Usage Example

This processor routes FlowFiles based on their attributes using the NiFi Expression Language. Users add properties with valid NiFi Expression Language Expressions as the values. Each Expression must return a value of type Boolean (true or false).

Example: The goal is to route all files with filenames that start with ABC down a certain path. Add a property with the following name and value:

  • property name: ABC
  • property value: ${filename:startsWith('ABC')}

In this example, all files with filenames that start with ABC will follow the ABC relationship.
