-----------------------------------

             Summary: Concurrency calculation in scheduler is slow and has a bug
                 Key: AIRFLOW-4419
                 URL: https://issues.apache.org/jira/browse/AIRFLOW-4419
             Project: Apache Airflow
          Issue Type: Improvement
            Reporter: Kevin Yang
            Assignee: Kevin Yang


The pool, dag and task concurrency calculation logic is slow and can be optimized. Also current task concurrency should not increase if the executor already has the task.
