Introduction

Data pipelines are the backbone of modern data architecture, enabling the flow of data from various sources to systems that can process, analyze, and derive insights. As organizations increasingly rely on large volumes of data from diverse sources, building scalable and efficient data pipelines has become essential. This course is designed for data engineers, architects, and developers who want to understand how to design, implement, and optimize data pipelines that can scale seamlessly as data volume, variety, and velocity increase.
