Question

最初我正在尝试将一些项目集合插入2个redis集（也许这根本不是一个好主意，但是......）。我想立即添加的条目数量： 750 +

现在我在尝试使用StackExchange.redis 客户端执行此操作时收到超时异常，有趣的是我能够使用“legacy”书架完成类似的操作< / strong>客户我以前调查过。

所以，我在某些方面肯定是错的（甚至可能在我的初始bookSleeve实现中），只是想弄清楚到底出了什么问题。以下是我与redis客户端一起使用的代码示例：的 BookSleeve：

using (var tran = connection.CreateTransaction()) { Task lastOpTask = null; tran.SuspendFlush(); try { // perform required configurations/ actions tran.Sets.Add(_redisConfiguration.DbNumber, CurrentIdsSetDbKey, stringIds); tran.Sets.Add(_redisConfiguration.DbNumber, CurrentDetailsSetDbKey, stringDetails); lastOpTask = tran.Execute(); isOperationSuccessful = true; } catch (TaskCanceledException ex) { ... } catch (TimeoutException ex1) { ... } finally { tran.ResumeFlush(); } if (lastOpTask != null) { connection.Wait(lastOpTask); ... } }

StackExchange.redis实现相同的代码：

var tran = db.CreateTransaction(); // todo: do we need to add here any condition or PipeLining? any watch/unwatch verifications? tran.SetAddAsync(CurrentIdsSetDbKey, stringIds); tran.SetAddAsync(CurrentDetailsSetDbKey, stringDetails); try { isOperationSuccessful = tran.Execute(); } catch (TaskCanceledException ex) { ... } catch (TimeoutException ex1) { ... }

开始单元测试后，我收到StackExchange客户端的下一个错误：

Message: Timeout performing EXEC, inst: 3, queue: 3, qu=0, qs=3, qc=0, wr=0/0

Source: in StackExchange.Redis.ConnectionMultiplexer.ExecuteSyncImpl[T](Message message, ResultProcessor1 processor, ServerEndPoint server) in c:\TeamCity\buildAgent\work\18a91a3757cef937\StackExchange.Redis\StackExchange\Redis\ConnectionMultiplexer.cs:line 1693 in StackExchange.Redis.RedisBase.ExecuteSync[T](Message message, ResultProcessor1 processor, ServerEndPoint server) in c:\TeamCity\buildAgent\work\18a91a3757cef937\StackExchange.Redis\StackExchange\Redis\RedisBase.cs:line 92 in StackExchange.Redis.RedisTransaction.Execute(CommandFlags flags) in c:\TeamCity\buildAgent\work\18a91a3757cef937\StackExchange.Redis\StackExchange\Redis\RedisTransaction.cs:line 51 in DFS.Cache.CacheManager.RedisStackExchange.RedisContestCacheManager.RegisterAvailableContests(IList1 contests) in d:\Projects\DFS\Code\DFS\DFS.Cache.CacheManager.RedisStackExchange\RedisContestCacheManager.cs:line 131

只是想知道，我究竟做错了什么。提前感谢您的任何建议！

P.S。对于stackEchange.redis配置，我使用Marc从github提供的配置示例（此处可用：StackExchange / StackExchange.Redis / blob / master / Docs / Configuration.md）

P.S。请参阅当前的StackExchange客户端配置文件：

var config = new ConfigurationOptions { EndPoints = { {"MasterIP", 6379}, {"SlaveIP", 6380} }, CommandMap = CommandMap.Create(new HashSet<string> { // EXCLUDE a few commands (to work with data-flow-related mode only) "INFO", "CONFIG", "CLUSTER", "PING", "ECHO", "CLIENT" }, available: false), KeepAlive = 60, // 60 sec to ensure connection is alive ConnectTimeout = 5000, // 5 sec SyncTimeout = 5000, // 5 sec ServiceName = "mymaster", // sentinel service name DefaultVersion = new Version(2, 8, 8), Password = "password" };

标准条目（在集合中使用）看起来像：

{ "Id":"08e5ffdbced046cb8f55c50e4bab822d", "Entries":0, "State":"i", "Name":"very dummy entry name value: autoGet 299", "Summary": "entry summary details, some long string 299, some common info, some data: true, 8200" "IsMultiple":true, "IsPublic":true, "MaxEntries":8200, "IsEntryVisible":true, "StartDate":"9/10/2014 12:00:00 AM" }

P.S。在Marc的回复之后，我进行了几次测试并在单元测试中遇到了一些其他错误，例如

{"Timeout performing SISMEMBER set:raw:Ids, inst: 1, queue: 6, qu=0, qs=6, qc=0, wr=0/0"} when set contains not more than 300 items.

所以我同意这是Connection问题，与当前切换到StackExchange.redis客户端无关。

以下传递正常，并在本地报告10毫秒。如果你能填补空白，我会非常感兴趣，所以我可以做一个代表性的测试来重现这个问题。请注意，qu=0, qs=3告诉我，当它超时时，我们正在等待redis服务器响应。显然，本地带宽和延迟会引起人们的兴趣，但从根本上说，它应该可以工作。我也对你的sync-timeout设置的内容感兴趣。
