What occurs if the VizQL Server process fails?

When the VizQL Server process fails, it is crucial to understand the role of this process within Tableau Server. The VizQL Server is responsible for rendering visualizations and processing queries generated by the clients. If the server only has a single VizQL Server process running and that process fails, there will be no active instance left to handle visualization requests. Consequently, views will become unrenderable, leading to an interruption in the rendering of visualizations.

In environments with multiple VizQL Server processes, failover capabilities may exist, allowing other processes to take over and continue serving requests. However, if only one instance is present, the failure directly impacts the ability to render views, making it essential to have a redundant configuration for higher availability in production environments. Thus, the correct answer highlights the dependency on the VizQL Server process and the critical nature of redundancy.
