I continue to think, what if we convert these Pythonic names to Kotlin like? full_name -> fullName?

The problem is the following.
@ColumnNamedoesn't work correctly now, so we can't use in quickstart unforunately, but hope this will be fixed.- We could change column names just after reading using
renameToCamelCasebut I don't want to do that in this guide for better storytelling.
So hopefully we can fix that after fixing @ColumnName.
Now we can write a "standard data preparation in KDF" guide and suggest using renameToCamelCase there.
