Optimizing Extract Transform Load (ETL) Processes for Real Time Data Warehousing

Uranta Inyingi Allwell, Prof A E Bestman, Nwosu Promise Uwadiegwu

Abstract

This paper on optimizing Extract, Transform, Load (ETL) for real-time data warehousing explored the relationship between ETL optimization and performance outcomes in real-time analytics systems. The objective of this paper was to examine how the dimensions of ETL optimization specifically data quality and scalability influence key performance measures such as data latency and data throughput. To achieve this objective, the paper conducted an extensive review of current literature and applied qualitative content analysis. Based on this analysis, the paper found that while many optimization techniques improve speed, they often compromise data integrity and system scalability, undermining the value of real-time insights. The paper concluded that effective ETL optimization must balance speed with reliability and adaptability to support high-frequency, low-latency data environments. Furthermore, organizations should embed automated quality checks and scalable architectures into ETL workflows to ensure consistent, high-performance real-time data warehousing that enables timely and data-driven decision-making.
