+ <title>Kudu Considerations for DML Statements</title>
+ <conbody>
+ <p>
+ Currently, Impala <codeph>INSERT</codeph>, <codeph>UPDATE</codeph>, or
+ other DML statements issued through the JDBC interface against a Kudu
+ table do not return JDBC error codes for conditions such as duplicate
+ primary key columns. Therefore, for applications that issue a high
+ volume of DML statements, prefer to use the Kudu Java API directly
+ rather than a JDBC application.
