> I came across the TODO in airflow/ti_deps/deps/trigger_rule_dep (line 52) that says instead of checking the query for every task let the tasks report to the dagrun. I have a dag with many tasks and the delay between tasks can rise to 10 seconds or more, I already changed the configuration, added processes and memory, checked the code and did research, profiling and other experiments. I hope that this change will make a drastic change in the delay. I would be happy to discuss this solution, the research and other solutions for this issue.
> Thanks
