@Matt Clarke This is an excellent answer, thank you very much. I am indeed using a cluster of nifi nodes, and my dataflow starts with a list/fetch as described by the answer of @Pierre Villard on this question : https://community.hortonworks.com/questions/52112/nifi-load-distribution-in-getfile-processor.html So the beginning of my dataflow looks like this : I am using the list/fetch pattern to take advantage of the cluster and improve the performance of the ingestion. This leads me to ask the following question which is probably beyond the scope of the initial question and should be asked in the different post, but I am putting it here so that everyone in the same situation profits from your beautiful answers : does this mean that I can't use the merge content processor in these kind of dataflows (dataflows thar run on all nodes), as I don't have a way to control the node that will ingest a pair of matching flowfiles (flowfiles that have the same "cle" attribute) ? or could you think of a trick to handle this ? Thanks again for your help ! ... View more

@Jeff Storck yes the processor was stopped just to take the screenshots (I left it for running for 1 day and the two files didn't merge). And yes smaller files merge (15MB files merge for example). ... View more

Hi @Constantin Stanca, I changed the back pressure data size to 2GB but the two flowfiles still don't merge ... ... View more

Hi @Jeff Storck, the correlation attribute is present on both flowfiles and its value is the same. Also, I am sure that for a correlation attribute value, only two flowfiles will have that value. So with my settings : Minimum number of entries = 2, maximum number of entries = 2, I am sure that only those two flowfiles will merge. Still, in my case the two flowfiles in the screenshot stay infinitely in the queue ... I am pretty sure it's a size problem, but can't figure it out. ... View more
