Building a gRPC Service in Golang: Server Streaming RPC (Tutorial)
Welcome to this gRPC video using Golang, part of the series about API Technologies in System Design. In this episode I share with you how to implement a gPRC Service, specifically a Server Streaming RPC using Golang.
== gRPC: Server Streaming RPC?
When building a Server streaming RPCs a client sends a request to the server and gets a stream to read a sequence of messages back. The client reads from the returned stream until there are no more messages. gRPC guarantees message ordering within an individual RPC call.
In practice to do this there are 4 steps:
■ Implement the Service using gRPC via Protocol Buffers
■ Generate the code needed for the actual gRPC Streaming Server RPC
■ Use the generated code to implement the gRPC Streaming Server RPC
■ Use the generated code to interact with the gRPC Streaming Server RPC
== Service kinds in gRPC
There are four kinds of service methods:
■ Unary RPC: https://youtu.be/GgR4JDVgPOc
■ Server Streaming RPC: https://youtu.be/l_74x_qQZB8
■ Client Streaming RPC: https://youtu.be/wKkaCxdfEh8
■ Bidirectional Streaming RPC: https://youtu.be/Z9SHd1K1k5Y
