"jdbc:vertica://BadVerticaHost:5433/vmart", myProp) MyProp.put("BackupServerNode", "VerticaHost02,VerticaHost03") The following is a JDBC sample code, with Load balance and Fail over enabled. Query the Load balance policy on the server side SELECT SET_LOAD_BALANCE_POLICY('ROUNDROBIN') The specific setting code is: -The method of setting node load balance, there are three types: NONE/ROUNDROBIN/RANDOM NONE is to disable load balancing, ROUNDROBIN is polling, and RANDOM is random, which is recommended.
