Hey, Thanks for the answer.
I see. I understand that the file will not be loaded to memory, but there's assumption that the file is present on the filesystem local to the process where Camel runs which is not the case in my scenario. I will happily contribute the patch. Thank you for all the info and links. Super helpful.
