我创建了一个lambda函数,该函数从S3下载数据,然后执行合并,然后将数据重新上传回S3,但我得到了这个结果
错误{ “错误消息”:“2020-05-18T23:23:27.556Z 37233f48-18ea-43eb-9030-3e8a2bf62048任务在3.00秒后超时” }
当我删除45和58之间的行时,它工作得很好
作为pd进口熊猫 将numpy作为np导入 导入时间 从io导入StringIO#python3;Python2:BytesIO 进口boto3 导入S3F 从botocore.exceptions导入NoCredentialsError

您应该增加lambda函数的超时时间。新创建函数的默认行为是在3秒后终止
谢谢大家的帮助,只是增加了暂停时间,效果很好,我在这里完成了
您的默认lambda execution timeout为3秒。请将其增加到适合您的任务:
