kv-store-grpc

A gRPC-based key-value store uses protobuf service definitions to define Set and Get RPCs, then implements a server with an in-memory dictionary backend. Python code generation from protobufs and grpcio handle the service framework, while your implementation adds validation and operation logic.

Install grpcio and grpcio-tools to generate Python code from protobuf definitions. Compile your .proto files to create service stubs and message classes, then implement the server-side servicer to handle Get and Set operations.

Implement explicit handling using a found flag in the response message or status codes returned by the Get operation. This signals to clients whether a key exists and lets you distinguish between not-found and error conditions.

Yes—write a basic client that connects to your running server and performs round-trip Set and Get operations. This functional test verifies gRPC connectivity, message serialization, and that your server handles requests correctly in a microservice environment.

gRPC uses protobuf binary serialization and HTTP/2 multiplexing for lower latency and smaller payloads compared to JSON-based REST. gRPC is better suited for microservices needing high throughput and strict schema contracts.

Yes—confirm grpcio and grpcio-tools are installed and that protobuf compilation succeeds. Dependency verification catches missing packages early and ensures your generated code matches your service interface.
