Processing data through a pipeline offers a range of advantages, and one significant benefit is that it streamlines the data handling process. This means that data can be collected, transformed, and analyzed in a cohesive flow, allowing for improved efficiency and effectiveness. By organizing the data processing into a structured sequence of steps, pipelines enable smoother transitions between stages, reduce the complexity of handling data manually, and minimize the potential for errors.

In a well-designed pipeline, data can automatically move through various transformations, aggregations, and treatments without requiring human intervention at each step. This automated workflow enhances productivity and allows teams to focus on higher-level tasks, such as analysis or modeling, rather than on repetitive data management tasks. Additionally, streamlined pipelines can result in more timely insights since data is continuously processed and made available as it flows through the system.

While automating machine learning training is beneficial and a characteristic of some data pipelines, the central advantage of a pipeline concerns the holistic approach to managing data rather than isolating one specific task. Reducing data access times might be a part of an optimized pipeline but is not its primary benefit. Lastly, completely eliminating data storage needs is impractical, as data needs to be stored at least temporarily for processing and analysis. Hence, the focus
