Client Streaming RPC in FTP Service
Understand how to implement client streaming RPC in gRPC to efficiently upload files by sending a stream of messages from client to server. Explore service definitions, server and client code, and asynchronous communication using StreamObserver in Java.
Client streaming RPC is one of the four types of RPC (Remote Procedure Call) in gRPC, where the client sends a stream of messages to the server and then receives a single response from the server. This type of RPC is useful when the client needs to send a large amount of data to the server without waiting for a response after each message. The client opens a channel to the server and then sends messages continuously. The server handles the stream of messages and then returns a response.
Overview
In the ftp_service.proto file, we define the addFile RPC which contains the business logic to add a file. The client opens a channel and sends a request ...
