 Godis 是一个用 Go 语言实现的 Redis 服务器。本项目旨在为尝试使用 Go 语言开发高并发中间件的朋友提供一些参考。
 
 关键功能:
-- 支持 string, list, hash, set, sorted set 数据结构
+- 支持 string, list, hash, set, sorted set, bitmap 数据结构
 - 自动过期功能(TTL)
 - 发布订阅
 - 地理位置
 - AOF 持久化及 AOF 重写
+- 加载和导出 RDB 文件
 - Multi 命令开启的事务具有`原子性`和`隔离性`. 若在执行过程中遇到错误, godis 会回滚已执行的命令
 - 内置集群模式. 集群对客户端是透明的, 您可以像使用单机版 redis 一样使用 godis 集群
   - `MSET`, `MSETNX`, `DEL`, `Rename`, `RenameNX`  命令在集群模式下原子性执行, 允许 key 在集群的不同节点上
