notify-keyspace-events "Ex"

# K    键空间通知，以__keyspace@<db>__为前缀
# E    键事件通知，以__keysevent@<db>__为前缀
# g    del , expipre , rename 等类型无关的通用命令的通知, ...
# $    String命令
# l    List命令
# s    Set命令
# h    Hash命令
# z    有序集合命令
# x    过期事件（每次key过期时生成）
# e    驱逐事件（当key在内存满了被清除时生成）
# A    g$lshzxe的别名，因此”AKE”意味着所有的事件
