What is the impact of a Cache Server process failure on Tableau Server?

When a Cache Server process fails on Tableau Server, it affects the overall performance of the Server. The Cache Server is responsible for storing the results of queries, which allows for faster retrieval when the same queries are made again. If this process fails, Tableau Server will no longer have access to cached results, leading to a situation where all actions that depend on querying data will take longer as they must fetch data directly from the data source instead of retrieving it from the cache.

The absence of cached data means that the response times for visualizations and dashboards will increase, resulting in a slower experience for users analyzing data. This slowdown will impact all types of interactions with the Tableau Server that depend on querying forms of data.

While it may not cause the entire server to crash or exclusively delay report generation, the overall user experience becomes noticeable due to the increased response times across various operations. Thus, the correct understanding of the result of a Cache Server process failure emphasizes the impact on performance, leading to longer processing times for all actions.
