How Can I Efficiently Implement Global Counters in Concurrent Go Applications?

Best Practices for Implementing Global Counters in Highly Concurrent Go Applications

In developing Go applications that handle a large number of concurrent processes, it becomes crucial to implement global counters effectively. Here are the recommended approaches:

Using Sync and Atomic Packages

If the primary goal is to track a simple counter, the "sync" and "sync/atomic" packages provide efficient solutions without the overhead of channels:

import "sync/atomic"

type count32 int32

func (c *count32) inc() int32 {
    return atomic.AddInt32((*int32)(c), 1)
}

func (c *count32) get() int32 {
    return atomic.LoadInt32((*int32)(c))
}

When to Use Channels

Channels become beneficial when coordinating workers and distributing tasks. However, for simple counter operations, they may introduce unnecessary overhead:

var work_chan chan int // make() called somewhere else (buffered)

// started somewhere else
func GoCounterRoutine() {
    for {
        select {
            case c := <-work_chan:
                work_counter += c
                break
        }
    }
}

func GoWorkerRoutine() {
    for {
        // do work
        work_chan <- 1
    }    
}
