SnowflakeIdHelper

分布式雪花 ID 生成器（Twitter Snowflake 算法的 C# 实现）。

文件说明

文件 内容
SnowflakeIdHelper.cs ID 生成器、建造者、ID 反解、单例管理

核心特点

  • 杜绝时钟回拨：使用 Stopwatch 硬件单调计数器代替系统时钟
  • 线程安全：lock + Interlocked 保证并发正确
  • 全局单例：SnowflakeIdHelper.Next() 开箱即用
  • 集群支持：WorkerId + DataCenterId 共 10bit，最多 1024 节点

ID 结构

[1bit保留] [41bit时间戳] [5bit DataCenter] [5bit Worker] [12bit 序列号]
  • 每毫秒 4096 个 ID
  • 每节点每天可生成约 3500 亿个

快速开始

// 开箱即用
long id = SnowflakeIdHelper.Next();

// 自定义机器码
SnowflakeIdHelper.SetDefault(b => b.SetWorkerId(5).SetDataCenterId(2));
long id = SnowflakeIdHelper.Next();

// 创建独立实例
var gen = SnowflakeIdHelper.Build()
    .SetWorkerId(10)
    .SetDataCenterId(1)
    .SetEpoch(new DateTime(2024, 1, 1, 0, 0, 0, DateTimeKind.Utc))
    .Create();
long id = gen.NextId();

ID 反解

var info = SnowflakeIdHelper.Parse(id);
Console.WriteLine($"时间: {info.Timestamp}");
Console.WriteLine($"DC: {info.DataCenterId}, Worker: {info.WorkerId}");
Console.WriteLine($"序号: {info.Sequence}");

集群 WorkerId 分配方案

方案 适用规模 实现
配置文件 5-10 台 手动配置唯一的 WorkerId+DataCenterId
数据库自增 50 台内 INSERT + LAST_INSERT_ID() % 1024
Redis INCR 100+ 台 redis.Incr("snowflake:counter") % 1024
ZooKeeper 弹性扩缩 临时顺序节点序号 % 1024

特殊情况

// 指定时间生成（使用系统时钟，受回拨影响）
long id = SnowflakeIdHelper.Next(DateTime.UtcNow);
