dcache's Introduction

背景

DCache是一个基于TARS框架开发的分布式NoSQL存储系统,数据采用内存存储,支持连接后端DB实现数据持久化。DCache采用集群模式,具有高扩展、高可用的特点。

DCache在腾讯内部有大量业务使用,日访问总量超万亿次。

DCache具有以下特点

  • 高性能存储引擎,支持key-value,k-k-row,list,set,zset多种数据结构,支持数据持久化落地后端DB。
  • 集群模式,高扩展,高可用,支持异地镜像,就近接入。
  • 通过名字访问,支持同步、异步、单向RPC调用。
  • 高效运维平台,在线完成服务部署、扩缩容、迁移,以及服务配置,服务调用质量监控。
  • 业务无须和直接和mysql交互, DCache会自动缓写DB

支持平台

  • Linux

开发语言

  • C++

快速上手

DCache的安装建议通过TarsWeb的服务市场安装.

文档

DCache接口使用方法请参考文档Proxy接口指南,更多文档请查看docs目录

数据库说明

DCache框架依赖mysql数据库, 当DCache安装以后, 它自动会创建以下数据库

  • db_cache_web: DCache的web依赖
  • db_dcache_relation: DCacheOptServer/ConfigServer/PropertyServer/DCacheWebServer依赖, 注意DCacheWebServer只是会创建它, 并不是直接使用它
  • db_dcache_property: DCache统计数据库, PropertyServer依赖

需要在安装过程中正确设置配置文件中的数据库的地址.

实际每套创建的每套Cache, 如果设置了数据落地, 那么也依赖mysql, 这个在DCache管理平台上可以设置, 安装时正确配置即可.

dcache's Issues

DbAcess

DbAcess的配置没放出来呀

主备切换不好使

场景:手动停止CacheServer的主节点。

控制台上Router服务显示错误信息:
2019-10-09 14:05:32|SwitchThread:: slaveBinlogdif diffBinlogTime(1570590077) > 300 DCache.myAppMKVtest2MKVCacheServer1-2

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:

2019-10-09 14:08:26|removeSwitchModule moduleName : myAppMKVtest2| switch tasks : 0
日志中上述内容循环打印,看上去没什么异常,但控制台上Router服务显示错误信息:
DoSwitchThread::doSwitchMaterSlave switch times over the SwitchMaxTimes: 3, so not do switch groupName:myAppMKVtest2MKVGroup1, masterServer:DCache.myAppMKVtest2MKVCacheServer1-1, slaveServer:DCache.myAppMKVtest2MKVCacheServer1-2

切换超过3次没有成功。客户端进行访问时,也是报错超时,实际上没有发生切换。
具体原因不清楚。

从节点CacheServer的日志不断的循环输出如下内容:
2019-10-09 14:18:26|24350|ERROR|[MKBinLogThread::syncCompress] getLogCompress exception:server unknown exception: ret:-10 msg:[ServantProxy::invoke errno:-10,info:,servant:DCache.myAppMKVtest2MKVCacheServer1-1.BinLogObj,func:getLogCompressWithPart,reqid:0]

其中,10.4.120.136 这个ip是主节点。

问题2:这个错误的具体原因是什么?如何解决?

性能问题

是否有性能数据的介绍?
如,跟redis或其他缓存的对比?

RouterServer主备状态错误

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:

CMake报错

cmake version 3.10.2
执行cmake时报错:
-- The C compiler identification is GNU 7.5.0
-- The CXX compiler identification is unknown
-- Check for working C compiler: /usr/bin/cc
-- Check for working C compiler: /usr/bin/cc -- works

CMake Error at CMakeLists.txt:3 (project):
No CMAKE_CXX_COMPILER could be found.

Tell CMake where to find the compiler by setting either the environment
variable "CXX" or the CMake cache entry CMAKE_CXX_COMPILER to the full path
to the compiler, or to the compiler name if it is in the PATH.

迁移过程中的执行路径问题

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?

insertKV代理服务存在bug

Proxy服务中的ProxyImp::insertKV函数中,如下行:
prxWCache->async_setKV(cb, req);
修改为:
prxWCache->async_insertKV(cb, req);

在DCache的ZSet持久化时,遇到的两个问题

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?

  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 ...)。

压测 KVCacheServer 报错

  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。

校验值接口日志有待改进

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

DCache部署过程的一些疑问

  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?

版本升级

Tars-framwork已经升级到v2.1.0。
DCache是否有相应的升级计划?

limit排序分页

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

DCache make 失败

pagecache 被大量占用

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?

【openEuler】如何更加优雅地将DCache做成RPM包以集成到openEuler操作系统中

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:

  1. 可执行文件
  2. .so .a文件
  3. service服务文件
  4. 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?
