Nissim Shiman created NIFI-11388: ------------------------------------ Summary: Backpressure queue settings loosely followed Key: NIFI-11388 URL: https://issues.apache.org/jira/browse/NIFI-11388 Project: Apache NiFi Issue Type: Improvement Reporter: Nissim Shiman
The backpressure settings on connections between processors are only loosely followed. More flowfiles can end up on queues than configured via backpressure setting. For example, set up flow: GenerateFlowFile -> UpdateAttribute -> (some processor) where GenerateFlowFile has _Custom Text_ set to be _hello_ and Run Schedule is set to be _0 min_ and the connection following UpdateAttribute has _Back Pressure Object Threshold_ set to be _100_ Start GenerateFlowFile. Wait a few moments until outgoing connection fills up. Start UpdateAttribute OutGoing conection will have more than 100 flowfiles on it (I had over 1000 on mine when running these steps) -- This message was sent by Atlassian Jira (v8.20.10#820010)
