robinedwards commented on pull request #6684: [AIRFLOW-6095] Filter dags
returned by task_stats
URL: https://github.com/apache/airflow/pull/6684
### Jira
- [x] My PR addresses the following [Airflow
Jira](https://issues.apache.org/jira/browse/AIRFLOW/) issues and references
them in the PR title. For example, "\[AIRFLOW-XXX\] My Airflow PR"
- https://issues.apache.org/jira/browse/AIRFLOW-XXX
- In case you are fixing a typo in the documentation you can prepend your
commit with \[AIRFLOW-XXX\], code changes always need a Jira issue.
- In case you are proposing a fundamental code change, you need to create
an Airflow Improvement Proposal
([AIP](https://cwiki.apache.org/confluence/display/AIRFLOW/Airflow+Improvements+Proposals)).
- In case you are adding a dependency, check if the license complies with
the [ASF 3rd Party License
Policy](https://www.apache.org/legal/resolved.html#category-x).
### Description
- [x] Here are some details about my PR, including screenshots of any UI
changes:
Add dag_ids parameter to task_stats end point so can filter by a set of
dag_ids
present on the page. This is intended to speed up the response time
and reduce the size of the payload when running a large number of dags. I've
experienced this endpoint taking up to 10 seconds and returning a 8mb
(uncompressed) payload for around 1500 dags.
### Tests
- [x] My PR adds the following unit tests:
See test_views.py
### Commits
- [x] My commits all reference Jira issues in their subject lines, and I
have squashed multiple commits if they address the same issue. In addition, my
commits follow the guidelines from "[How to write a good git commit
message](http://chris.beams.io/posts/git-commit/)":
1. Subject is separated from body by a blank line
1. Subject is limited to 50 characters (not including Jira issue reference)
1. Subject does not end with a period
1. Subject uses the imperative mood ("add", not "adding")
1. Body wraps at 72 characters
1. Body explains "what" and "why", not "how"
### Documentation
- [x] In case of new functionality, my PR adds documentation that describes
how to use it.
- All the public functions and the classes in the PR contain docstrings
that explain what it does
- If you implement backwards incompatible changes, please leave a note in
the [Updating.md](https://github.com/apache/airflow/blob/master/UPDATING.md) so
we can assign it to a appropriate release
- No documentation needed

> 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
>
> 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
