Simple Windows desktop application for viewing & querying Apache Parquet files.

Main UI

Please also checkout the Wiki for a detailed user guide: https://github.com/mukunku/ParquetViewer/wiki

Summary

This is a quick and dirty utility that I created to easily view Apache Parquet files on Windows desktop machines.

If you'd like to add any new features feel free to send a pull request.

Some Key Features:

  • Run simple sql-like queries on chunks of the file
  • Generate ansi sql schema for opened files

Limitations

This application can only open Parquet files located on the Windows machine the app is running on. It cannot connect to HDFS to read parquet data.

Complex types such as structs, arrays and maps are not supported at this time.
