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
).
