scm dispatch

A dispatch group allows an organization thread to know that one or more tasks are completed. If you have a scenario where the main thread should not continue to run until the task in the queue is finished, you can use dispatch group technology to have one or more queues wait for the execution to complete before returning to the main thread. The following example shows the basic usage of creating a

Let's understand it literally. intuitively, it refers to two dispatches. What does dispatch mean here? For example: Class Event{ Public : Virtual Void Printname (){Cout " I am a general event " Endl;}} Class Keyevent: Public Event{ Public : Virtual Void Printname (){Cout " I am a key event " Endl;}} Class Clickevent: Public Event{ Public : Virtual Void Printname (){Cout " Click events " Endl;}}

PurposeThis document describes a pluggable FairScheduler scheduler for Hadoop, agreeing that YARN applications share resources fairly in a large cluster.Simple IntroductionFair scheduling is a method of allocating resources to applications. So that in the end, all applications on average get equal resources. Hadoop NextGen can dispatch multiple types of resources. By default, Fair Scheduler only makes a fair scheduling decision based on memory. The me

Abstract state machine class QFSM or QHSM has a function pointer that points to the specific state function in the inherited state machine class, which has two interface function init () and dispatch (), which works by understanding the key of the state machine handling event process.The State machine class inherits from QFSM or QHSM, and inherits this function pointer, which is used to dynamically point to the private state function in the specific s

In many cases, it is necessary to use timed scheduling, such as running a crawler at regular intervals to crawl new data, with quartz,spring task and timerSpring Task can compare it to a lightweight quartz, and it is simple to use, except that there is no need for additional packages outside of spring-related packagesRecommended use of annotation-style implementationsImport Org.springframework.scheduling.annotation.scheduled;import org.springframework.stereotype.component;@ Componentpublic class

Bank Business Dispatch system First, the need to simulate the implementation of banking business scheduling system logic, the specific requirements are as follows: 1. There are 6 business windows in the Bank, 1-4 window is the normal window, window 5th is the Quick window, and the 6th window is the VIP window. 2. There are three types of customers: VIP customers, ordinary customers, fast customers (handling such as electricity and water bills, such as
