License: permissive · Maintenance: active · Downloads: 1.1M/mo

## What it is and what it does

Delta Kernel Rust Sharing Wrapper is a thin Python interface to delta-kernel-rust, a Rust-based implementation of the Delta Lake protocol. It uses maturin and pyo3 to expose Rust functionality as a Python module, allowing developers to read and interact with Delta Lake tables from Python code while leveraging Rust's performance and safety guarantees.

The package is distributed as precompiled wheels for macOS (Intel and ARM), Linux, and Windows, eliminating the need to build from source in most cases. With no runtime dependencies and active maintenance, it sits between the high-level Delta Lake ecosystem and low-level Rust implementations, targeting scenarios where direct Rust kernel access from Python is needed.

Use it for:

- Reading Delta Lake tables in Python applications that require Rust-level performance or safety guarantees.
- Integrating delta-kernel-rust functionality into Python data pipelines without calling external processes.
- Testing or validating Delta Lake protocol compliance from Python test suites.
- Building Python tools that need direct access to the Rust Delta Kernel implementation.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides Python bindings to the Rust-based Delta Kernel for reading and processing Delta Lake tables through a thin wrapper built with maturin and pyo3.

Yes, if you need Python access to the Rust Delta Kernel and your platform matches one of the provided wheels (macOS 10.12+, Linux glibc 2.28+, or Windows x64). The permissive Apache-2.0 license, active maintenance, and zero runtime dependencies make it a low-friction choice. Verify that the package's API meets your use case, as the documentation is sparse.

## Install

pip install delta-kernel-rust-sharing-wrapper
uv add delta-kernel-rust-sharing-wrapper
poetry add delta-kernel-rust-sharing-wrapper

## Installing delta-kernel-rust-sharing-wrapper

Before you install: Medium install friction due to compiled wheels for specific platforms (macOS x86_64, macOS ARM64, Linux x86_64, Windows x64). Active maintenance with a recent release (4 days old).

License in practice: Licensed under Apache-2.0 (permissive), allowing commercial use, modification, and distribution with minimal restrictions.

Quickstart:

pip install delta-kernel-rust-sharing-wrapper

import delta_kernel_rust_sharing_wrapper
# Use the wrapper to access Delta Lake tables via Rust kernel

Requires a platform matching one of the provided wheels (macOS 10.12+, macOS 11.0+, Linux glibc 2.28+, or Windows x64); Python 3.10+ (abi3 wheels).

Verify before relying:

- Exact API surface and available methods in the wrapper—the excerpt describes build process but not runtime usage.
- Whether this package is intended for end-user installation or primarily for development/testing within delta-sharing.
- Performance characteristics and typical use patterns compared to pure-Python Delta Lake clients.
