Building a Worker Pool in Go

When you have a list of tasks to run concurrently, the naive approach is to spin up one goroutine per task. That works until it doesn't. A worker pool gives you bounded concurrency, backpressure, and clean shutdown without much added complexity.

The Multi-Raft Architecture

The Raft consensus protocol is widely adopted for building fault-tolerant distributed systems. It ensures that even if a node crashes or becomes unreachable, the cluster agrees on a single consistent state. However, single-group Raft does not scale well.

Runtime Choices in Distributed Systems

The Raft algorithm is language-agnostic, but the runtime underneath it is not. GC pauses, CPU scheduling, and memory models shape which implementation strategies are even possible.

When Goroutines Aren't Worth It

It's tempting to reach for goroutines whenever you see two independent operations. Two API calls? Two database queries? Spin up a goroutine, run them in parallel, cut your latency in half. Right? Sometimes. But often the added complexity buys you nothing measurable.
