In which data store type does hosted feature layers created from spatial analysis tools reside?

Hosted feature layers created from spatial analysis tools reside in a relational data store. This type of data store is designed to support the storage and management of structured data, which is essential for hosted feature layers that need to maintain attributes and relationships within the data.

Hosted feature layers benefit from the capabilities of a relational data store, as they allow for efficient querying, editing, and analysis of the data. The underlying architecture supports transactions and ensures data integrity, making it suitable for applications that require precise control over data management.

While other data store types serve specific purposes — like tile caches for serving map tiles, spatiotemporal big data stores for handling large volumes of temporal data, or cache data stores primarily used for fast access to frequently requested data — they are not designed to manage the structured datasets typical of hosted feature layers. Therefore, the relational data store is the appropriate choice for hosted feature layers created from spatial analysis tools.
