The ApplyTransformMarkLogic processor is similar to QueryMarkLogic but is instead used to modify documents that match a query. The processor depends on a MarkLogic REST transform for modifying each document.

The primary use case for this processor is updating a potentially large number of documents in MarkLogic, where the updates can all be handled via a REST transform.
