README
# 简介
# [推荐使用V2版本](https://github.com/hwholiday/gid/tree/gidV2)
gid 是使用golang开发的生成分布式Id系统，基于数据库号段算法实现
###### HTTP,GRPC 对外服务
### 性能
- id 从内存生成，如果(step)步长设置的足够大,qps可达到千万+
### 可用性
- id 分配依赖mysql ,当mysql不可用的,如果内存上还有的可以继续分配
### 特性
1. 全局唯一的int64型id
2. 分配ID只访问内存
3. 可无限横向扩展
4. 依赖mysql恢复服务迅速
......
### 安装
- 初始化 mysql
```base
create database gid;
use gid;
create table segments
(
biz_tag varchar(128) not null,
max_id bigint null,
step int null,
remark varchar(200) null,
create_time bigint null,
update_time bigint null,
constraint segments_pk
primary key (biz_tag)
) ENGINE = InnoDB
DEFAULT CHARSET = utf8mb4
COLLATE = utf8mb4_bin;
INSERT INTO segments(`biz_tag`, `max_id`, `step`, `remark`, `create_time`, `update_time`)
VALUES ('test', 0, 100000, 'test', 1591706686, 1591706686);
```
- 编译运行项目
```base
git clone https://github.com/hwholiday/gid.git
cd gid/cmd
go build -o gidsrv
./gidsrv -conf ./gid.toml
```
#### 压测
```base
BenchmarkService_GetId-4 2046296 583 ns/op
```
#### 健康检查
- curl http://127.0.0.1:8080/ping
#### 获取ID
- test6 获取该 tag 类型的 id
- curl http://127.0.0.1:8080/id/test6
#### 获取雪花算法生成的ID
- curl http://127.0.0.1:8080/rand/id
#### 创建 tag
- biz_tag tag 名称
- max_id 从这里开始派发ID
- step 步长
- remark 备注
- {"biz_tag":"test6","max_id":0,"step":10,"remark":"test6 tag"}
- curl -H "Content-Type:application/json" -X POST --data '{"biz_tag":"test6","max_id":0,"step":10,"remark":"test6 tag"}' http://127.0.0.1:8080/tag
#### 重点SQL
```base
Begin
UPDATE table SET max_id=max_id+step WHERE biz_tag=xxx
SELECT tag, max_id, step FROM table WHERE biz_tag=xxx
Commit
```
