URL: https://github.com/apache/incubator-dolphinscheduler/issues/4385
*i met a situation that the memory fulls and the dolphinscheduler server
down when i start the recording data(补数) tasks, if there is a feature that we
can configure the parallelism of supplementary recording data manually *
**Describe the question**
The memory fulls and the dolphinscheduler server down when i start the
recording data(补数) tasks.
**What are the current deficiencies and the benefits of improvement**
We can configure the parallelism of supplementary recording data manually so
that the machine resource will not be occupied too much.
**Which version of DolphinScheduler:**
-[1.3.3-preview]
**Describe alternatives you've considered**
Changing the model to "Serial"(串行) but this model will take too much time.
