 | log\_key                         | By default, the whole log record will be sent to S3. If you specify a key name with this option, then only the value of that key will be sent to S3. For example, if you are using Docker, you can specify log\_key log and only the log message will be sent to S3.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      | None                                    |
 | preserve\_data\_ordering         | Normally, when an upload request fails, there is a high chance for the last received chunk to be swapped with a later chunk, resulting in data shuffling. This feature prevents this shuffling by using a queue logic for uploads.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        | false                                   |
