分布式ID生成器服务
基于twitter snowflake的算法实现的ID生成器高性能的健壮的可容错的网络服务。
它提供了:
- 可配置的节点bit数和最大序列数
- 可以批量获取ID
- 基于rpcx提供网络服务，可以提供一组服务节点
- 基于rpcx,可以提供分布式的、容错的网络服务
snowflake算法的实现基于bwmarrin/snowflake, 额外提供了批量获取ID的方法。
例子
server
server 提供了一个简单的服务节点，你可以提供多个服务节点以便提供高可用性。
你还可以配置插件，使用ZooKeeper、Etcd、Consul、Nacos等作为注册中心，配置插件进行trace监控，设置黑白名单等操作，这些微服务的特性通过rpcx来实现。
client实现远程调用ID生成器的服务，这个例子采用服务地址硬编码的方式实现。如果你的服务使用了etcd、nacos等服务中心，你可以配置client使用注册中心自动获取服务节点。
客户端的例子演示了获取单个ID和获取批量ID的方法。
memcached 协议访问
除了使用 rpcx访问外，你还可以通过memcached协议获取id。
-
get id\r\n: 获取一个id -
gets 100\r\n: 一次获取100个id
性能
单个节点每秒可以产生400万左右的ID。

使用网络服务获取ID
1、256个client并发，每次只获取1个ID, ID的产生速度是 12万个ID/秒。
./bclient -addr 10.41.15.225:8972 -n 100000
total IDs: 25600000, duration: 3m31.581592489s, id/s: 120993
2、如果采用批量获取，尽量减少网络消耗，256个client并发，每次只获取100个ID, ID的产生速度是 297万个ID/秒。
./bclient -addr 10.41.15.225:8972 -n 1000000 -b 100
total IDs: 256000000, duration: 1m26.178942509s, id/s: 2970563
