------------------------------------
Resolution: Fixed
> Main DAG list page does not scale using client side paging
> ----------------------------------------------------------

> Key: AIRFLOW-1519
> URL: https://issues.apache.org/jira/browse/AIRFLOW-1519
> Project: Apache Airflow
> Issue Type: Bug
> Components: ui
> Reporter: Edgar Rodriguez
> Assignee: Edgar Rodriguez
> Fix For: 1.9.0

>
> Airflow's main page with DAGs listing takes too long to load (> 10 secs) when
> scale in number of DAGS increases to 1K+ DAGs.
> Airflow's main page with DAGs listing performs client side paging, by loading
> all dags in the system and loading them to the jquery.DataTable plugin, which
> is pretty slow processing the elements within the DOM in the client's
> browser. Additionally, when there are 1K+ DAGs, rendering them in the server
> side via flask templates also introduces some overhead.
> Solution would be to do a server side paging and aligning the page size to
> the one configured for the web server (see
> https://github.com/apache/incubator-airflow/commit/04bfba3aa97deab850c14763279d33a6dfceb205),
> providing consistent paging across the system.
