Job authoring with data preview

Jobs can be authored in conjunction with a visual workspace. Upon selection of representation of a data source in the workspace, a preview of the data source can be generated within context of the visual workspace. Further, representations of one or more data transformation operations can be provided with the preview. Selection of a transformation operation results in an updated preview reflecting application of the operation as well as generation of backend code to perform the operation. Furthermore, a job comprising one or more transformation operations can be added to the workspace automatically. 可以结合视觉工作空间创建作业。在选择工作空间的数据源的表示时，数据源的预览可以在视觉工作空间的上下文内被生成。此外，个或多个数据转换操作的表示可以被提供有预览。转换操作的选择导致反映操作的应用的更新预览以及执行操作的后端代码的生成。另外，包括个或多个转换操作的作业可以被自动地添加到工作空间。
