About Parquet & DuckDB
Apache Parquet is an open source, column-oriented data file format designed for efficient data storage and retrieval. It provides efficient data compression and encoding schemes with enhanced performance to handle complex data in bulk.
Client-Side OLAP Analytics
Typically, analyzing Parquet files requires setting up Python, Pandas, or PySpark environments, or uploading your massive datasets to cloud data warehouses. This tool allows you to explore Parquet files completely in your browser. Using DuckDB-WASM, an in-process SQL OLAP database management system compiled to WebAssembly, you can run blazing fast analytic queries directly against local files using your computer's own memory and CPU.
