Cachego - Chain driver

The chain driver deals with multiple driver at same time, it could save the key in multiple drivers and for fetching the driver will call the first one, if fails it will try the next until fail.

Usage

package main

import (
	"log"
	"time"

	bt "go.etcd.io/bbolt"

	"github.com/faabiosr/cachego/bolt"
	"github.com/faabiosr/cachego/chain"
	"github.com/faabiosr/cachego/sync"
)

func main() {
	db, err := bt.Open("cache.db", 0600, nil)
	if err != nil {
		log.Fatal(err)
	}

	cache := chain.New(
		bolt.New(db),
		sync.New(),
	)

	if err := cache.Save("user_id", "1", 10*time.Second); err != nil {
		log.Fatal(err)
	}

	id, err := cache.Fetch("user_id")
	if err != nil {
		log.Fatal(err)
	}

	log.Printf("user id: %s \n", id)
}
