> Is it considered an error if the adaptive scheduler fails to release the task manager during scaling?
+1 . When we enable adaptive mode and perform scaling operations on tasks, a significant part of the goal is to reduce resource usage for the tasks. However, due to some logic in the adaptive scheduler's scheduling process, the task manager cannot be released, and the ultimate goal cannot be achieved. Therefore, I consider this to be a mistake. Additionally, many tasks are currently running in this mode and will continue to run for quite a long time (many users are in this situation). So whether or not it is considered a bug, I believe we need to fix it in the 1.x version.
