类 IoTDBThreadPoolFactory

java.lang.Object

org.apache.iotdb.db.concurrent.IoTDBThreadPoolFactory

public class IoTDBThreadPoolFactory
extends Object

This class is used to create thread pool which must contain the pool name. Notice that IoTDB project does not allow creating ThreadPool using Executors.newXXX() function to get a threadpool because it is hard to be traced.
