🐉 Dragonfly

Domesticate dragonfly for Snapp ODE. Setting up dragonfly with Docker, deploy on Kubernetes with a single Pod, deploy using Charts. Testing dragonfly with a simple load testing application.

What is Dragonfly?

Dragonfly is a drop-in Redis replacement that scales vertically to support millions of operations per second and terabyte sized workloads, all on a single instance. Dragonfly gives you so much more with a complete, modern engine architecture that’s fully compatible with the Redis and Memcached APIs.

docker pull docker.dragonflydb.io/dragonflydb/dragonfly

start

docker run --ulimit memlock=-1 -p 6379:6379 docker.dragonflydb.io/dragonflydb/dragonfly

Now you can use redis sdk to connect to dragonfly cluster.

rdb := redis.NewClient(&redis.Options{
		Addr:     "localhost:6379",
		Password: "", // no password set
		DB:       0,  // use default DB
	})

err := rdb.Set(ctx, "key", "value", 0).Err()
if err != nil {
  panic(err)
}

val, err := rdb.Get(ctx, "key").Result()
if err != nil {
  panic(err)
}
fmt.Println("key", val)

Charts

Dragonfly also provides helm charts in order to deploy an instance on kubernetes.

helm install dragonfly charts
