parquet-metadata
A tool to show metadata about a Parquet file
Decision gist · record as of 2026-08-14
No, unless you have a specific need for this exact tool and can accept that it has not been maintained since 2018. The package works for basic Parquet inspection, but there is no active development, and compatibility with newer Parquet features or Python versions is uncertain. Consider alternatives that are actively maintained if you need reliable, long-term support.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Installation is straightforward with no runtime dependencies, but the package has been abandoned since its only release in 2018 and last commit in 2021.

What it is and what it does
Parquet-metadata is a lightweight command-line utility that extracts and displays metadata from Parquet files in a tab-separated format. It shows file-level information like creation tool and row count, then breaks down each row group with column-level details including data type, compression method, encoding, compressed and uncompressed sizes, and min/max statistics.
The tool is designed as a simple inspection utility for developers and data engineers who need to understand the structure and properties of Parquet files without loading the data itself. It has no runtime dependencies and installs quickly, making it a minimal addition to your toolkit for Parquet file analysis.
Use it for
- Inspect compression ratios and encoding choices in Parquet files to understand storage efficiency
- Verify row group structure and column statistics before processing large Parquet datasets
- Debug data pipeline issues by examining file metadata without reading the actual data
- Check column types and value ranges (min/max) to validate data quality before analysis
