Can I Import Data over the Public/External Network Using GDS?¶
No. The GDS server and GaussDB(DWS) can only communicate with each other on the intranet. Each DN in the GaussDB(DWS) cluster is used to connect to the GDS server in parallel to import a large amount of data. The GDS server and the cluster must be in the same network. If GDS is deployed on an offline server, the firewall needs to be enabled and the cluster needs an EIP. However, one cluster can be bound only to one EIP, and data import with multiple DNs cannot be implemented.
