Properties

Name	Type	Description
flatten?	boolean | IResolvable	A Boolean value to indicate whether the list will be flattened into single items.
flattenedElement?	string	If you set flatten to true , use flattenedElement to specify which element, first or last , to keep.
key?	string	The key of the field to be extracted as keys in the generated map.
source?	string	The key in the log event that has a list of objects that will be converted to a map.
target?	string	The key of the field that will hold the generated map.
valueKey?	string	If this is specified, the values that you specify in this parameter will be extracted from the source objects and put into the values of the generated map.

target?

Type: string (optional)

The key of the field that will hold the generated map.

valueKey?

Type: string (optional)

If this is specified, the values that you specify in this parameter will be extracted from the source objects and put into the values of the generated map.

Otherwise, original objects in the source list will be put into the values of the generated map.
