Module 1: Deep Dive into Internal Mechanics

• Memory Architecture: Stack vs. Heap allocation, escape analysis, and reducing GC pressure.
• The Scheduler: Understanding the M:N scheduler model, GOMAXPROCS, and Goroutine throttling.
• Data Structures Internals: In-depth analysis of Maps, Slices, and Interfaces (itab tables) for performance-critical code.

4. Networking, RPC, and services

• gRPC (v1 & v2): use protobuf v3, context propagation, interceptors for auth/metrics, enable reflection in dev.
• HTTP servers: use http.Server with Read/Write/Idle timeouts; graceful shutdown using context and Server.Shutdown.
• REST & JSON: use encoding/json or jsoniter for speed; prefer strict decoding with Decoder.DisallowUnknownFields where needed.
• Connection management: reuse http.Client with proper Transport settings; configure MaxIdleConns, IdleConnTimeout.
• TLS & security: prefer TLS 1.3, use system cert pools, validate hostnames, enable HSTS on APIs.
