Bot框架维护用户状态 [英] Bot Framework Maintaining User State

问题描述

以前，我使用Microsoft状态服务来维护我的机器人中的用户状态.现在，Microsoft已停止支持状态服务，我已编写了一个静态对象来存储用户数据，如下所示.只想知道这是维护用户状态的正确方法，因为大约有8000个用户可能正在使用该应用程序.我只是担心它是否会引起一些并发.请提出在bot框架中是否存在更好的维护用户状态的方法

Previously i was using Microsoft state service to maintain user state in my bot. Now that Microsoft has stopped supporting state service, i have written a static object to store user data as shown below. Just wanted to know is this a right approach to maintain user state because at once around 8000 user might be using the application. I am just worried if it will cause some concurrent. Please suggest if there is a better way to maintain user state in bot framework

    private static object objectLock = new object();
    public void SetBotCache(T CaceData, string userID)
    {

  _sessionData.AddOrUpdate(userID, CaceData, (key, oldValue) => CaceData);

    }

    public T GetBotCache(string userID)
    {
        lock (objectLock)
        {
            if (_sessionData.Count > 0)
            {
                return _sessionData.First(a => a.Key == userID).Value;
            }
            else
            {
               return default(T);
            }
        }
    }

    public void RemoveCache(string userID)
    {
        lock (objectLock)
        {
            T res;
            _sessionData.TryRemove(userID, out res);
        }
    }
