大型webgame缓存研究 MemCached VB.Net C#

.Net 自带有cache 用法也不详细讲了 不要ASP.NET去操作 IIS 创建的cache 在数据量太多的情况下 即使在厉害的人物，在页面处理大数据量都不会有太好的办法

简单说，刷新所有用户的缓存 页面读数据 换 cache 效率可想而知

这里 我先贴出一个基类 VB.NET C#都有 呵呵

C#版本

 servers = { "127.0.0.1:11211", "127.0.0.1:11211" }]代码

Dim servers() As String = {"127.0.0.1:11211", "127.0.0.1:11211"}

Dim pool As SockIOPool
Dim mc As New MemcachedClient

Public Function Memcached() As Integer
'初始化池
pool = SockIOPool.GetInstance()
pool.SetServers(servers)

pool.InitConnections = 3
pool.MinConnections = 3
pool.MaxConnections = 1000

pool.SocketConnectTimeout = 1000
pool.SocketTimeout = 3000

pool.MaintenanceSleep = 30
pool.Failover = True

pool.Nagle = False
pool.Initialize()

mc = New MemcachedClient()
mc.EnableCompression = False
End Function

Public Sub RemoveMEM(ByVal key As String)
mc.Delete(key)
End Sub

Public Function SetMEM(ByVal key As String, ByVal value As Object) As Boolean
Return mc.Set(key, value)
End Function

Public Function SetMEM(ByVal key As String, ByVal value As Object, ByVal minute As Integer) As Boolean
Return mc.Set(key, value, DateTime.Now.AddMinutes(minute))
End Function

Public Function StatsMEM() As Hashtable
Return mc.Stats()
End Function

Public Function GetMEM(ByVal key As String) As Object
Return mc.Get(key)
End Function

Public Function ContainsKey(ByVal key As String) As Boolean
Return mc.KeyExists(key)
End Function

实际应用中 考虑到服务器重复使用的问题

s1_u999_dt_uMain

所有的key必须有 s1 类似开头，表明数据来自那个服务器 这样在一台服务器上多服公用就能很好的解决了

u999 就是用户编号

上例 来自 1服 编号999 用户的主表信息

s1_u999_str_bag
