Data Lakes
When organizations collect terabytes or petabytes of raw information from apps, sensors, and user activity, they need a system that can store it all, structured or not.
That’s where Data Lakes come in.
In this chapter, we’ll explore what data lakes are, how they evolved, how they differ from data warehouses, their architecture, ingestion pipelines, governance strategies, and how modern cloud platforms like AWS, Azure, and Google Cloud implement them at scale.
