AWS Lambda常見問題_Lambda是什麼意思

問:如果賬戶超出併發執行預設限制數量會怎麼樣?

如果超出限制,同步呼叫的 AWS Lambda 函式會返回一條節流錯誤資訊 (429 錯誤程式碼)。非同步呼叫的 Lambda 函式可以承受一定範圍內的流量突增大約 15 到 30 分鐘,之後再進來的事件將會以節流為理由遭到拒絕。如果呼叫的 Lambda 函式是用於響應 Amazon S3 事件,則被 AWS Lambda 拒絕的事件可能被 S3 保留 24 小時並在此期間反覆重試。Amazon Kinesis 流和 Amazon DynamoDB 流中的事件會反覆重試,直到 Lambda 函式成功或資料過期。Amazon Kinesis 和 Amazon DynamoDB 流會將資料保留 24 小時。
