In this talk, we describe how we moved backing watson discovery microservices from rest to grpc and the lessons we learned in the process.
It includes libprotobufc, a pure c library that implements protobuf encoding and decoding, and protocc, a code generator that converts protocol buffer. Youll find there are a couple of different implementations, many of which are designed for inclusion in different frameworks, such as service stack. The backend has the client management, financial product, portfolio tracking, and reporting services to provide a full range of financial inclusion. Type is not expected, and no contract can be inferred with. By walking through creating a simple example application, it shows you how to. The method involves an interface description language that describes the structure of some data and a program that generates source code from that description for generating or parsing a stream of bytes that represents the. A question came up on stack overflow yesterday which ive had to deal with myself before now. Since protocol buffers is a binary format, protobuf net is based heavily around the stream class. An option can be a protobuf defined option or a custom option. If the raw net performance is the target, then nothing beats iiop. This template could be useful as a simple ipc communication scheme where the. Any contains an arbitrary serialized protocol buffer message along with a url that describes the type of the serialized message summary.
In our earlier example, the binary data generated from our class. Unlike messages where we generate a structure that corresponds to the actual message object, for services we generate a function that creates a protobufcservice from a collection of userdefined methods we also define simple functions that invoke each. Added an example of the use and the unit tests for this example. Options can be used in proto files, messages, enums and services. Indeed, this came up in protocol buffers at least once, i believe.
