Icon

Fully managed, safe, extremely fast .NET library to ๐Ÿ“–read and โœ๏ธwrite Apache Parquet files designed for .NET world (not a wrapper). Targets only modern .NET runtimes such as .NET 10 and .NET 8.

This project does not use LLMs for writing code. It will not accept LLMs for issues. No pull requests written by LLMs will be accepted. No LLMs for comments anywhere. Attempts to circumvent this may prevent your future contributions to this repository.

Features at a glance

  • 0๏ธโƒฃ Has zero dependencies - pure library that just works anywhere .NET works i.e. desktops, servers, phones, watches and so on.
  • ๐Ÿš€Really fast. Faster than Python and Java, and alternative C# implementations out there. It's even faster than native C++ implementations. Hardware acceleration is added in more and more places.
  • ๐Ÿ NET native. Designed to utilise .NET and made for .NET developers, not the other way around.
  • โค๏ธโ€๐ŸฉนNot a "wrapper" that forces you to fit in. It's the other way around โ€” forces Parquet to fit into .NET.
  • ๐Ÿฆ„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.
    • Fine-tune encodings per column.
    • Integration with DataFrames (Microsoft.Data.Analysis).
