Previously, we have demonstrated how to implement a bi-directional gRPC streaming server using python. Once the server implementation is ready we will implement the client. In order to implement the client we will have to use the same proto file as the server as that acts as a data contract between server and client. Proto file as follows.
So today we will demonstrate how to setup a bi-directional server using python & gRPC. The very first step to setup any gRPC streaming is to create a data contract in the form of a protocol buffer file. In our demonstration, we will use a simple contract that should be able to create some resource entries to the server in the stream and expect a response in the form of a stream.
A proto file is a schema definition about your messages and your structured data. This proto file will need to be converted to X language file. Google has built a compiler called protoC, to this you will need to feed it, what language you want the output to be, and it will output that equivalent language. If you give javascript, the protoC will give you a javascript equivalent file, in case you give it a python, it will give you a python file with the same schema. That is why it is language neutral.
