Reviewing the examples in the repository, I noticed there's no instance of managing schema changes for incremental data loading.
To elaborate, if columns are added or removed in the source table and these changes need to be mirrored in the target tables, it's straightforward when dealing with full data loads and recreating the target table each time.
