About the Data Partition Action

The Data Partition Action works by mapping the fields from one data message to another. This is based upon the fields as defined in the source and destination dataset definitions. The source dataset definition is based upon the specific tracking service or connection that the action is associated with. The user then selects the destination dataset definition for the action. This may be the same, or different from, the source dataset definition.

Once both the dataset definitions are known, then the mapping can be created. Field mapping is the assignment of a source field for a destination field. Each field in the destination can be assigned a source field. A destination field can also have no source—which means that it will create an empty field. In addition, two or more destination fields can be assigned the same source field. The following diagrams illustrate two possible field mappings.

Note that the data types of the two columns mapped together sometimes must be identical, such as in the case of shapes, but can sometimes differ, such as in the case of integers and real numbers.
