implements TaskQueue<java.lang.Runnable>

MemoryLimitedTaskQueue in the ShenyuThreadPoolExecutor. It offer a task if the executor's submittedTaskCount less than currentPoolThreadSize or the currentPoolThreadSize more than executor's maximumPoolSize. That can make the executor create new worker when the task num is bigger than corePoolSize but less than maximumPoolSize.
