Description

Although some threads are produced by a ThreadPool, they are not assigned to a separate ThreadGroup, so all threads in IoTDB currently belong to the same default ThreadGroup.

It is advisable to group threads the are produced from the same ThreadPool or have similar functionality. The merit may be seen in monitoring and profiling, where we can choose to focus on a certain ThreadGroup instead of going over all threads.
