/**
 1: 主要关注点:分布式事务一致性,高效。
 2:存储介质:redis,理由:不重要,高频数据请求,持久化过程注意点:利用redis单次操作作为原子性,利用原子性的操作结果(判断更新数量,成败)来保证整个麦位的原子性操作。
 3:分布式事务一致性(声网,服务器)。以服务端数据为准。客户端保持同声网数据一致。5分钟C端请求服务的信息,进行同步,纠正声网数据不一致问题。
 4: 存储结构:

ps: micUser持久话动作,没有归属于repo,因为需要处理并发下一致性问题。因此,在方法中,进行持久化,

* redis记录。
  micHasGroup -> set, 定于:可能麦上有人的群组(确保:麦上有人一定在该集合中), 增加时机:加入麦位之前, 减少时机:利用lua表达式控制顺序,没有人在麦上,则清理数据。(lua防止并发,麦上有人后,被移除出数据)
  micNumType -> groupUuid string, 有生命周期,缓存不存在的时候,就找数据库,更新:先删除缓存,再修改数据库。
  核心:mic -> groupUuid Map(key:i, value:Mic) 为了减少redis的数据,当mic的值为默认值时,执行的HDel
  micUser -> groupUuid Map(key:i value:MicUser)
  userInMic -> map(key:extendId, value:MicUser)  PS:userInMic同micUser 具有一致性。(原子操作)作用:用于查询某个用户在哪个麦上
