/**
* Represents an implementation of {@link IDGenerator}
* 基于百度开源项目 uid-generator 的增强版，Snowflake Java 实现版本。项目 Github：https://github.com/baidu/uid-generator
* <p>
* uid-generator 通过对 64 位数字分区来生成唯一 ID，由以下组成：
* <p>
* -----------------------------------------------------------------------------------
* | sign | delta seconds | worker id | SEQUENCE
* -----------------------------------------------------------------------------------
* 1bits 28bits 22bits 13bits
* -----------------------------------------------------------------------------------
* 其中 delta seconds 为 当前时间 - 指定起始时间。
* 该版本有三个问题
* 1. delta seconds 位数有限，28bits 也只能允许运行 8.7 年左右。
* 2. worker id 生成号码为用后即弃，可容纳重启次数有限。
* 3. 微服务分布式的情况下，无法使用统一数据源，则不同服务生成 worker id 时会重复
* <p>
* 于是做出以下改进
* 1. worker id 拆分成 data center id，每个服务通过约定指定自己的 data center id 。
* 2. worker id 通过 redis 自增指定，设计为首尾相连的环形，自增数字达到设定的最大值时，会从0开始。
* 2. 不限制使用 delta seconds 的位数，则实现了无限时间的使用。当位数增长到 64 为后，改用 BigInteger 的位运算实现。
* <p>
* 经测试，BigInteger 实现时，性能降低 60% 左右，每秒发号约为 100w~150w。
* 现在 uid 由以下组成
* ---------------------------------------------------------------------------------------------------------
* | sign(length < 64) | delta seconds (unlimited) | data center id | worker id | SEQUENCE
* ---------------------------------------------------------------------------------------------------------
* 1bits 28bits 22bits 22bits 13bits
* ---------------------------------------------------------------------------------------------------------
* 其中 data center id + worker id + SEQUENCE 设定的位数不大于 63。
* <p>
* 使用注意：
* 1. 号码的位数不固定，会随着时间增长。data center id + worker id + SEQUENCE 总数设定越大，号码位数越长
* 2. 各个分区的位数、起始时间一旦设定完成投入使用，则后续不能更改。否则会导致发号重复。
