> Disable unused flask-sqlalchemy modification tracking form webserver

> Key: AIRFLOW-3891
> URL: https://issues.apache.org/jira/browse/AIRFLOW-3891
> Project: Apache Airflow
> Issue Type: Improvement
> Reporter: Josh Carp
> Assignee: Josh Carp
> Priority: Trivial
> Fix For: 1.10.3
>
>
> By default, flask-sqlalchemy tracks model changes for its event system, which
> adds some overhead. Since I don't think we're using the flask-sqlalchemy
> event system, we should be able to turn off modification tracking and improve
> performance.
