| Key | Type | Required | Default | Description |

| ------------------------- | --------------------------------------------------------------------- | -------- | ----------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |

| name | String | Yes | None | Bucket name in S3 provider |

| prefix | String | No | None | Bucket prefix |

| region | String | No | `us-east-1` | Bucket region |

| s3Endpoint | String | No | None | Custom S3 Endpoint for non AWS S3 bucket |

| credentials | [BucketCredentialConfiguration](#bucketcredentialconfiguration) | No | None | Credentials to access S3 bucket |

| disableSSL | Boolean | No | `false` | Disable SSL connection |

| s3ListMaxKeys | Integer | No | `1000` | This flag will be used for the max pagination list management of files and "folders" in S3. In S3 list requests, the limit is fixed to 1000 items maximum. S3-Proxy will allow to increase this by making multiple requests to S3. Warning: This will increase the memory and CPU usage. |

| requestConfig | [BucketRequestConfigConfiguration](#bucketrequestconfigconfiguration) | No | `nil` | This will allow to customize requests sent to your S3 backend. |

| s3MaxUploadParts | Integer | No | `10000` | MaxUploadParts is the max number of parts which will be uploaded to S3. |

| s3UploadPartSize | Integer | No | `5` | The buffer size (in megabytes) to use when buffering data into chunks and sending them as parts to S3. The minimum allowed part size is 5MB, and if this value is set to zero, the DefaultUploadPartSize value will be used. |

| s3UploadConcurrency | Integer | No | `5` | The number of goroutines to spin up in parallel per call to Upload when sending parts. If this is set to zero, the DefaultUploadConcurrency value will be used. |

| s3UploadLeavePartsOnError | Boolean | No | `false` | Setting this value to true will cause the SDK to avoid calling AbortMultipartUpload on a failure, leaving all successfully uploaded parts on S3 for manual recovery. |
