gorm-cache

gorm-cache aims to provide a look-aside, almost-no-code-modification cache solution for gorm v2 users.

Redis, where cached data stores in Redis (if you have multiple servers running the same procedure, they don't share the same space in Redis)

Overview

即插即用

旁路缓存

数据源使用 Redis

会话级缓存

基于 Pacific73/gorm-cache 修改

Install

go get github.com/ccever1/gorm-cache

Usage

package main

import (
	"github.com/ccever1/gorm-cache/cache"
	"github.com/ccever1/gorm-cache/config"
	"github.com/ccever1/gorm-cache/util"
	"github.com/go-redis/redis/v8"
	"gorm.io/driver/mysql"
	"gorm.io/gorm"
	"gorm.io/gorm/logger"
)

func main() {
	dsn := "user:pass@tcp(127.0.0.1:3306)/database_name?charset=utf8mb4"
	lg := logger.Default.LogMode(logger.Info)
	db, _ := gorm.Open(mysql.Open(dsn), &gorm.Config{Logger: lg})

	redisClient := redis.NewClient(&redis.Options{
		DB:   2,
		Addr: "localhost:6379",
	})

	cache, _ := cache.NewGormCache(&config.CacheConfig{
		RedisConfig: cache.NewRedisConfigWithClient(redisClient),
		DebugMode:   true,
	})
	//More options in `config.config.go`
	db.Use(cache) // use gorm plugin

	var users []User

	dbx := db.Where("maxsuccessions > ?", 16).Session(&gorm.Session{})

	dbx.InstanceSet(util.GormCacheTTL, 5000).Find(&users) // search cache not hit, objects cached, 5000ms

	dbx.InstanceSet(util.GormCacheTTL, 5000).Find(&users) // search cache hit

	dbx.Find(&users) // do not use cache

}
