Project Workflow

Here, i have used a buffered queue to process the requests in parallel.

• Dispatcher: It will initialize the JobQueue and Worker Pool based on the settings.
• Worker: Dispatcher will assign the task to worker and worker will process the task and call handler function.

    Job Queue(Buffered)
    =================================
    |<-Job1->| |<-Job2->| |<-Job3->|
    =================================
                  
              ----------
            ├ Dispatcher ├ ---> Pulls job from Job Queue and assign Job to Worker
             ------------
                
    WorkPool Queue(Channel over channel)
    =========================================
    |<-Worker1->| |<-worker2->| |<-worker3->|
