What Is Apache Parquet?
Apache Parquet is a free and open-source column-oriented data storage format. It provides efficient data compression and encoding schemes, making it ideal for big data processing. Parquet files store both the data and the metadata (schema, compression, encoding) in a single file, enabling self-describing data exchange.
How to Use
- Upload a .parquet file — Click the upload area or drag and drop a file.
- Review the metadata — The tool parses the file footer and displays schema, row groups, compression, and metadata.
- All processing is local — Your file never leaves your browser.
