11.10. Interoperability Between Hot Rod C++ and Hot Rod Java Client

Red Hat JBoss Data Grid provides interoperability between Hot Rod Java and Hot Rod C++ clients to access structured data. This is made possible by structuring and serializing data using Google's Protobuf format.

For example, using interoperability between languages would allow a Hot Rod C++ client to write the following Person object structured and serialized using Protobuf, and the Hot Rod Java client can read the same Person object structured as Protobuf.

package sample;
message Person {
    required int32 age = 1;
    required string name = 2;
}

Interoperability between C++ and Hot Rod Java Client is fully supported for primitive data types, strings, and byte arrays, as Protobuf and Protostream are not required for these types of interoperability.
