Abstract: Database parameter tuning techniques are facing great challenge under stringent performance requirements due to the huge data scale and complex application scenarios in big data. Traditional heuristic tuning methods or manual intervention methods are lack of the ability to handle various requirements. The development of machine learning provides a brand-new opportunity for database parameter tuning with its power in learning, reasoning, and planning. Through sufficient investigation, the evolution route of database parameter tuning technology based on machine learning is given. According to the thought of content-problem-resolution, this paper describes the traditional parameter tuning techniques and the parameter tuning techniques based on Bayesian optimization (BO) model and reinforcement learning (RL), and the future research directions are proposed as well. Hopefully, this paper can provide some valuable references for researchers in this field.
