摘 要
本研究针对大数据环境下索引效率的挑战,提出了一种高效索引策略。随着大数据时代的来临,数据处理量激增,传统索引方法已难以满足快速检索的需求。本研究旨在通过设计新型索引策略,优化大数据处理性能,提高查询效率。方法上,我们结合了倒排索引和位图索引技术,同时引入了机器学习算法对索引进行优化。实验采用真实大数据集,对比了传统索引和本研究所提策略。结果显示,新型索引策略在查询速度和准确性上均有显著提升,特别在处理大规模数据集时效果更为显著。此外,本研究还创新性地提出了一种动态调整索引结构的方法,以适应数据变化,进一步提升索引效率。

Abstract
This study presents an efficient indexing strategy for the challenges of indexing efficiency in a big data environment. With the advent of the era of big data, the data processing volume surge, the traditional index method has been difficult to meet the needs of fast retrieval. This study aims to optimize big data processing performance and improve query efficiency by designing novel indexing strategies. Methodologically, we combine the inverted index and bitmap indexing techniques, while introducing a machine learning algorithm to optimize the index. The experiment uses real large data sets, comparing the traditional index and the proposed strategy of this study. The results showed that the new indexing strategy showed a significant improvement in both the query speed and the accuracy, especially when processing large-scale data sets. Moreover, this study also innovatively proposed a method of dynamically adjust the index structure to adapt to the data changes and further improve the index efficiency.
