[jira] [Created] (AIRFLOW-5343) pool_pre_ping support for SQLAlchemy connection

Igor Khrol created AIRFLOW-5343:
-----------------------------------

             Summary: pool_pre_ping support for SQLAlchemy connection
                 Key: AIRFLOW-5343
                 URL: https://issues.apache.org/jira/browse/AIRFLOW-5343
             Project: Apache Airflow
          Issue Type: Task
          Components: configuration
    Affects Versions: 1.10.4
            Reporter: Igor Khrol


SQLalchemy supports connection check while returning it from the pool. There is a need to allow this parameter (`pool_pre_ping`) while creating the connection to database.
