是的。
但是不管怎么滚动，最终都是checkpoint完成后文件才可见

Re: flink1.11 run
hi、
对于下面这两个的滚动方式，是选优先到达的吗，就是1min的checkpoint和128mb的file size，不管哪个先到都会滚动生成新的文件
》可以，默认下 128MB 滚动，Checkpoint 滚动

Re: flink1.11 run
hi
好的，想问一下stream写hive表的时候：
1、一定要在flink内部先建立hive表吗？
2、如果直接写hive内（hue建表）已经建好的hive表可以吗，文件会有滚动策略吗

hi，我这面请一个一个kafka到hive的程序，但程序无法运行，请问什么原因：
异常：
The program finished with the following exception:

caused an error: No operators defined in streaming topology. Cannot
generate StreamGraph.
