LanceDB is an open-source project and we welcome contributions from the community. This document outlines the process for contributing to LanceDB.
If you encounter a bug or have a feature request, please open an issue on the GitHub issue tracker.
We track issues on the GitHub issue tracker. If you are looking for something to work on, check the good first issue label. These issues are typically the best described and have the smallest scope.
If there's an issue you are interested in working on, please leave a comment on the issue. This will help us avoid duplicate work. Additionally, if you have questions about the issue, please ask them in the issue comments. We are happy to provide guidance on how to approach the issue.
First, fork the repository on GitHub, then clone your fork:
git clone https://github.com/<username>/lancedb.git
cd lancedb
Then add the main repository as a remote:
git remote add upstream https://github.com/lancedb/lancedb.git
git fetch upstream
We have development environments for Python, Typescript, and Java. Each environment has its own setup instructions.
For the best chance of having your pull request accepted, please follow these guidelines:
- Unit test all bug fixes and new features. Your code will not be merged if it doesn't have tests.
- If you change the public API, update the documentation in the
docs
directory. - Aim to minimize the number of changes in each pull request. Keep to solving one problem at a time, when possible.
- Before marking a pull request ready-for-review, do a self review of your code. Is it clear why you are making the changes? Are the changes easy to understand?
- Use conventional commit messages as pull request titles. Examples:
- New feature:
feat: adding foo API
- Bug fix:
fix: issue with foo API
- Documentation change:
docs: adding foo API documentation
- New feature:
- If your pull request is a work in progress, leave the pull request as a draft. We will assume the pull request is ready for review when it is opened.
- When writing tests, test the error cases. Make sure they have understandable error messages.
The core library is written in Rust. The Python, Typescript, and Java libraries are wrappers around the Rust library.
