Deep Dive: gRPC
summary
gRPC-Go is a native implementation in Go that exposes channel and subchannel abstractions mapping logical RPCs to physical connections; the code path shows resolver → balancer → subchannel → transport → stream, with round‑robin and pick‑first balancers implemented and pick‑first connecting to only one backend. Features demonstrated include native bi‑directional streaming, service config driven load‑balancing and RPC retries, and binary logging and channelz for per‑transport runtime metrics used to debug connections and flow control.
