Could you give me a example??3Q. ????????????????????????
By the way, I have more than 100 tasks in one DAG. These tasks connect two other server to execute. So SSH tasks must have pool to manager. Now I use JSch and realize a simple pool. ??????????????????????????????????100???? SSH ?????????????????????????????????????????????????? SSH ??????????????????????????????????????????????????

The file contains different modules, some of which are interdependent and some of which are not. When customers purchase different modules, we need to set some tasks as dummy tasks, which some modules are not purchased and the purchased module is not dependent. Because of this setting, these dummy tasks are actually not executed. The benefits of this setup are product unity and diagram integrity. In airflow, these task execute by dummy operator. > > ** Realize ????????** > > Dummy Task ???????????????????????????????????????????????????????????????? dummy ??????????????????????????
