What are the effects of a Cache Server process failure?

When a Cache Server process fails, the most relevant effect is that actions will still be processed, but they may take longer than usual. This is because while the Cache Server plays a critical role in enhancing performance by storing frequently accessed data, its failure doesn't halt all operations. Tableau Server can still retrieve the necessary data; however, this retrieval will likely have to be done directly from the data source rather than from the cache, which results in slower performance due to the additional overhead of querying the underlying data sources.

In cases of a Cache Server failure, Tableau Server maintains its functionality, but users might experience a noticeable increase in the time it takes to execute queries and deliver visualizations, as the optimized paths offered by cached data are no longer available. This response demonstrates the resilience of Tableau Server architecture, which allows for ongoing operations even in the face of a Cache Server issue.
