Local map

You can use local maps to break up a large map into nested groups of mapping elements and process the complex elements of the whole data object.

Local maps are a partial view of a larger map, rather than separate files.

A local map has only one element as input (either a simple type or a complex type), which can contain nested elements. The output can be either a single element or an array element, but it must be a complex type.

The local map does not transform data; you must specify transforms for the input and output elements in the nested map.
