             Summary: improve JDBC API getSchema() setSchema() performance
                 Key: TRAFODION-2155
                 URL: https://issues.apache.org/jira/browse/TRAFODION-2155
             Project: Apache Trafodion
          Issue Type: Improvement
            Reporter: liu ming


At present, client invoke JDBC API getSchema/setSchema, the driver must invoke 
SQL command to do the real get/set operation, and that is a full client/server 
communication. It is in fact a way to improve the getSchema, that the driver 
keep the current schema itself, without the need to ask the Server. See 
discussion in TRAFODION-1986
