Talk Overview

Concurrency in Go is cheap, but goroutines are not free. In high-throughput distributed systems, unmanaged goroutine spawning leads to runaway memory usage, GC pressure, and latent goroutine leaks.

Topics Covered

1. Channel ownership patterns: who closes what and when.
2. Context propagation, cancellation deadlines, and cascading timeouts.
3. Bounded worker pools vs dynamic fan-out workers.
4. Diagnosing production leaks using net/http/pprof and goroutine stack dumps.
