> The "Graph View" has a dropdown which contains all DAG run IDs. If there are
> many (thousands) of DAG runs the page gets barely usable. It takes multiple
> seconds to load the page because all DAG runs must be fetched from DB, are
> processed, and a long option list is rendered in the browser. It is also not
> very useful because in such a long list it is hard to find a particular DAG
> run.
> A simple fix to address the load time would be to just limit the number of
> shown DAG runs. For example only the latest N are shown, N could be
> "page_size" from airflow.cfg which is also used in other views. If the DAG
> run that should be shown (via query parameters execution_date or run_id) is
> not included in the N lastest list it can still be added by a 2nd SQL query.
> A more complex change to improve usability would require a different way to
> select a DAG run. For example a popup to search for DAG runs with pagination
> etc. But such functionality already exits in the /dagrun UI.
