kaxil commented on issue #6715: [AIRFLOW-5945] Make inbuilt OperatorLinks work when using Serialization URL: https://github.com/apache/airflow/pull/6715#issuecomment-560795290 > What do you think to save the generated links in a separate column in the database after Task execution? I think it will be nicer because it will not be storing additional partial data, but the final data that interests us. This could be realized independent of DAG serialization. In addition, it will simplify the logic of handling these links. Now it is not possible to download all links for a given task, but we download one link in one HTTP request. https://github.com/apache/airflow/blob/master/airflow/www/templates/airflow/dag.html#L492-L518 This is actually the 1st solution I mentioned to Ash and I thought it was the way to go :) Unfortunately Ash mentioned a use-case that ruled it out which was I think "S3 signed URL can have an expiration date of 15 mins and change after that". @ashb can probably explain that in more detail but due to that use-case storing the links in DB wouldn't work.
