This feature supports passing user-defined data types (UDTs) and complex data types (CDTs) metadata and values to table operators written in C/C++ and Java. By default, UDT and CDT data values are passed in their transformed form to the table operator. The transformed form is a predefined data type that a UDT or CDT value is converted to by invoking the default transform function defined for the UDT or CDT.

An option is also provided that allows a table operator to request structured UDT, Period, and ARRAY values to be sent and received in an untransformed (atomized) form.

Benefits

UDT and CDT data values can be passed to C/C++ and Java table operators in transformed or untransformed form along with the metadata information.
