Implement proper concurrency control mechanisms to prevent resource exhaustion and ensure thread-safe operations. Use sync.Once for thread-safe initialization to avoid memory leaks, and employ goroutine pools or semaphores to limit concurrent operations instead of spawning unlimited goroutines.
Implement proper concurrency control mechanisms to prevent resource exhaustion and ensure thread-safe operations. Use sync.Once for thread-safe initialization to avoid memory leaks, and employ goroutine pools or semaphores to limit concurrent operations instead of spawning unlimited goroutines.
For initialization that should happen only once:
var volumeBindingPlugin *vbcap.VolumeBinding
var once sync.Once
once.Do(func() {
plugin, err := vbcap.New(context.TODO(), vbArgs.VolumeBindingArgs, handle, features)
if err == nil {
volumeBindingPlugin = plugin.(*vbcap.VolumeBinding)
}
})
For controlled concurrent processing:
// Use goroutine pool instead of unlimited goroutines
semaphore := make(chan struct{}, 16)
var wg sync.WaitGroup
for _, taskInfo := range job.TaskStatusIndex[status] {
wg.Add(1)
semaphore <- struct{}{} // Acquire semaphore
go func(task *TaskInfo) {
defer func() {
<-semaphore // Release semaphore
wg.Done()
}()
// Process task
}(taskInfo)
}
wg.Wait()
This approach prevents memory leaks from repeated initialization, avoids overwhelming the system with too many concurrent operations, and ensures predictable resource usage patterns.
