Do you avoid things like task sensors? Based off what you described it sounds like an anti pattern if you’re using them.

Great description of good orchestration design. Airflow is fairly open ended in how you can construct dags, leading to some interesting results.

Yes, I think you could make an argument for them, but in general it means putting your state sensing into orchestration (local truth) rather than something external (universal truth). As with anything, it does depend on your application though. If you were running something like an ETL, I think it’s generally more appropriate to sense the output of that ETL (data artifact, table, partition, etc) than it is to sense the task itself. It does present some challenges for e.g. cascading backfills, but I think it’s a fine tradeoff in most applications.
