Hi Databricks Community,
We've encountered an issue with setting a column only on insert when using DLT's apply_changes CDC merge functionality. It's important to note that this capability is available when using the regular Delta merge operation, specifically through whenNotMatchedInsert option.
If we want to setup a `CreatedDate` on initial insert. Is there any option available to solve this when using apply_changes, similar to how it's achievable with the regular Delta merge operation (https://docs.databricks.com/en/delta/merge.html)?
