Answer: CDF can help manage schema evolution and data consistency by tracking changes and applying them consistently across sources.
CDF can play a crucial role in managing schema evolution and data consistency by tracking changes and applying them consistently across multiple data sources. This involves enabling CDF on the Delta Lake tables and using the change data to handle schema changes and ensure data consistency. This approach simplifies complex data processing scenarios and ensures robust data management.

Discuss the role of CDF in handling complex data processing scenarios, such as merging multiple data sources with varying schemas. Describe how you would use CDF to manage schema evolution and data consistency in such scenarios, including any necessary code changes to implement this approach.
A
CDF is not useful for managing schema evolution; manual intervention is required.
B
CDF can help manage schema evolution and data consistency by tracking changes and applying them consistently across sources.
C
Schema evolution is not supported in Delta Lake; data must be manually transformed.
D
CDF only handles simple data changes; complex scenarios require custom solutions.
