Hi @Matthew Gaetano There's another feature in the UpdateProcessor that you can use which Rules : https://nifi.apache.org/docs/nifi-docs/components/org.apache.nifi/nifi-update-attribute-nar/1.4.0/org.apache.nifi.processors.attributes.UpdateAttribute/additionalDetails.html This feature is available in the advanced settings and you can use to define conditions and actions. So you can say if condition than update timestamps, else do not. Look at my answer to this question to see how you can use it : https://community.hortonworks.com/questions/140060/nifi-how-to-load-a-value-in-memory-one-time-from-c.html?childToView=140233#answer-140233 ...

I am not sure I understand your use case. Why do you use UnpackContent after Compress ? CompressContent can decompress your gz file with the decompress option. ... View more
