AW: Delete FlowFile content

[Dobbernack, Harald (Key-Work)]

My choice in the past for such a case was  AttributesToJSON with 
Destination=flowfile-content thinking that this really quickly gets rid of 
large content, albeit replacing it with a small json …  don’t know  if this is 
better or worse performance wise than ReplaceText, but it does get the job done…

Easiest way is to use ReplaceText. But put the replacement strategy (may not be 
exactly the name of the property) to Always Replace instead of Regex Replace. 
That should be extremely fast.

Hi to all,

what is the best way to delete flowfiles content so that flowfile
keeps attributes, but to not take space in next relationship between
two processors?

I found this:

https://stackoverflow.com/questions/53312069/what-is-a-fastest-way-to-remove-nifi-flowfile-content

But then flowfile will be striped off the attributes and lineage is lost.

I tried also ReplaceText to replace with Empty string, but I have large files
in the flow, so it is extremely slow.

Thanks,

Tom
