 ## Refresh Modes
 
-Spice supports four modes to refresh/update local data from a connected data source. `full` is the default mode.

 Datasets configured with acceleration `refresh_mode: changes` requires a [Change Data Capture (CDC)](/docs/features/cdc/index.md) supported data connector. Initial CDC support in Spice is supported by the [Debezium data connector](/docs/components/data-connectors/debezium.md).
 
-### Caching
-
-The `caching` refresh mode is designed for HTTP-based datasets where request metadata acts as cache keys. This mode is particularly useful for API responses that return multiple rows for a single request, such as search results or dynamic content endpoints.
