What is the process called that allows for updates without requiring a server restart?

The process that allows for updates without requiring a server restart is known as Dynamic Topology. This feature enables a server to adjust its configuration and resource allocation dynamically in response to workload changes or system requirements. It enhances system availability and performance by allowing administrators to make changes and updates while the server is running, thereby minimizing downtime and disruption to users.

Dynamic Topology facilitates seamless operation in environments where continuous availability is critical. This capability is particularly important for data visualization and analytics applications that demand high uptime, as it helps ensure that users can access their data and reports without interruptions due to server maintenance or updates.

In contrast, the other options refer to different aspects or components of server management or architecture. Cluster Controller, for example, plays a role in managing and coordinating tasks across a cluster of servers, but it does not specifically address the ability to apply updates without a restart. Elastic Server usually refers to scalability features of servers that can dynamically adjust resources based on demand but does not pertain to update processes. Backgrounder is a service that runs within the Tableau Server architecture to perform scheduled tasks and refresh data extracts, but it is not related to the concept of updating server configurations dynamically.
