项目repo地址 https://github.com/yongman/tidis
Tidis是分布式数据库，支持redis协议，多种数据结构支持，编写语言为golang。
Tidis工作角色类似于TIDB，提供协议转换和数据结构计算，底层使用TiKV分布式kv存储引擎，采用raft数据复制的数据高可用和两阶段提交实现的分布式事务。
特点：
- redis协议兼容
- 集群规模线性扩展
- 计算与存储分离
- 分布式事务支持
- 数据安全，raft复制，数据保证不丢失
编译：
git clone https://github.com/yongman/tidis.git
make
运行tikv集群：
参考pingcap官方教程https://github.com/pingcap/docs/blob/master/op-guide/docker-deployment.md
运行tidis：
bin/bin/tidis-server -backend <pd address, ip:port>
redis-cli -p 5379
