Properties:
In the list below, the names of required properties appear in bold. Anyother properties (not in bold) are considered optional. The table also indicates any default values, whether a property supports the NiFi Expression Language (or simply EL), and whether a property is considered "sensitive", meaning that its value will be encrypted. Before entering a value in a sensitive property, ensure that the nifi.properties file has an entry for the property nifi.sensitive.props.key.
| Name | Description | Default Value | Valid Values | EL | Sensitive |
|---|---|---|---|---|---|
| Dictionary File | A new-line-delimited text file that includes the terms that should trigger a match. Empty lines are ignored. | No | No | ||
| Attribute Pattern | Regular Expression that specifies the names of attributes whose values will be matched against the terms in the dictionary | .* | No | No | |
| Match Criteria | If set to All Must Match, then FlowFiles will be routed to 'matched' only if all specified attributes' values are found in the dictionary. If set to At Least 1 Must Match, FlowFiles will be routed to 'matched' if any attribute specified is found in the dictionary | At Least 1 Must Match |
| No | No |
| Dictionary Filter Pattern | A Regular Expression that will be applied to each line in the dictionary file. If the regular expression does not match the line, the line will not be included in the list of terms to search for. If a Matching Group is specified, only the portion of the term that matches that Matching Group will be used instead of the entire term. If not specified, all terms in the dictionary will be used and each term will consist of the text of the entire line in the file | No | No |
