AardJan opened a new issue, #55133: URL: https://github.com/apache/airflow/issues/55133
### Description Right now in DagRun → Task → Asset Events, we only see: - how many assets a task generated, - first 50 of them. <img width="1542" height="742" alt="Image" src="https://github.com/user-attachments/assets/2edb17ea-5475-4872-9083-4798f029ca9a"; /> That’s pretty limiting. Our users often create tasks with an unknown number of datasets (using datasetalias) — sometimes it’s just 1 asset, sometimes a few thousand. example code: ``` python import os from datetime import datetime from airflow.sdk import DAG, Asset, AssetAlias, get_current_context, Param from airflow.decorators import task from airflow.providers.standard.operators.empty import EmptyOperator DAG_ID = os.path.splitext(os.path.basename(__file__))[0] asset_alias = AssetAlias("test-airflow-3-dataset-alias") with DAG( dag_id=DAG_ID, start_date=datetime(2024, 1, 1), schedule=None, catchup=False, params={ "dataset_qty": Param(1, type="integer", minimum=1), } ) as dag: start = EmptyOperator(task_id="start") @task def build_dataset_list(): ctx = get_current_context() qty = int(ctx["params"].get("dataset_qty", 1)) return [f"example_dataset_{i}" for i in range(1, qty + 1)] @task(outlets=[asset_alias]) def emit(datasets: list[str], outlet_events): for name in datasets: print(f"Emitting logical asset event for: {name} via alias {asset_alias.name}") outlet_events[asset_alias].add(Asset(name)) return datasets end = EmptyOperator(task_id="end") ds_list = build_dataset_list() start >> ds_list >> emit(ds_list) >> end ``` ### Use case/motivation We would like to be able to: - browse all generated assets for a given task with pagination - search/filter them by name ### Related issues _No response_ ### Are you willing to submit a PR? - [x] Yes I am willing to submit a PR! ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://github.com/apache/airflow/blob/main/CODE_OF_CONDUCT.md) -- This is an automated message from the Apache Git Service.
