Fairly new with NiFi, looking for information that is just lacking. I'm trying to do what I consider to be a very basic feat. Get a bunch of files. Sort those files by their name or whatever I want. I found the documentation but it is just lacking. For examples, The documentation states to on the 'Initial Order' When the first FlowFile of a group arrives, initial target order will be computed and stored in the managed state. After that, target order will start being tracked by EnforceOrder and stored in the state management store. If Expression Language is used but evaluated result was not an integer, then the FlowFile will be routed to failure, and initial order will be left unknown until consecutive FlowFiles provide a valid initial order. *Supports Expression Language: true (will be evaluated using flow file attributes and variable registry)* and The documentation states to on the 'Order Attribute' A name of FlowFile attribute whose value will be used to enforce order of FlowFiles within a group. If a FlowFile does not have this attribute, or its value is not an integer, the FlowFile will be routed to failure. Neither of these clearly present me with how to use this software. It probably means more to someone who already knew how to do it and it just is a reminder to them but for new people we are left scratching our heads. I've been Googling for 3 hours trying to find an answer. Can you clarify? -- Respectfully, Elijah
