The article focuses on Delta Lake, an open-source storage layer that improves data lakes by adding reliability and governance features typically found in data warehouses. It explains how Delta Lake allows users to create Delta tables, perform essential data operations like inserts and updates, and utilize innovative features like schema enforcement and time travel for querying historical data. By combining the scalable nature of data lakes with the robustness of data warehouses, Delta Lake addresses common consistency issues faced in Spark workloads, making it a suitable solution for modern data pipelines.
Delta Lake enables users to create a Delta table, perform various data manipulation operations, and query historical data, ensuring data reliability and governance.
The combination of a data lake's scalability and a data warehouse's capabilities makes Delta Lake an ideal choice for modern data engineering pipelines.
With Delta Lake's time travel feature, users can easily query older versions of their data, providing valuable insights and reverting to previous states when needed.
Schema enforcement in Delta Lake mitigates data consistency issues commonly encountered in Spark workloads, leading to more reliable data processing.
