You can install it as follows: pip install apache-airflow==1.10.13rc1 Regards, Kaxil On Tue, Nov 24, 2020 at 3:57 AM lunbingli <[email protected]> wrote: Recently I have my airflow upgraded from 1.10.10 to 1.10.12 and find my dags are scheduled much slower than before. One of my dag is as follows（please check attachment） and it has 400 Tasks of DummyOperator. It took only 4+mins with 1.10.10 while it took more than 16mins with 1.10.12. Can someone tell me what the problem may be？I tried to compare the code diff between these two versions with https://github.com/apache/airflow/compare/1.10.10...1.10.12 and failed to draw a conclusion yet.
