Apache Parquet for .NET
Fully managed, safe, extremely fast .NET library to 📖read and ✍️write Apache Parquet files designed for .NET world (not a wrapper). Targets .NET 8, .NET 7, .NET 6.0, .NET Core 3.1, .NET Standard 2.1 and .NET Standard 2.0.
Whether you want to build apps for Linux, MacOS, Windows, iOS, Android, Tizen, Xbox, PS4, Raspberry Pi, Samsung TVs or much more, Parquet.Net has you covered.
Features at a glance
- 0️⃣ Has zero dependencies - pure library that just works anywhere .NET works i.e. desktops, servers, phones, watches and so on.
- 🚀Really fast. Faster than Python and Java, and alternative C# implementations out there. It's often even faster than native C++ implementations.
- 🏠NET native. Designed to utilise .NET and made for .NET developers, not the other way around.
- ❤️🩹Not a "wrapper" that forces you to fit in. It's the other way around - forces parquet to fit into .NET.
- 🦄Unique Features:
- The only library that supports dynamic schemas.
- Supports all parquet types, encodings and compressions.
- Fully supports C# class serialization, for all simple and complex Parquet types.
- Provides low-level, high-level, and untyped API.
- Access to file and column metadata.
- Integration with DataFrames (
Microsoft.Data.Analysis).

UI
This repository now includes an implementation of parquet desktop viewer application called Floor (parquet floor, get it?). It's cross-platform, self-contained executable made with Avalonia, and is compiled for Linux, Windows and MacOS.
Floor is not meant to be the best parquet viewer on the planet, but just a reference implementation. There are probably better, more feature-rich applications out there.
Installing
Download it from the releases section. On Windows, you can install it with winget - winget install aloneguid.ParquetDotnet.floor.
