tikv/client-rust
Nov 2018 - Jun 2022
Rust Client for TiKV.
Role in this project:
Back-end Developer
Back-end DeveloperContributions:4 reviews, 6 commits, 8 PRs in 3 years 7 months
Contributions summary:Lucas primarily focused on implementing the Rust client for the TiKV key-value store. They contributed to the core functionality by defining and implementing various client operations such as `Get`, `Put`, `Delete`, and `Scan` operations, using futures for asynchronous operations. The user also made code improvements by documenting public code, reducing the public surface, and refactoring, which suggests a focus on code quality and maintainability. They also worked on refining the API, including refactoring requests to an enum and changing the `get` function to return `Option<Value>`.

tikv/tikv
Apr 2018 - Jun 2022
Distributed transactional key-value database, originally created to complement TiDB
Role in this project:Back-end Developer
Back-end DeveloperContributions:17 reviews, 19 commits, 15 PRs in 4 years 3 months
Contributions summary:Lucas made significant contributions to the `tikv/tikv` repository, a distributed key-value database. Their work included implementing new functionalities like raw batch operations (put/get/delete/scan), which likely involved modifying core storage components. They also improved the PD client, fixing typos, and making optimizations. Furthermore, they addressed issues and added failpoints related to log file rotation.
