Data Lake / Lakehouse Guide: Powered by Data Lake Table Formats (Delta Lake, Iceberg, Hudi)

A data lake stores vast amounts of unstructured and semi-structured data, enabling easier analytics and machine learning processes. A data lakehouse combines the flexibility and cost-efficiency of data lakes with the data management features of data warehouses. Key technologies in this space include Delta Lake, Apache Iceberg, and Hudi, each providing essential database-like features on top of distributed storage formats. The market for these technologies is rapidly evolving with major support from companies like AWS, Google Cloud, and Databricks.
