Sample pipelining

func ExamplePipeline() {
	c, err := NewClusterClient([]string{"127.0.0.1:3320"})
	if err != nil {
		// Handle this error
	}
	dm, err := c.NewDMap("mydmap")
	if err != nil {
		// Handle this error
	}

	ctx := context.Background()

	pipe, err := dm.Pipeline()
	if err != nil {
		// Handle this error
	}

	futurePut, err := pipe.Put(ctx, "key-1", "value-1")
	if err != nil {
		// Handle this error
	}

	futureGet := pipe.Get(ctx, "key-1")

	err = pipe.Exec(context.Background())
	if err != nil {
		// Handle this error
	}

	err = futurePut.Result()
	if err != nil {
		// Handle this error
	}

	gr, err := futureGet.Result()
	if err != nil {
		// Handle this error
	}
	value, err := gr.String()
	if err != nil {
		// Handle this error
	}
	fmt.Println(value)
}
