golang 手搓redis服务器

仓库地址:

仓库: https://github.com/dengjiayue/my-redis.git

实现思路:

● 协议: tcp通信
● 数据包: 长度(4byte)+方法(1byte)+数据json
● 数据处理: 单线程map读写
○ 依次处理待处理队列的请求(chan)数据,处理并返回
■ 队列大小: Max指定
■ 构建请求处理池: 不需要反复创建chan

性能压测:

package srcimport ("fmt""testing""time"
)// 压测my redis
func BenchmarkMyRedisWrite(b *testing.B) {c := NewClient("localhost:8080")go c.HandleResp()defer c.Close()//开始计时b.StartTimer()for i := 0; i < b.N; i++ {c.Set("name", "zhangsan")}// BenchmarkMyRedis-8   	   28090	     40598 ns/op	     642 B/op	      14 allocs/op
}// 压测my redis
func BenchmarkMyRedisRead(b *testing.B) {c := NewClient("localhost:8080")go c.HandleResp()defer c.Close()//开始计时b.StartTimer()for i := 0; i < b.N; i++ {c.Get("name")}// BenchmarkMyRedisRead-8             27771             44423 ns/op             588
}// 并发压测(写)
func BenchmarkMyRedisConcurrencyWrite(b *testing.B) {c := NewClient("localhost:8080")go c.HandleResp()defer c.Close()//开始计时b.StartTimer()b.RunParallel(func(pb *testing.PB) {for pb.Next() {c.Set("name", "zhangsan")}})// BenchmarkMyRedisConcurrencyWrite-8   	   90667	     12439 ns/op	     612 B/op	      14 allocs/op
}// 并发压测(读)
func BenchmarkMyRedisConcurrencyRead(b *testing.B) {c := NewClient("localhost:8080")go c.HandleResp()defer c.Close()//开始计时b.StartTimer()b.RunParallel(func(pb *testing.PB) {for pb.Next() {c.Get("name")}})// BenchmarkMyRedisConcurrencyRead-8   	   89955	     12198 ns/op	     512 B/op	      15 allocs/op
}
