AWS托管的Apache Airflow（MWAA）服务中，默认情况下有1个工作人员和1个调度器。您可以通过以下代码示例来获取这些默认值：

import boto3

# 创建MWAA客户端
client = boto3.client('mwaa')

# 获取MWAA环境的默认工作人员和调度器数量
response = client.describe_environment(
    Name='your-mwaa-environment-name'
)

worker_count = response['Environment']['ExecutionRoleArn']
scheduler_count = response['Environment']['Scheduler']['InstanceCount']

print(f"Default worker count: {worker_count}")
print(f"Default scheduler count: {scheduler_count}")

请确保替换your-mwaa-environment-name为您实际的MWAA环境名称。运行以上代码将打印出默认的工作人员和调度器数量。
