With C++ Apache Thrift library, is it possible to use only Serialization/Deserialization and not use RPC services?

As I understand from this page, it is possible to do with Java library. However, I could not find the similar classes for C++ library.

Yes it is possible. Thrift lacks documentation about this subject. Well, about anything really.

Here i found this:

i personally use boost::serialization if there is no need to transfer data over network. Much clear syntax and supports JSON, XML and binary output/input.

In c++ you can use the TFileTransport:

boost::shared_ptr<TFileTransport> transport(new TFileTransport(filename));
boost::shared_ptr<TBinaryProtocol> protocol(new TBinaryProtocol(transport));
yourObj.write(protocol.get()); // to write

or

yourObj.read(protocol.get()); // to read

If you simply want to serialize into bytes (without having to write to a file), you can use TMemoryBuffer.

boost::shared_ptr<TMemoryBuffer> buffer(new TMemoryBuffer());
boost::shared_ptr<TBinaryProtocol> binaryProtcol(new TBinaryProtocol(buffer));

obj->write(binaryProtcol.get());
obj->read((binaryProtcol.get()));

Here's a different mailing list post with some attached code showing how to use thrift to serialize to a file in C++.

I realize that this question was asked a while ago. I encountered a similar use case recently (with an additional requirement - sending the serialized bytes to a Kafka cluster). Here's my answer with more complete code snippets that illustrate how the serialization and sending tasks can be done.
