Go 分布式令牌桶限流 + 兜底策略
上篇文章提到固定时间窗口限流无法处理突然请求洪峰情况，本文讲述的令牌桶线路算法则可以比较好的处理此场景。

1. 单位时间按照一定速率匀速的生产 token 放入桶内，直到达到桶容量上限。
   
2. 处理请求，每次尝试获取一个或多个令牌，如果拿到则处理请求，失败则拒绝请求。

优点

可以有效处理瞬间的突发流量，桶内存量 token 即可作为流量缓冲区平滑处理突发流量。

缺点

实现较为复杂。

core/limit/tokenlimit.go

分布式环境下考虑使用 redis 作为桶和令牌的存储容器，采用 lua 脚本实现整个算法流程。

Ignite Realtime Blog: Openfire 4.6.7 released (Log4j 2.17.1 only change)
Openfire 4.6.7 has been released with only a single change to bump the bundled log4j library to version 2.17.1. Whilst we do not believe Openfire to be vulnerable to the CVEs associated with the log4j 2.17.0 and 2.17.1 releases, we realize that many folks are running naive security scanners that are simply checking for bundled jar versions.

go 语言位操作库 bitset
bitset库 实现了 bitsets 数据结构，这是一种正整数和布尔值映射关系的结构，它比 map[uint]bool 更高效

bitsets 基本思想是用一个 bit 位来标记某个元素对应的 Value，每一位表示一个数，1 表示存在，0 表示不存在
比如我要表示 1, 3, 7 这 3 个数

1. 构造一个空白 bitsets：00000000
   
2. 每位代表的值如下：76543210
