dn_default_space_usage_thresholds | 0.85 | 定义每个层级数据目录的最大使用空间比例；当使用空间大于该比例时，数据会被自动迁移至下一个层级；当最后一个层级的使用存储空间大于此阈值时，会将系统置为 READ_ONLY | 每级存储使用分号分隔；层级数量需与 dn_data_dirs 定义的层级数一致 | | object_storage_type | AWS_S3 | 云端存储类型 | IoTDB 支持 S3 协议作为远端存储类型 | | object_storage_bucket | iotdb_data | 云端存储 bucket 的名称 | AWS S3 中的 bucket 定义；如果未使用远端存储，无需配置 | | object_storage_region | | 云端存储的服务区域 | AWS S3 中的 region 定义；如果未使用远端存储，无需配置 |
