What happens if a node has a failed Data Engine while rendering a view?

When a node encounters a failure in the Data Engine while rendering a view, the rendering process cannot complete successfully. The Data Engine is responsible for retrieving, processing, and delivering data to be displayed in the view. If it fails, the necessary data cannot be obtained or processed, resulting in a failure of the rendering operation.

This situation is critical because it signifies that the visualizations and insights, which depend on accurate and timely data retrieval, would not be available. The failure prevents the completion of the rendering process, making it impossible for the user to see the expected outcome from the view.

In contrast, other mentioned outcomes would imply either a certain level of redundancy or data retrieval capability that is not present in this scenario, such as falling back on another node or utilizing cached data from an older session. However, without the operational Data Engine on the current node, rendering simply cannot proceed.
