Which single-threaded process accepts requests from various components in a Tableau Server cluster?

The Cache Server is responsible for optimizing performance and managing the storage of commonly accessed data and visualizations within Tableau Server. It acts as an intermediary layer that stores results of queries, which allows for quick retrieval by various components of the server. By handling requests from different parts of a Tableau Server cluster, such as the web application or the VizQL server, the Cache Server significantly reduces the load and enhances response times.

It's important to note that while other components in Tableau Server have specific functions, such as managing data refreshes or analyzing performance metrics, they do not primarily focus on accepting and managing requests across the cluster in the same way the Cache Server does. This dedicated role of handling requests effectively positions the Cache Server as a crucial component in ensuring efficient data retrieval and processing across the entire Tableau Server.
