The transform needs to support streaming data to disk to resolved this.

Locate the Enhanced JSON Output transform and reproduce the OutOfMemoryException with a file larger than available memory. Trace how the transform currently writes output and verify that large pipeline outputs can be written to disk without requiring the entire file in memory.
