Overview of gRPC
summary
gRPC is a high-performance RPC framework built on HTTP/2 and Protocol Buffers; a channel manages TCP connections, does pluggable name resolution, and hands off to load balancing (default pick_first, option round robin). Calls map to HTTP/2 streams and support four patterns (unary, server/client/bidirectional streaming). Features covered include interceptors, client-side deadlines with deadline propagation, cancellation propagation to downstreams, configurable retry policies (max attempts, exponential backoff), and graceful vs forceful channel shutdown.
