Delta Lake

Delta Lake is an open-source storage layer that enhances data lakes by adding reliability, consistency, and performance. It allows organizations to store large amounts of data in a single system while ensuring data is accurate, complete, and ready for analysis. Delta Lake manages data changes efficiently, supports ACID transactions (like in databases), and provides features such as data versioning and time travel. This makes it easier to update, query, and maintain big data, enabling faster insights and better decision-making without sacrificing data quality.
