             Summary: Fix IN-predicate sqlalchemy warning
                 Key: AIRFLOW-1237
             Project: Apache Airflow
          Issue Type: Bug
          Components: db
    Affects Versions: 1.8.0
            Reporter: Stanislav Kudriashev
            Assignee: Stanislav Kudriashev
             Fix For: 1.9.0

SAWarning: The IN-predicate on "dag_stats.dag_id" was invoked with an empty sequence. This
results in a contradiction, which nonetheless can be expensive to evaluate.  Consider alternative
strategies for improved performance.
