Subject [jira] [Commented] (AIRFLOW-2086) The tree view page is too slow when display big dag.
Date Wed, 09 May 2018 15:48:00 GMT


ASF subversion and git services commented on AIRFLOW-2086:

Commit 2a55ffe0cd2c04fde2eecdbeff2fa727067069e1 in incubator-airflow's branch refs/heads/master
from Tao feng
[;h=2a55ffe ]

[AIRFLOW-2086][AIRFLOW-2393] Customize default dagrun number in tree view

Closes #3279 from feng-tao/reduce-tree-view

This introduces a new configuration variable to set the default
number of dag runs displayed in the tree view. For large DAGs, this
could cause timeouts in the webserver.
