### Description The S3Hook registers an output asset for every file which it uploads: https://github.com/apache/airflow/blob/e491aac92a1d50f322a08d92d83616e7c79b3f2e/providers/amazon/src/airflow/providers/amazon/aws/hooks/s3.py#L1376-L1379 Which is not always the desired behaviour when using the S3 Hook (see motivating example below). I'd propose just adding a switch to the S3Hook so disable this sort of lineage: ```python hook = S3Hook(enable_hook_level_lineage=False) ``` I am happy to submit a fix here, but I wanted to run it by y'all first to make sure that I'm not missing some previous context or undoing an intentional design decision. ### Use case/motivation We have seen issues where users upload chunked data to S3 within a PythonOperator like so: ```python hook = S3Hook() for idx, data in enumerate(list_of_values): hook.upload_string(data, f"some_prefix/file_{idx}.txt", "some_bucket") ``` Which then creates a _ton_ of output assets. I know that this is limited to 100 output objects (since https://github.com/apache/airflow/pull/45798), but it would be nice if we could disable hook-level lineage altogether and instead manage our own output asset definition at the custom operator / PythonOperator level. In this case, we likely want to only enable a single output asset at the `some_prefix/` level, not one per file. This likely applies to other object storage hooks as well. ### 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)
