智能工业管理系统高负载场景优化：工厂旺季 / 批量生产如何保障稳定运行？技术方案解析

// 订单服务接口示例
public interface IOrderService
{
    // 异步处理批量订单
    Task<ProcessResult> ProcessBatchOrdersAsync(IEnumerable<ProductionOrder> orders);
    
    // 获取订单状态
    Task<OrderStatus> GetOrderStatusAsync(string orderId);
}

// 实现高并发订单处理
public class OrderService : IOrderService
{
    private readonly IOrderRepository _orderRepository;
    
    public async Task<ProcessResult> ProcessBatchOrdersAsync(IEnumerable<ProductionOrder> orders)
    {
        // 使用并行处理提高吞吐量
        var results = await Task.WhenAll(orders.Select(ProcessSingleOrderAsync));
        return new ProcessResult { SuccessCount = results.Count(r => r.IsSuccess) };
    }
    
    private async Task<ProcessResult> ProcessSingleOrderAsync(ProductionOrder order)
    {
        // 异步处理单个订单
        try
        {
            await _orderRepository.AddAsync(order);
            return ProcessResult.Success();
        }
        catch (Exception ex)
        {
            return ProcessResult.Failure(ex.Message);
        }
    }
}

// 使用Entity Framework Core实现数据访问优化
public class ProductionDataService
{
    private readonly ProductionDbContext _context;
    private readonly IDistributedCache _cache;
    
    public ProductionDataService(ProductionDbContext context, IDistributedCache cache)
    {
        _context = context;
        _cache = cache;
    }
    
    // 带缓存的生产数据查询
    public async Task<ProductionData> GetProductionDataAsync(string deviceId)
    {
        var cacheKey = $"production_data_{deviceId}";
        var cachedData = await _cache.GetStringAsync(cacheKey);
        
        if (!string.IsNullOrEmpty(cachedData))
        {
            return JsonSerializer.Deserialize<ProductionData>(cachedData);
        }
        
        // 数据库查询
        var data = await _context.ProductionData
            .AsNoTracking()
            .FirstOrDefaultAsync(p => p.DeviceId == deviceId);
        
        if (data != null)
        {
            // 缓存数据，设置5分钟过期时间
            await _cache.SetStringAsync(cacheKey, 
                JsonSerializer.Serialize(data), 
                new DistributedCacheEntryOptions { AbsoluteExpirationRelativeToNow = TimeSpan.FromMinutes(5) });
        }
        
        return data;
    }
}
