DAG Scheduler Pattern

DAG is Directed Acyclic Graph scheduling pattern is used when we need things to be processed in parallel with the control of which tasks go first which tasks go second or which tasks are grouped together.

And you also have a control over of the worker (some is powerful, some is not) and assign the task respectively for each one

This might have more benefits than a Alexu System Design Interview/1. Scale from zero to millions of users/Message queue system.

Take in the DAG Config files and prioritise it:

Resource Manager

From the task we can manually select the optimal worker for that task and save the resource of redundant worker hanging as part of a Resource manager
