StackExchange.Redis 将线程集中的所有命令组合在一起
示例
class ToyProfiler : IProfiler
{
public ConcurrentDictionary<Thread, object> Contexts = new ConcurrentDictionary<Thread, object>();
public object GetContext()
{
object ctx;
if(!Contexts.TryGetValue(Thread.CurrentThread, out ctx)) ctx = null;
return ctx;
}
}
//...
ConnectionMultiplexer conn = /* initialization */;
var profiler = new ToyProfiler();
var thisGroupContext = new object();conn.RegisterProfiler(profiler);
var threads = new List<Thread>();
for (var i = 0; i < 16; i++)
{
var db = conn.GetDatabase(i);
var thread =
new Thread( delegate()
{
var threadTasks = new List<Task>();
for (var j = 0; j < 1000; j++)
{
var task = db.StringSetAsync("" + j, "" + j); threadTasks.Add(task);
}
Task.WaitAll(threadTasks.ToArray());
}
);
profiler.Contexts[thread] = thisGroupContext; threads.Add(thread);
}conn.BeginProfiling(thisGroupContext);
threads.ForEach(thread => thread.Start());
threads.ForEach(thread => thread.Join());
IEnumerable<IProfiledCommand> timings = conn.FinishProfiling(thisGroupContext);最后，计时将包含16,000个IProfiledCommand对象-每个发布给redis的命令一个。
