我正在使用 AWS Kinesis Firehose 流来摄取数据,然后使用 lambda 函数在写入 S3 存储桶之前进行架构验证和数据转换。我之前一直将不正确记录的状态设置为 ProcessingFailed 并将这些错误写入{stream_id}/errors/{timestamp}/processing-failed文件夹,但该方法会写入自动生成的错误响应:

{
    "attemptsMade": "1",
    "arrivalTimestamp": "timestamp",
    "errorCode": "Lambda.ProcessingFailedStatus",
    "errorMessage": "ProcessingFailed status set for record",
    "attemptEndingTimestamp": "timestamp",
    "rawData": "data example",
    "lambdaArn": "arn"
}

是否可以创建一个自定义错误输出类型,该类型将写入{stream_id}/errors/{timestamp}/custom-error,带有自定义错误消息和看起来更像这样的字段?

{
    "errorCode": "ValidationFailedStatus",
    "errorMessage": "Validation failed because 'state' was not present in data"
}

我想另一种选择是使用动态分区。
