gRPC Python Patterns

High-performance RPC framework for microservice communication.

Overview

• Internal microservice communication (lower latency than REST)
• Streaming data (real-time updates, file transfers)
• Polyglot environments (shared proto definitions)
• Strong typing between services (compile-time validation)
• Bidirectional streaming (chat, gaming, real-time sync)

When NOT to Use

• Public APIs (prefer REST/GraphQL for browser compatibility)
• Simple CRUD with few services (REST is simpler)
• When HTTP/2 is not available
