 | compression                      | Compression type for S3 objects. 'gzip' is currently the only supported value by default. If Apache Arrow support was enabled at compile time, you can also use 'arrow'. For gzip compression, the Content-Encoding HTTP Header will be set to 'gzip'. Gzip compression can be enabled when `use_put_object` is 'on' or 'off' (PutObject and Multipart). Arrow compression can only be enabled with `use_put_object On`.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         | None                                    |
+| server\_side\_encryption         | Server-side encryption scheme to use.  'AES256' or 'aws:kms' [are the only supported values](https://docs.aws.amazon.com/AmazonS3/latest/API/API_PutObject.html#API_PutObject_ResponseSyntax).  No server-side encryption is the default.
 | content\_type                    | A standard MIME type for the S3 object; this will be set as the Content-Type HTTP header.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        | None                                    |

 | auto\_retry\_requests            | Immediately retry failed requests to AWS services once. This option does not affect the normal Fluent Bit retry mechanism with backoff.
