I have been designing the multi-node deployment of QlikSense.
QlikSense manual depicts several design patterns of scheduler node.
Usually, QES and QSD must run on all nodes.
But when it comes to the scheduler node, an example has QRS + QES + QSS. Other example has QRS + QSD + QSS
Situation is like this:
|Repo Serv. (QRS)||Service Disp. (QSD)||Engine (QES)||Scheduler (QSS)|
What is the essential services we need to run on the scheduler node?
I should appreciate for your advices in advance.
