I was going through an AWS webinar and I found this slide where they recommend separate your data & schema...they mentioned that if we separate out then it's easy for each to be evolved separately but what's the point in data change without schema change or vice versa? what use cases can have data evolution but not schema evolution or vice versa, appreciate your valuable inputs. I'm working on a lakehouse architecture and this question always haunts me!

  • The data can be stored in any format based on the requirement if kept separate from the schema. Also, schema can be modified without changing the underlying data. – Nadeem Khan Mar 12 '23 at 03:52
