In some scenarios, tens of thousands of consumers may be started in one instance, and the traffic of most consumers is very low or even non-existent. These consumers each have their own independent thread pool, causing the JVM to create tens of thousands of threads, seriously affecting performance. Therefore, I have an idea. Can we allow different consumers to reuse the thread pool for this scenario, reduce system resource consumption and improve performance? ### Brief Description <!-- Write a brief description for your pull request to help the maintainer understand the reasons behind your changes. --> ### How Did You Test This Change? <!-- In order to ensure the code quality of Apache RocketMQ, we expect every pull request to have undergone thorough testing. --> -- This is an automated message from the Apache Git Service.
