Jim,
${filename} is a NiFi expression language that is used to get the name of
the flowfile that is in the flow. For ex: assume this simple pipeline.
GetFile -> UpdateAttribute -> PutFile. GetFile will read the files from the
input directory and each flowfile will have an attribute ‘filename’
Hey all,
I'm a bit of a newbie to nifi . But I am hoping someone might have
some advice for me here. I am using the ListS3 processor and the prefix
field just doesn't seem to like anything but static filenames. I cannot
reference directories or use the nifi expression language, where the docs
say
