    "fmt"

    cache "github.com/morkid/gocache-elasticsearch/v7"

    "github.com/elastic/go-elasticsearch/v7"

)

func latency() {

    // network latency simulation

    // just for testing

    time.Sleep(1 * time.Second)

}

func main() {

    config := elasticsearch.Config{

        Addresses: []string{

            "http://localhost:9200",

        },

    }

    es, err := elasticsearch.NewClient(config)

    if nil != err {

        panic(err)

    }

    adapterConfig := cache.ElasticCacheConfig{

        Client:    es,

        Index:     "example",

        ExpiresIn: 10 * time.Second,

    }

    adapter := *cache.NewElasticCache(config)

    adapter.Set("foo", "bar")

    if adapter.IsValid("foo") {

        value, err := adapter.Get("foo")

        if nil != err {

            fmt.Println(err)

        } else if value != "bar" {

            fmt.Println("value not equals to bar")

        } else {

            fmt.Println(value)

        }

        adapter.Clear("foo")

        latency()

        if adapter.IsValid("foo") {

            fmt.Println("Failed to remove key foo")

        }

    }
