Inspect Parquet file metadata with the iParq CLI, including compression, encodings, physical and logical types, row groups, sort order, statistics, geospatial statistics, dictionary pages, page indexes, page locations, Bloom filters, and storage sizes. Use when an agent needs to explain how one or more .parquet files were written, compare their storage-level features, diagnose missing Parquet optimizations, or obtain machine-readable Parquet metadata without reading the row data.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# iParq Parquet Inspector Inspect Parquet storage metadata without querying the file's row data. Prefer JSON output so results remain machine-readable and diagnostics stay separate on stderr. ## Run an inspection Use the published package without installing it permanently: ```sh uvx --refresh iparq inspect FILE.parquet --format json --details --sizes ``` If `iparq` is already installed, run it directly: ```sh iparq inspect FILE.parquet --format json --details --sizes ``` Pass multiple paths or shell-expanded glob patterns to compare files. iParq emits one JSON object for a single file and an array with a `file` field for multiple files. ## Select the minimum useful detail - Use `--metadata-only` for creator, row count, row groups, Parquet version, and serialized metadata size. - Use `--column NAME` to restrict column-level output. - Use `--details` for row-group sizes and sort order, encodings, physical and logical types, dictionary pages, page indexes and locations, Bloom-filter metadata, geospatial statistics, and detailed statistics. - Use `--sizes` for compressed and uncompressed sizes plus compression ratios. …

How to install
mdr add miguelelgallo/iparq/iparq-parquet-inspector@sha256:9a24ab43b1a26f32The line at the top of this page pins the label git:20260906.4871336, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
