Qlik Sense Nodes
Nodes are the building blocks of Qlik Sense deployment. Each node is a logical or physical machine that hosts one or more services responsible for specific functions.
There are three primary types of nodes based on the services they provide:
- Scheduler Node: Responsible for managing app reloads and service scheduling. This node ensures that data refreshes happen on time, maintaining up-to-date information for users.
- User/Consumer Node: Delivers apps and dashboards to end-users. This node handles user requests and manages interactive sessions.
- Proxy Node: Manages load balancing, session handling, and authentication. It acts as an intermediary between users and the backend services, distributing requests efficiently.
A node can have one or more of these roles depending on the deployment scenario. For example, in smaller deployments, a single node may perform all roles, whereas in large-scale systems, roles are distributed across multiple nodes to improve performance and scalability.
Each node operates independently but communicates with other nodes as part of the overall system. This distributed nature allows Qlik Sense to scale horizontally, handling increased workloads by adding more nodes.
Qlik Sense Sites
