Flow File attributes are held in memory (in addition to being persisted to disk) so more attributes means more Java objects on the heap, means more garbage collection pressure. I don't think there is any way to set what the limit is because it depends on how much data is in the attributes, how much memory you have, how many flow files, etc.</P> Wed, 26 Oct 2016 01:15:33 GMT https://community.cloudera.com/t5/Archives-of-Support-Questions/Nifi-Attribute-Limit/m-p/149247#M44491 bbende 2016-10-26T01:15:33Z
