Stream Schema MergeDescription
The Stream Schema Merge transform merges multiple inputs with different structures and creates a combination of fields.
Tip
If the streams to merge contain fields with the same name but different types, these fields with be combined into a single field of type String.
If you want to make sure fields keep their original data type, make sure to convert them to identical types. e.g. through the Metadata tab in the Select Values transform.
