SegmentContent
Description
Segments a FlowFile into multiple smaller segments on byte boundaries. Each segment is given the following attributes: fragment.identifier, fragment.index, fragment.count, segment.original.filename; these attributes can then be used by the MergeContent processor in order to reconstitute the original FlowFile

| fragment.index | A one-up number that indicates the ordering of the segments that were created from a single parent FlowFile |
| segment.original.filename | The filename of the parent FlowFile |
