memorystore-go

memorystore-go is a Go module that makes it easy to connect, read, and write to GCP's managed MemoryStore service.

Usage

Google Cloud's MemoryStore currently supports Redis and Memcache.

Unit Tests

You'll need Redis running on your local machine to run unit tests. To run them, navigate to the /tests/ directory and run

REDIS_ADDRESS=localhost REDIS_PORT=55000 REDIS_PASSWORD=put_your_password_here go test

MemoryStore

The MemoryStore interface will require Redis and Memcache implementations to look like this:

type MemoryStore interface {
	Delete(key string) error
	Get(key string) (string, error)
	Health() error
	IncrByFloat(key string, value float64) error
	Set(key string, value interface{}, expiration time.Duration) error
}

Redis

Create a new Redis Store

import memorystore_go "github.com/clearchanneloutdoor/memorystore-go"

func main() {
	config := memorystore_go.RedisConfig {
	    Address: "localhost",
		CACertFile: "file/to/cacert",
		Port: "6379",
		Password: "password",
    }

	redis, err := memorystore_go.NewRedis(config)
	if err != nil {
	    // Handle error
    }
}

Health Check

Health checks can be configured to ensure your service has a working connection to MemoryStore.

func main() {
	if err := redis.Health(); err != nil {
	    // Handle error
    }
}

Get

value, err := redis.Get("key")

IncrByFloat

if err := redis.IncrByFloat("key", 1.0); err != nil {
		// Handle error
}

Set

var value interface{}
if err := redis.Set("key", value, 0); err != nil {
    // Handle error
}

Delete

if err := redis.Delete("key"); err != nil {
    // Handle error
}

Memcache

Create a new Memcache Store
