某种情况下，k-k-row 类型主从数据不同步

RouterServer::initialize中，因屏蔽setUpEtcd，导致RouterServer状态总是SLAVE，且未发现有其它地方设置为MASTER。
实际运行报错：

2020-04-28 14:44:52|140129599477504|ERROR|RouterImp.cpp:updateMasterPrx:920|master router obj not set

ConfigServer, OptServer和PropertyServer都报了这个错

但是后面上传ProxyServer等又能成功

打算手动部署opt等server，然而提示应用名非法

操作严格按照DCache和Tars的手动安装步骤来的，环境：wsl2下的ubuntu20.04

可以直接转小写吗，很麻烦。

1. 问题出现过程：
   go 程序调用 WCache_IF.go 进行写压测(通过 tars2go 工具编译 WCache.tars 获得), 未出现系统资源吃紧，在并发请求8k路总请求数10w的情况下，服务出现以下报错：
   2019-06-25 15:26:46|15803|ERROR|[TARS]ServantHandle::handle queue timeout:DCache.DCacheApp_oneKVCacheServer1-1.WCacheObj|setKV|1561015603502|600000|3000|1561015606522|10.xxx.137.193:45528

2. 一些尝试：
   1）总请求数不变，并发调整到7k时，未出现服务异常报错。
   2）调整 WCacheObj、Route、Proxy 的最大连接数、队列长度和超时时间等，没有明显改善。

3. 系统配置
   8核 32G CentOS Linux release 7.2.1511 (Core)

希望能提供些解决思路，是否由某些配置参数制约影响造成的。

Would you like to add more error handling for return values from functions like the following?

• pthread_mutex_init ⇒ TransferMutexCond::initMutexCond
• pthread_mutex_lock ⇒ RouterClientCallback::wakeUpWaitingThread

hi 我在DCache的ZSet的cache持久化到mysql时遇到两个问题。需要我手动改下数据库的表才可以。
这样正常吗？ 是不是DCache创建数据库表时就创建好呀？

1. 数据库表需要手动添加 sDCacheZSetScore 列。否则会报错。
2. 数据库表的 VALUE列需要设置为主键。否则持久化时只会有一条数据(replace into ...)。

尽管KVCacheServer支持自动淘汰数据，但写数据时（如setKV）没有去db找数据，数据一致性缺乏保证：
如setKV接口，
但是在getKV却会在没找到数据时去db查询，虽然不太熟悉源码，但感觉应该是个bug吧？

I would like to point out that identifiers like “__CONFIG_SERVER_H_” and “__DBHANDLE_H__” do not fit to the expected naming convention of the C++ language standard.
Would you like to adjust your selection for unique names?

简单看了下 程序，感觉少建了这个表。请确认。

上传发布包后，点击默认，没有任何响应

DCache作为国内十分优秀的开源项目，码云上 @zhang_donglin1 和 @D_dd 正在尝试将DCache做成RPM包集成到openEuler（国内开源操作系统）中，以更加方便更多人使用。
但是当前遇到一些问题：
由于部署阶段也需要重新编译，导致做rpm包时需要打包源码文件，但是由于rpm包一般只能包括：

0. 可执行文件
1. .so .a文件
2. service服务文件
3. 配置文件和脚本等

所以，当前这个状态下不能将DCache合入到openEuler中。

一些疑惑：
所以我们需要搞清楚为什么install.sh中会再次进行：cmake .. -DTARS_WEB_HOST=WEBHOST−DTARSTOKEN={WEB_TOKEN}
这个部署里面的编译与第一步骤中的编译：mkdir build; cd build; cmake ..; make; make release; make tar 有什么差别？
能不能在第一步编译编译后，install.sh中不再编译，是否可以通过其它配置方式来配置WEB_HOST等？

总结：当前DCache能否比较优雅地打包为一个rpm包，在部署阶段不需要重新编译，rpm包中包含所有需要编译的结果文件？

请问类似分页的limit 支持某个字段排序分页吗 看了下源码 好像 不支持某个字段排序分页
都是从hash_map中取的 存储的顺序就是按写入hash_map的顺序吗， 取也是按存储的顺序取的吗

1. Cache模块的部署目前只有主备模式吗？是否支持对主备节点进行扩容？
2. DbAccess对接后端存储有计划出操作文档吗？
3. 是否有计划组建交流讨论群？

kkv的模式下，EraseThread 在只有一个mainkey 装满内存，会死loop。 请问应该怎样处理

tc_multi_hashmap_malloc.cpp:8626
// 将脏数据移动到get链的头部，使可以继续淘汰
if (_pHead->_iGetHead == iAddr)
{
// 既是头也是尾，只有一个元素了
return RT_OK;
}

添加 使用带数据库的模块，到最后一步看不到提交按钮。可能是笔记本的显示不够高。

不能滚动，但是把页面缩小后能看到。

当有多个update请求时，由于update与writeBinLog之间未加锁,是否会引起BinLog乱序的问题，最终导致备机数据与主机不一致？

When creating Application, the IDC area cannot be empty. But I cannot find where to config the IDC area.
创建应用的时候，提示IDC地区参数不能为空，但是又找不到哪里可以配置IDC的地方。而且这个选项也没显示必填项。

文档太少了，希望能多些文档。
比如怎么后接DB，大概看了代码，还没搞清楚怎么使用

后台管理系统使用的是没有文档的内部VUE框架：let-ui ，似乎是腾讯内部的一个前端框架，找遍网络也没有看到ui文档，是否应该换为文档更丰富的开源框架以便二次开发呢？

校验值接口日志在校验出错时，不打印哪个字段报错，导致字段较多时排查较为耗时，建议可以如截图将字段名也打印出来，体验更好
