Destination是Lambda函数在异步调用(asynchronous invocation)时可以发送调用记录(invocation records)去的AWS服务。在异步调用中,我们可以配置Lambda函数把调用记录发送到queue,topic,function或者event bus(Cloudwatch event)。 我们可以为成功的调用(invocation)和失败的调用配置不同的Destination。调用记录中包含有event的信息,...

Lambda retries processing the asynchronous invocation event for a maximum of two times, in case of function error or exception. Lambda drops the event from its internal queue if the retries are exhausted. To simulate a function error, throw an exception from the Lambda handler: Edit the function...
在Asynchronous invocation (异步调用)下,选择Edit (编辑)。 将死信队列服务设置为Amazon SQS或Amazon SNS。 选择目标队列或主题。 选择保存。 Lambda 按原样将事件发送到死信队列,并在属性中包含其他信息。您可以使用此信息来标识函数返回的错误,或者将事件与日志或 AWS X-Ray 跟踪相关联。
function receives it (throttling and system errors (400-series and 500-series)). Function errors occur when the function’s code or runtime returns an error (exceptions and timeouts). The Lambda service retries the function invocation if it encounters unhandled errors in an asynchronous invocatio...
Lambda - Asynchronous Invocations How it works? For example, s3 trigger Lambda, it will put events into a Queue, Lambda will read from Queue max 3 times if need retry, then you will see multi logs in CloudWatch. After 3 times retry, will send to DLQ. ...
