The MQTT Consumer step requires Setup, Security, Batch, Fields, Result fields, and Options definitions to stream messages.

Enter the following information for the Step Name and Transformation fields:

Option	Description
Step name	Specifies the unique name of the step on the canvas. The Step name is set to MQTT Consumer by default.
Transformation	Specify the child transformation to execute by performing any of the following actions: Entering its path Clicking Browse to select an existing child transformation Clicking New to create and save a new child transformation. See Create and Save a New Child Transformation for more details. If you select a transformation that has the same root path as the current transformation, the variable`${Internal.Entry.Current.Directory}` is automatically inserted in place of the common root path. For example, if the current transformation's path is: /home/admin/transformation.ktr and you select a transformation in the directory /home/admin/path/sub.ktr, then the path is automatically converted to: `${Internal.Entry.Current.Directory}`/path/sub.ktr If you are working with a repository, you must specify the name of the transformation. If you are not working with a repository, you must specify the XML file name of the transformation. Transformations previously specified by reference are automatically converted to be specified by the transformation name in the Pentaho Repository.
