Answer: Lakehouse supports schema enforcement and evolution
The correct answer is that a lakehouse supports schema enforcement and evolution. Unlike traditional big data systems that can only enforce a schema on read, a lakehouse using Delta Lake can enforce a schema on write and also supports evolving schema over time. This allows for flexible data management, including adding new columns, evolving nested columns, and changing data types. For example, the Dataframe writer API supports different modes of schema enforcement and evolution, such as Default (only enforcement), Merge (supports enforcement and evolution), and Overwrite (no enforcement). This flexibility is a key feature of the lakehouse architecture.
