Advisor: Prof. Guoliang Li
Tsinghua Database Group


I am Xuanhe Zhou (周煊赫 in Chinese). My research interest lies in autonomous database systems, i.e., automating and optimizing the logical/physical designs of database systems so as to benefit AI/DB users. The relevant research problems include but are not limited to : (1) Self-monitoring (e.g., trend forecasting, performance prediction); (2) Self-optimization (e.g., query rewrite); (3) Self-configuration (e.g., knob/index/partition management), (4) Learned data structure design (e.g., learned indexes), and (5) Autonomous database frameworks. Additionally, I also explore interesting AI techniques that are relevant to databases (e.g., real-time feature stores).


A corpus of training data for database tasks! (coming soon)


One of our current targets is to open-source a series of practical, out-of-the-box tools (outside/inside database kernels) for both AI and DB users with my excellent collaborators, e.g.,

👉 Database Tools

Applications: Zhenzhi (banking); Enmotech (complex sqls on oracle)
Applications: PSBC (banking)
Applications: CMCC (telecommunications); Huawei Cloud;

👉 Database Strategies

👉 AI Assistant Tools

Applications: 4Paradigm (feature store); Intel (new hardware testing); Vipshop (feature store)
