robinedwards commented on pull request #6730: [AIRFLOW-6095] Filter dags
returned by task_stats
URL: https://github.com/apache/airflow/pull/6730
Add dag_ids parameter to task_stats so can filter by a set of dag_ids
present on the dags view. This is intended to speed up the response time
and reduce the size of the payload when running a large number of dags.
(cherry picked from commit 2b11f55b406d38b59c3062ad75826ad6c1b1fdb9) this
back ports the functionality from master in to v1-10-test

> Task stats endpoint is slow and returns a large payload

> Key: AIRFLOW-6095
> URL: https://issues.apache.org/jira/browse/AIRFLOW-6095
> Project: Apache Airflow
> Issue Type: Improvement
> Components: api, ui
> Affects Versions: 2.0.0, 1.10.6
> Reporter: Robin Edwards
> Assignee: Robin Edwards
> Priority: Minor
> Fix For: 1.10.7

>
> The task_stats endpoint returns all dags by default. This can result in an
> extremely large payload ~ 8mb and slow response time when you have a lot of
> dags (In this case 1500+).
> The accompanying pull request adds a dag_ids get parameter to the task_stats
> end point which is populated by the dags present on the page.
> If this is accepted I intend to provide the equivalent change to the
> dag_stats and last_dagruns endpoints
