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

             Summary: Reduce time spent building SQL strings
                 Key: AIRFLOW-5930
                 URL: https://issues.apache.org/jira/browse/AIRFLOW-5930
             Project: Apache Airflow
          Issue Type: Improvement
          Components: scheduler
    Affects Versions: 2.0.0
            Reporter: Ash Berlin-Taylor


My profling of the scheduler work turned up a lot of cases where the 
scheduler_job/dag parser process was spending a lot of time building (not 
executing!) the SQL string.

This can be improved with
