Which type of data store is utilized to store caches for hosted scene layers?

Hosted scene layers in a 3D environment require efficient access to rendering data, and that's where the Tile Cache data store comes into play. This type of data store is specifically designed to manage tiles, which are essentially pre-rendered and optimized views of spatial data. When it comes to visualizing large datasets, particularly in a hosted environment, tile caches significantly improve performance by enabling quick access to regions of interest without needing to load entire datasets.

Tile caches are structured to support the hierarchical storage of tiles, allowing for multiple levels of detail. This structure benefits rendering applications that need to display data at varying zoom levels efficiently. Thus, when a user interacts with a 3D scene, the application can dynamically request the appropriate tiles from the cache that are relevant to the current view, rather than re-processing the raw data every time.

In contrast, other data stores like relational or file-based might not be optimized for the specific storage and retrieval needs of cached tiles, which are vital for delivering smooth and responsive 3D visualizations. Spatiotemporal big data stores can handle time-based and spatial queries well but are not tailored for the caching needs of hosted scene layers. Therefore, the use of a Tile Cache data store is essential for the efficient functioning of
