Chapter 7: Running gRPC in Production

ProductInfo Service and Client

• Online retail scenario has a ProductInfo microservice which is responsible for managing the products and their information. The consumer of that service can add, retrieve products via that service.

• ProductInfo service and the consumer of that service are implemented in both Go and Java languages.

• This use case shows how you can implement both ProductInfo service and its consumer.

Service Definition

package ecommerce;

service ProductInfo {
    rpc addProduct(Product) returns (ProductID);
    rpc getProduct(ProductID) returns (Product);

    string name = 2;
    string description = 3;
    float price = 4;
}

message ProductID {
    string value = 1;
}
