In the above example, JDBC uses the client's configuration file to establish a connection to a hostname `cluster_node1`, port 6030, and a database named `test`. When the firstEp node in the cluster fails, JDBC attempts to connect to the cluster using secondEp. In the above example, JDBC uses the client's configuration file to establish a connection to a hostname `cluster_node1`, port 6030, and a database named `test`.

In TDengine, as long as one node in firstEp and secondEp is valid, the connection to the cluster can be established normally. In TDengine, as long as one node in firstEp and secondEp is valid, the connection to the cluster can be established normally.
