gRPC [Java] Master Class: Build Modern API and Microservices - What's a Unary API?

The video tutorial explains the concept of a GRPC unary API call, which is a basic request-response model familiar to most developers. It highlights the simplicity and efficiency of unary RPC calls, especially for small data exchanges. The tutorial recommends starting with unary RPC when developing APIs and only considering streaming APIs for specific performance improvements. It also covers the use of protocol buffers to define request and response messages, providing a foundation for implementing unary RPC in applications.
