Schema evolution is not supported in Delta Lake, necessitating the creation of a new pipeline for each schema change, which increases operational complexity and cost.

Implementing custom application logic to manually detect schema changes and adjust the data pipeline accordingly, which requires extensive development effort and maintenance.

Utilizing Delta Lake's native support for schema evolution to automatically accommodate schema changes, such as adding new columns, without impacting existing data or requiring pipeline modifications.

Creating a new Delta Lake table with the updated schema for each change and manually migrating data from the old table, which is time-consuming and inefficient.
