安排气流停滞30秒

Question

我对气流还很陌生。我有一个dag文件，希望每30秒对其进行安排。我该怎么做？

from datetime import datetime
from airflow import DAG
from airflow.operators.bash_operator import BashOperator
from airflow.operators.dummy_operator import DummyOperator
from dependency_node import DependencyNode, resolve_dependency_to_edges
import os

FILE_NAME = os.path.basename(__file__).split('.')[0]

default_args = {
  "owner": "airflow",
  "wait_for_downstream": True,
  "start_date": datetime(2019,12,19),
  "retries": 0
}

DAG_ARGS = {
  "schedule_interval": '*/1 * * * *',
  "catchup": False
}

这是我的dag参数的样子，它排定为1分钟，但我想将其排定为30秒。

如果能得到帮助，我将不胜感激
