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

             Summary: Scheduler DB Queries Should be Batched
                 Key: AIRFLOW-1980
                 URL: https://issues.apache.org/jira/browse/AIRFLOW-1980
             Project: Apache Airflow
          Issue Type: Bug
          Components: scheduler
            Reporter: Dan Davydov


DB queries in the scheduler should be batched, since the larger ones can get 
quite big and cause lock wait timeouts.

One example is the queries in the _change_state_for_tis_without_dagrun function 
in jobs.py
