---------------------------------------
https://github.com/apache/incubator-airflow/pull/3620
> Tree view JSON is unnecessarily large
> -------------------------------------
>
> Key: AIRFLOW-2776
> URL: https://issues.apache.org/jira/browse/AIRFLOW-2776
> Project: Apache Airflow
> Issue Type: Improvement
> Reporter: Abdul Nimeri
> Assignee: Abdul Nimeri
> Priority: Minor
>
> The tree view generates JSON that can be massive for bigger DAGs –– some of
> our tree views at stripe have 10s of MBs of JSON.
> The [generated JSON is
> prettified|https://github.com/apache/incubator-airflow/blob/52c745da71a6da798f7322956967b5e818b56e48/airflow/www/views.py#L1480],
> which both takes up more CPU time during serialization, as well as slowing
> everything else that uses it. We patched this on stripe's fork by removing
> all whitespace and had a ton of speedup for bigger tree views. Considering
> the JSON is only meant to be used programmatically, this is probably an easy
> win.
