> When we submit spark core tasks frequently, the submitted node will have a lot of resource pressure, because spark will create a process instead of a thread for each submitted task. In fact, there is a lot of resource consumption. When the QPS of the submitted task is very high, the submission will fail due to insufficient resources. I would like to ask how to optimize the amount of resources consumed by spark core submission
