Filter flowfiles by size from RouteOnAttribute
Is there a way to get access to the flowfile size from EL? This said to use
Content-Length, but that didn't appear to work for me on 1.8.0.

Thanks,

Andy, FWIW I just edited the question to put a prominent note directing
anyone who sees it to review your answer.

This totally worked for me! It is used to filter out the flow files with 0
bytes. It allows flow files with size greater than zero.

Ha, I went to see if we could add a more helpful answer there and I see I’ve been there before. The question’s author selected the incorrect answer as most helpful to them. Content-Length is not a core attribute and would only exist in a scenario where a previous processor populated it.

Mike,
You can reference ${fileSize}. This is the size of a FlowFile in bytes.
Thanks
