RouteOnAttribute
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.
