Automatic Configuration Tuning on Cloud Database: A Survey
CoRR(2024)
摘要
Faced with the challenges of big data, modern cloud database management
systems are designed to efficiently store, organize, and retrieve data,
supporting optimal performance, scalability, and reliability for complex data
processing and analysis. However, achieving good performance in modern
databases is non-trivial as they are notorious for having dozens of
configurable knobs, such as hardware setup, software setup, database physical
and logical design, etc., that control runtime behaviors and impact database
performance. To find the optimal configuration for achieving optimal
performance, extensive research has been conducted on automatic parameter
tuning in DBMS. This paper provides a comprehensive survey of predominant
configuration tuning techniques, including Bayesian optimization-based
solutions, Neural network-based solutions, Reinforcement learning-based
solutions, and Search-based solutions. Moreover, it investigates the
fundamental aspects of parameter tuning pipeline, including tuning objective,
workload characterization, feature pruning, knowledge from experience,
configuration recommendation, and experimental settings. We highlight technique
comparisons in each component, corresponding solutions, and introduce the
experimental setting for performance evaluation. Finally, we conclude this
paper and present future research opportunities. This paper aims to assist
future researchers and practitioners in gaining a better understanding of
automatic parameter tuning in cloud databases by providing state-of-the-art
existing solutions, research directions, and evaluation benchmarks.
