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.
