teng231 / dumbcache

Simple cache list, count data using redis for microservice.

Dumbcache

Cache list, count with filter param golang, using struct, hashkey

Structure

we hash your request object to md5 hashing and add a prefix count or list. data storage to redis using get/set with expire time.(default by 2 mins)

Installing

go get github.com/teng231/dumbcache

Example

• LIST

func ListData() {
	d := &DumbCache{}
	err := d.Connect("localhost:6379", "", 0, 5*time.Second, 5*time.Minute)
	if err != nil {
		log.Print(1, err)
	}
	data := []*Partner{}
	err = d.List(&PartnerRequest{Id: 10, Limit: 2}, &data, func() (interface{}, error) {
        list, err := db.ListPartners(req)
		return list, err
	})
	if err != nil {
		log.Print(err)
	}
	log.Print(data)
}

• Count

func CountData(t *testing.T) {
	d := &DumbCache{}
	err := d.Connect("localhost:6379", "", 0, 5*time.Second, 5*time.Minute)
	if err != nil {
		log.Print(1, err)
	}
	var c int64 = 0
	err = d.Count(&PartnerRequest{Id: 10, Limit: 3}, &c, func() (int64, error) {
		count, err := db.CountPartners(req)
		return count, err
	})
	if err != nil {
		log.Print(err)
	}
	log.Print(c)
}

• CalcInt

func CalcData(t *testing.T) {
	d := &DumbCache{}
	err := d.Connect("localhost:6379", "", 0, 5*time.Second, 5*time.Minute)
	if err != nil {
		log.Print(1, err)
	}
	var c int64 = 0
	err = d.CalcInt(&PartnerRequest{Id: 10, Limit: 3}, &c, func() (int64, error) {
		count, err := db.SumPartners(req)
		return count, err
	})
	if err != nil {
		log.Print(err)
	}
	log.Print(c)
}

• Expire

func Expire() {
	d := &DumbCache{}
	err := d.Connect("localhost:6379", "", 0, 5*time.Second, 5*time.Minute)
	if err != nil {
		log.Print(1, err)
	}
	var c int64 = 0
	err = d.Expire(&PartnerRequest{Id: 10, Limit: 3})
	if err != nil {
		log.Print(err)
	}
	log.Print(c)
}
