> Superfluous ajax calls when no dags returned in search
> ------------------------------------------------------
>
> Key: AIRFLOW-6268
> URL: https://issues.apache.org/jira/browse/AIRFLOW-6268
> Project: Apache Airflow
> Issue Type: Bug
> Components: ui
> Affects Versions: 2.0.0, 1.10.6
> Reporter: Robin Edwards
> Priority: Minor
> Fix For: 1.10.7
>
>
> When a search for a dag returns no results the system still makes 4 ajax
> calls to: task_stats, dag_stats, last_dagruns and blocked which by default
> return the entire state of the system which is discarded and not used.
> On systems with a large amount of dags and task meta data this results in an
> incredibly slow loading page.
