当KVCacheServer或者MKVCacheServer有更新时，已发布的module如何更新？
Would you like to add more error handling for return values from functions like the following?
是否有性能数据的介绍？
如，跟redis或其他缓存的对比？

Router/Transfer.cpp 中，第63行：
int rc = _dbHandle->updateTransferingRecord(transInfoNew,
transInfoComplete,
cleanSrc,
cleanDest,
cleanSrcHasInc,
cleanDestHasInc,
0);在调用 DbHandle::updateTransferingRecord 函数时，iReturn 参数硬编码为0，且我未能找到其他地方有调用 DbHandle::updateTransferingRecord 这个重载函数，那么 DbHandle.cpp 中，在多次执行后，必然会进入到第1855行的分支，而第1871行到1955行的分支没有路径进入，那么其存在有什么特殊的意义吗？
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?

上传发布包后，点击默认，没有任何响应
在64G内存的主机上交叉部署7组MKVCacheServer后，每个server分配1G内存，由于没有数据，实际占用内存并不多。2周后发现buffer/cache竟然占用了61G。经过清理，发现pagecache占用了绝大部分内存。
想知道这种情况是否是程序bug？还是可以忽略？

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
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。
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。

推测可能是从节点的binlog比主节点的慢了超过300秒，导致切换失败。
分析了下原因，发现两台主机的时钟不同步。（注意：此问题并不能确认是时钟不同步导致，只是排除不合理因素）
问题1：这个错误的具体原因是什么？如果想屏蔽这个错误、保证正常的主备切换，应该修改哪个文件的时间？或者有其他什么方法？
同步了下时钟，待binlog更新后，出现新问题：

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？
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
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：
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？
某种情况下，k-k-row 类型主从数据不同步

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;
}
简单看了下 程序，感觉少建了这个表。请确认。

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。

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。
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
DbAcess的配置没放出来呀
