puthivestreaming.png I mean only metadata(attributes) without flow files with data.
My Example in puthivestreaming.png, after done processor PutHiveStreaming all flowfiles (with data) send to SelectHiveQL .
Hello! Do you mean use processor ScanAttribute or LogAttribute for to delete superfluous data ? But into LogAttribute processor also send all data, example in LogAttribute.png .
Don't worry about the data. It is not copied everywhere unless you need to change it. The data is actually a pass by reference. When a flow file is passed from one processor to another, the upstream processor passes a reference (to flowfile in content repository) to the second processor. Unless you need to modify the content, make a write etc, there isn't a data movement.
