Description

Description

We use private staging and prod S3s(Ceph clusters for example) in our office. So there are often cases where DAGs are running with only connection ids changed. We prefer to use Param rather than to use hardcoded connection ids to make our code reusable. I only gave an example for Amazon operator, but templating connection ids is required for other operators too.

Why is it needed? Code reusability

Use case/motivation

with DAG(
    dag_id="example_s3",
    params={
        "aws_conn_id": Param("", type="string"),
    },
    ...
) as dag:

    create_object = S3CreateObjectOperator(
        task_id="create_object",
        s3_bucket=bucket_name,
        s3_key=key,
        data=DATA,
        replace=True,
        aws_conn_id="{{ params.aws_conn_id }}", # Params enable us to provide runtime configuration
    )
