如何在Go语言中处理分布式大数据任务

type Task struct {
    ID   int
    Data []byte
}

func main() {
    tasks := []Task{
        {ID: 1, Data: []byte("data1")},
        {ID: 2, Data: []byte("data2")},
        {ID: 3, Data: []byte("data3")},
        // more tasks...
    }

    results := make(chan Task, len(tasks))
    done := make(chan struct{})

    // Create worker goroutines and start processing tasks
    for i := 0; i < runtime.NumCPU(); i++ {
        go func() {
            for task := range tasks {
                result := processTask(task)
                results <- result
            }
        }()
    }

    // Wait for all tasks to be processed
    go func() {
        for i := 0; i < len(tasks); i++ {
            <-results
        }
        close(done)
    }()

    <-done
    close(results)
}

func processTask(task Task) Task {
    // Process the task here...
    // Return the result
    return task
}

type DataShard struct {
    ShardID int
    Data    []byte
}

func main() {
    data := []DataShard{
        {ShardID: 1, Data: []byte("data1")},
        {ShardID: 2, Data: []byte("data2")},
        {ShardID: 3, Data: []byte("data3")},
        // more data shards...
    }

    results := make(chan DataShard, len(data))
    done := make(chan struct{})

    // Create worker goroutines and start processing data shards
    for i := 0; i < runtime.NumCPU(); i++ {
        go func() {
            for shard := range data {
                result := processDataShard(shard)
                results <- result
            }
        }()
    }

    // Wait for all data shards to be processed
    go func() {
        for i := 0; i < len(data); i++ {
            <-results
        }
        close(done)
    }()

    <-done
    close(results)
}

func processDataShard(shard DataShard) DataShard {
    // Process the data shard here...
    // Return the processed data shard
    return shard
}
