Does GaussDB(DWS) Support a Single Node for a Learning Environment?

Yes. In GaussDB(DWS), you can create a hybrid data warehouse cluster in standalone mode. If the name of the selected node flavor contains h1 (for example, dwsx2.h1.xlarge.2.c6), the hybrid data warehouse only supports standalone deployment, which does not provide HA capabilities. The storage cost can be reduced by half. A standalone data warehouse can be restored by the automatic reconstruction of ECS, and its data reliability is ensured by the EVS multi-copy mechanism. It is less expensive than other specifications. It is a good choice for lightweight services.
