Summary
🤩
Rockstar🎓
Top SchoolXinye Tao is a Data Platform Engineer with nine years of experience building high-performance storage and database systems, currently driving data platform work at Metabit Trading in Shanghai. Previously at PingCAP he improved TiKV performance and cloud readiness, authored a Raft-based log engine that cut I/O and latency, and scaled RocksDB usage for thousands of instances. An active open-source Rust contributor, Xinye has added Clippy lints and advanced features to rust-rocksdb and TiKV/Titan—work that touches both low-level storage rate limiting and blob management. His background spans research and systems engineering from Zhejiang University to Microsoft Research Asia, blending graphics and database roots into pragmatic optimizations that reveal subtle tail-latency and concurrency issues.

tikv/rust-rocksdb
Jun 2019 - Jan 2023
rust wrapper for rocksdb
Role in this project:
Back-end Developer
Back-end DeveloperContributions:122 reviews, 38 commits, 146 PRs in 3 years 8 months
Contributions summary:Xinye primarily contributed to enhancing the functionality of the `rust-rocksdb` library by implementing new features related to rate limiting and background processes. Their work involved adding features like `refill_period` and `WriteAmpBasedRateLimiter`, as well as dynamic modification of the auto-tuned mode of rate limiters. Additionally, the user added options for setting the maximum number of background compactions and flushes. These changes expanded the library's capabilities for managing resource utilization and background tasks.

tikv/titan
May 2019 - Dec 2022
A RocksDB plugin for key-value separation, inspired by WiscKey.
Role in this project:Back-end Developer & Database Engineer
Back-end Developer & Database EngineerContributions:74 reviews, 20 commits, 45 PRs in 3 years 7 months
Contributions summary:Xinye contributed to the `tikv/titan` project, a RocksDB plugin for key-value separation. Their primary contributions include adding configurations for testing, specifically the `min-blob-size` flag, which influences how data is stored. Furthermore, they added a thread safety test to catch data race issues related to column family operations and garbage collection. They also implemented features related to `blob-run-mode`, enabling different operational modes for Titan, and internal stats and metrics for monitoring blob file and live value.
