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

Tags:

segment, split

Properties:

In the list below, the names of required properties appear in bold. Any other properties (not in bold) are considered optional. The table also indicates any default values.

Name	Default Value	Allowable Values	Description
Segment Size			The maximum data size for each segment

Relationships:

Name	Description
segments	All segments will be sent to this relationship. If the file was small enough that it was not segmented, a copy of the original is sent to this relationship as well as original
original	The original FlowFile will be sent to this relationship

Reads Attributes:

None specified.

Writes Attributes:

Name	Description
segment.identifier	All segments produced from the same parent FlowFile will have the same randomly generated UUID added for this attribute. This attribute is added to maintain backward compatibility, but the fragment.identifier is preferred, as it is designed to work in conjunction with the MergeContent Processor
segment.index	A one-up number that indicates the ordering of the segments that were created from a single parent FlowFile. This attribute is added to maintain backward compatibility, but the fragment.index is preferred, as it is designed to work in conjunction with the MergeContent Processor
segment.count	The number of segments generated from the parent FlowFile. This attribute is added to maintain backward compatibility, but the fragment.count is preferred, as it is designed to work in conjunction with the MergeContent Processor
fragment.identifier	All segments produced from the same parent FlowFile will have the same randomly generated UUID added for this attribute
fragment.index	A one-up number that indicates the ordering of the segments that were created from a single parent FlowFile
fragment.count	The number of segments generated from the parent FlowFile
segment.original.filename	The filename of the parent FlowFile
segment.original.filename	The filename will be updated to include the parent's filename, the segment index, and the segment count
