[Filters] Add task-level filters to DAG View - Graph tab

[cmarteepants]

View

DAG View - Graph Tab

Filters to Add

• Filter by Task Group
  ↪ Useful for narrowing view to a specific section of a large DAG

• Filter by Operator
  ↪ Helps identify all tasks of a certain type (e.g., BashOperator vs. PythonOperator) within the DAG

When looking at graph for specific Dag Run:

• Filter by Task Status (Success, Failed, Skipped, etc.) when looking at graph for specific dag run
  ↪ Helps users focus on problematic tasks or ignore successful ones in complex DAGs

• Filter by Mapped Index (for mapped tasks) when looking at graph for a specific dag run
  ↪ Supports debugging of specific mapped task instances when hundreds exist

• Filter by Duration Threshold
  ↪ Highlight long-running tasks for performance triage or resource bottlenecks

API Support

❌ No

• The Graph View uses the DAG structure and DAG Run state but does not currently expose API query parameters for task-level filtering.
• Data exists in task instances API but is not integrated here.

UI Impact

• Filters could appear above the DAG Graph or in a collapsible sidebar.
• Task nodes would update based on filter selection; unmatching nodes could be dimmed or hidden.

Notes

• Particularly valuable for large DAGs with many tasks and/or dynamic mapping
• Could integrate with color coding to enhance visibility of filter results

I want to work on it. Assign it to me.

@muhammadhaseebiqbal-dev did you get a chance to work on this? This is required for 3.1.0 release

[phanikumv]

Reassigning to @vatsrahul1001 as we need this for 3.1.0

[dylanschw]

Is this free to work on?

[pierrejeambrun]

Unassigning @vatsrahul1001 to let the opportunity for others to work on it.

@dylanschw please go ahead I'd be glad to review a PR in that sense.
