewed on demand for non-metadata sections, eg. Column Chunk pages and Bloom filter bitsets.
To run:
cargo run -- <path/to/file.parquet>
- Support object storage reads via OpenDAL
- Warn when there are regions of the file that are not referenced from the metadata, eg. arbitrary embedded binary content
- Enable export of raw page bytes to a file on-demand
- Display user-defined indexes referenced within KeyValue metadata
- Files with geospatial types, eg. those in here are not supported
- Encrypted files are not supported
