[jira] [Created] (NIFI-7678) Stateless NiFi does not properly manage process sessions, leading to memory leak and poor performance

Mark Payne created NIFI-7678:
--------------------------------

             Summary: Stateless NiFi does not properly manage process sessions, leading to memory leak and poor performance
                 Key: NIFI-7678
                 URL: https://issues.apache.org/jira/browse/NIFI-7678
             Project: Apache NiFi
          Issue Type: Bug
            Reporter: Mark Payne
            Assignee: Mark Payne
             Fix For: 1.12.0


Stateless NiFi keeps track of all created Process Sessions and holds them in memory without ever releasing them, instead of removing them from a List after the processor completes. This results in very poor performance and will eventually exhaust the heap
