Relationships:
Name | Description |
original | The original FlowFile is sent to this relationship after it has been successfully unpacked |
failure | The original FlowFile is sent to this relationship when it cannot be unpacked for some reason |
success | Unpacked FlowFiles are sent to this relationship |
Reads Attributes:
Name | Description |
mime.type | If the <Packaging Format> property is set to use mime.type attribute, this attribute is used to determine the FlowFile's MIME Type. In this case, if the attribute is set to application/tar, the TAR Packaging Format will be used. If the attribute is set to application/zip, the ZIP Packaging Format will be used. If the attribute is set to application/flowfile-v3 or application/flowfile-v2 or application/flowfile-v1, the appropriate FlowFile Packaging Format will be used. If this attribute is missing, the FlowFile will be routed to 'failure'. Otherwise, if the attribute's value is not one of those mentioned above, the FlowFile will be routed to 'success' without being unpacked |
Writes Attributes:
Name | Description |
mime.type | If the FlowFile is successfully unpacked, its MIME Type is no longer known, so the mime.type attribute is set to application/octet-stream. |
fragment.identifier | All unpacked FlowFiles 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 unpacked FlowFiles that were created from a single parent FlowFile |
fragment.count | The number of unpacked FlowFiles generated from the parent FlowFile |
segment.original.filename | The filename of the parent FlowFile. Extensions of .tar, .zip or .pkg are removed because the MergeContent processor automatically adds those extensions if it is used to rebuild the original FlowFile |
