Abstract

Translate Article

Online Analytical Processing (OLAP) is crucial for modern organizations, enabling data-driven decision-making from evergrowing datasets.The increasing volume and complexity of this data present significant challenges to timely and efficient analysis.This paper investigates Amazon Redshift, a highly scalable and performant data warehouse service offered by AWS, as a solution to these challenges.We will examine Redshift's architecture, focusing on its parallel processing capabilities, columnar storage and optimization techniques.Furthermore, we will explore best practices for scaling Redshift deployments to handle heavy analytical workloads and discuss the impact of key design choices, such as data distribution strategies and ETL processes, on overall performance.The research will contribute to a better understanding of how Redshift can effectively address the analytical needs of large organizations.
