DataMapper: Supplemental Topics

DataMapper will continue to be fully supported in all current and future versions of Mule ESB 3.x, however it will be removed in Mule 4.0 in favour of the Transform Message component (based on DataWeave code). We recommend that if you wish to take advantage of the new capabilities of DataWeave or if you start new projects, upgrade now.

A migration tool is now included in Studio, which assists in converting a DataMapper map to DataWeave. Right click on a DataMapper, select Migrate to DataWeave, and follow the instructions.

If you don’t see DataMapper on your palette, you can enable it by going to Preferences → Anypoint Studio → Palette Profiles and ticking the checkbox Show deprecated Mule Components and Attributes.

The following topics are likely to be of interest to advanced users of the Anypoint DataMapper Transformer.
