Machine learning enhances self-tuning data pipelines by optimizing Directed Acyclic Graphs (DAGs) for cost, speed, resilience, and data quality. It automatically adjusts pipeline parameters, identifies inefficiencies, and suggests improvements based on historical data. By predicting bottlenecks, resource consumption, and potential failures, machine learning ensures smoother execution and faster processing times. It can also detect anomalies, ensuring data quality is maintained while minimizing errors. This optimization reduces operational costs, enhances system performance, and guarantees more reliable, scalable workflows, protecting revenue by ensuring timely and high-quality data delivery. As a result, businesses can achieve greater efficiency and lower overhead.
