Splits, or partitions, record-oriented data based on the configured fields in the data. One or more properties must be added. The name of the property is the name of an attribute to add. The value of the property is a RecordPath to evaluate against each Record. Two records will go to the same outbound FlowFile only if they have the same value for each of the given RecordPaths. Because we know that all records in a given output FlowFile have the same value for the fields that are specified by the RecordPath, an attribute is added for each field. See Additional Details on the Usage page for more information and examples.

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.

Supports Sensitive Dynamic Properties: No
Dynamic Properties allow the user to specify both the name and value of a property.
| Name | Value | Description |
|---|---|---|
| The name given to the dynamic property is the name of the attribute that will be used to denote the value of the associated RecordPath. | A RecordPath that points to a field in the Record. | Each dynamic property represents a RecordPath that will be evaluated against each record in an incoming FlowFile. When the value of the RecordPath is determined for a Record, an attribute is added to the outgoing FlowFile. The name of the attribute is the same as the name of this property. The value of the attribute is the same as the value of the field in the Record that the RecordPath points to. Note that no attribute will be added if the value returned for the RecordPath is null or is not a scalar value (i.e., the value is an Array, Map, or Record). Supports Expression Language: true (will be evaluated using flow file attributes and variable registry) |
| Name | Description |
|---|---|
| success | FlowFiles that are successfully partitioned will be routed to this relationship |
| failure | If a FlowFile cannot be partitioned from the configured input format to the configured output format, the unchanged FlowFile will be routed to this relationship |
| original | Once all records in an incoming FlowFile have been partitioned, the original FlowFile is routed to this relationship. |
| Name | Description |
|---|---|
| record.count | The number of records in an outgoing FlowFile |
| mime.type | The MIME Type that the configured Record Writer indicates is appropriate |
| fragment.identifier | All partitioned 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 partitioned FlowFiles that were created from a single parent FlowFile |
| fragment.count | The number of partitioned FlowFiles generated from the parent FlowFile |
| segment.original.filename | The filename of the parent FlowFile |
| <dynamic property name> | For each dynamic property that is added, an attribute may be added to the FlowFile. See the description for Dynamic Properties for more information. |
