**What would you like to be added**: All your requests are welcome.

update the readme

After release so many versions, maybe we need to update the readme to let users' know this lib's new features.

Improve the RTC process of Read/Write model

### Which PikiwiDB functionalities are relevant/related to the feature request? Pika 已经实现了混合存储：在内存 RedisCache 中缓存热数据，在磁盘中存储全量数据。现需要在这个基础之上，继续优化读写流程，提高吞吐，降低延时。 ### Description ![image](https://github.com/OpenAtomFoundation/pika/assets/7959374/647357dd-cb06-4bff-b297-2dcda44c1b05) from https://tech.meituan.com/2024/03/15/kv-squirrel-cellar.html ### Proposed solution process: * 1 当网络线程收到一个请求之后，会先判断是否为一个读请求，如果是，就会直接去读内存引擎 * 2 我们服务的内存引擎会缓存硬盘引擎上的热点数据，如果内存引擎命中的话，网络线程就可以直接返回结果给客户端。这样在网络线程内就实现了请求的闭环处理，相比原来的模型可以去除所有因请求流转造成的 CPU...

msec/nlb下的loadreport

最近研究nlb，nlb/src/agent/zkloadreport用于server mode下定时向zk节点/loadreport/10.0.0.1设置整个server的load信息：{timestamp: ms, cpu: cpu_percent, mem_total: mem_total, mem_free: mem_free}。我的问题是:这些上报的值在哪个模块被使用？我穷尽洪荒之力去查找也没有找到，恕我资质愚钝，请bisonliao之后的维护者出于严谨的态度指导下，这个值是怎么用的呢？

fatal bug: 除零错误

在测试nlb/src/api/nlbapi_test.c的时候发现： nlb/src/api/nlbapi.c: calc_success_ratio最后一步req_total结果为0！！！修改为： float calc_success_ratio(struct shm_servers *shm_servers, struct server_info *server) { uint32_t req_total; req_total = server->failed + server->success; if (req_total < shm_servers->shaping_request_min) { return 100.0; } return ((float)server->success) /...

nlb/src/comm/nlbfile.c:check_and_mkdir权限错误

在测试nlb/agent的时候，发现用户vag启动进程agent，agent进程创建的/var/nlb，vag用户却进不去，最后发现是nlb/src/comm/nlbfile.c:check_and_mkdir代码写的有瑕疵，现改动如下： mode_t getumask() { mode_t mask = umask(0); return mask; } /** * @brief 检查并创建目录 */ bool check_and_mkdir(const char *path) { if (!path) { return false; } if (!check_dir_exist(path)) {...
