What is Data Lake?
A data lake is a centralized storage repository that holds large amounts of raw data in its native format, including structured, semi-structured, and unstructured data. Unlike a data warehouse, a data lake does not enforce a schema on ingestion. Data is stored cheaply at scale and processed when needed, which enables flexibility for future analysis.
