Parq is a tool for Windows that allows the inspection of Parquet files. There are precious few tools that fit this category, and so when we were investing into parquet-dotnet we thought we'd build a console application that at least begins to address the deficit.
There are three distinct output formats that the parq tool supports:
The Interactive mode transforms the console into a navigation tool over the parquet file you supply. You can use the arrow keys to move around the dataset and look at summarised data.
The Full mode outputs the whole summarised dataset to the console window, with columns truncated at a configurable size but designed to allow tooling interoperability with a formatted output.
The Schema mode outputs the list of columns, which is useful if you're a developer looking to wrap Parquet data sets into strongly typed models.
