@trixpan if you want to add the UUDI of the original FlowFile you would get
it from the attributes:
`String parentUuid =
originalFlowFile.getAttribute(CoreAttributes.UUID.key());`
Then add that to the child FlowFile:
`split = session.putAttribute(split, CoreAttributes.UUID.key(),
parentUUID);`
Is that what you were looking to do?
