The other solution will be (as you suggested) to create a fetch request for each entity.
另一个解决方案将是(如您所建议)为每个实体创建一个抓取请求。
When results of a query are sent back to a requesting application, they can be sent a-row-at-a-time every time a requesting application issues a FETCH request.
在将查询的结果发送回发出请求的应用程序之后，每当应用程序发出FETCH请求时，可以将结果逐行返回。
