Just search for ephemeral in the document and you will hit this: The model foresees control-plane datastores that are by definition not part of the persistent configuration of a device. In some contexts, these have been termed ephemeral datastores since the information is ephemeral, i.e., lost upon reboot. The control-plane datastores interact with the rest of the system through the <applied> or <operational-state> datastores, depending on the type of data they contain. Note that the ephemeral datastore discussed in I2RS documents maps to a control-plane datastore in the revised datastore model described here.
