Advisor: Prof. Guoliang Li
Tsinghua Database Group


I am Xuanhe Zhou (周煊赫 in Chinese). My research interest is in autonomous database systems, i.e., automating and optimizing the logical/physical designs of database systems so as to benefit AI/DB users. The detailed 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) and (4) autonomous database system frameworks. Besides, any db-oriented AI techniques are kept in mind.


A corpus of training data for database tasks!


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.,
