+## Data Refresh
+
+Dataset acceleration can be configured in `full` (the entire dataset is refreshed) or `append` (new data from a dataset source is appended) acceleration modes.
+
+The data refresh interval for an accelerated dataset in `full` mode can be specified via [refresh_interval](/reference/spicepod/datasets#accelerationrefresh_interval) or triggered via Api (`POST`, `/v1/datasets/:name/refresh`).
+
+An example CuRL
