Abstract
With the advent of the era of big data, the database system is facing the increasing load pressure, and a reasonable resource allocation strategy is crucial to improve the system performance and stability. This study aims to realize the dynamic optimized allocation of database resources through accurate load prediction. We propose a machine learning-based load prediction model that can accurately predict the database load over a future time period. Meanwhile, combined with the prediction results, we designed a dynamic resource allocation algorithm that is able to intelligently adjust the resource allocation according to the predicted load situation to meet the performance requirements of different time periods. The experimental results show that the proposed algorithm effectively reduces the resource consumption and improves the resource utilization rate while ensuring the database performance. The main contribution of this study is that a novel method of load prediction and dynamic resource allocation is proposed, which not only improves the operation efficiency of the database system, but also provides new ideas for the research in related fields.
