Description¶
Splits a JSON File into multiple, separate FlowFiles for an array element specified by a JsonPath expression. Each generated FlowFile is comprised of an element of the specified array and transferred to relationship ‘split,’ with the original file transferred to the ‘original’ relationship. If the specified JsonPath is not found or does not evaluate to an array element, the original file is routed to ‘failure’ and no files are generated.
