orderedid

简单的序列id只用nodeid区分的唯一id. 有序. 基于数据戳.

多线程也需要提供 nodeid < 1024的id. 特点就是序列和速度.

package main

import (
	"log"

	"github.com/474420502/orderedid"
)

func main() {
	var id orderedid.OrderedID
	creator := orderedid.New(1)
	id = creator.Create()
	log.Println(id.Uint64(), id.Base58(), id.Timestamp(), id.NodeID()) // 142125288653825 27noD5f5R 1646623082475 1
}

性能测试

func BenchmarkCase(b *testing.B) {
	var id OrderedID
	creator := New(1)
	for i := 0; i < b.N; i++ {
		id = creator.Create()
	}

	b.Log(id)
}
