def lambda_handler(event, context): This is the main handler function for your code, which contains your main application logic. When Lambda invokes your function handler, the Lambda runtime passes two arguments to the function, the event object that contains data for your function to process ...

When lambda expressions are used with event handlers, you may not see the behavior you expect. The compiler generates a new method for each lambda expression definition, even if they are identical. Therefore, the following code displaysFalse. ...

可以看到,幂等性装饰器配置了一个持久化层,本例中是一个叫作IdempotencyTable的 DynamoDB 表。此外,通过在event_key_jmespath参数中传递id,装饰器知道只使用id属性来创建事件对象的唯一哈希。raise_on_no_idempotency_key设置为True,避免出现事件中缺少id的情况,这种情况是非预期的。
