> In the program, since the number of instances (instances =
> llapRegistryService.getInstances().getAll();) is not known ahead of time, it
> has a high risk in causing OutOfMemoryError when too many threads are
> created. Therefore, to ensure security, a fixed number of thread pool should
> be used, which can be freely configured and also enables running multiple
> instances concurrently but is free from the above error.
