NOTE: These packages are experimental, and may occasionally make backwards-incompatible changes.

Go packages for Google Cloud Platform services. Supported APIs include:

• Google Cloud Datastore
• Google Cloud Storage
• Google Cloud Pub/Sub
• Google Cloud Container Engine

import "google.golang.org/cloud"

Documentation and examples are available at https://godoc.org/google.golang.org/cloud.

Authorization, throughout the package, is delegated to the godoc.org/golang.org/x/oauth2. Refer to the godoc documentation for examples on using oauth2 with the Cloud package.

Google Cloud Datastore (docs) is a fully managed, schemaless database for storing non-relational data. Cloud Datastore automatically scales with your users and supports ACID transactions, high availability of reads and writes, strong consistency for reads and ancestor queries, and eventual consistency for all other queries.

Follow the activation instructions to use the Google Cloud Datastore API with your project.

https://godoc.org/google.golang.org/cloud/datastore

type Post struct {
	Title       string
	Body        string `datastore:",noindex"`
	PublishedAt time.Time
}
keys := []*datastore.Key{
	datastore.NewKey(ctx, "Post", "post1", 0, nil),
	datastore.NewKey(ctx, "Post", "post2", 0, nil),
}
posts := []*Post{
	{Title: "Post 1", Body: "...", PublishedAt: time.Now()},
	{Title: "Post 2", Body: "...", PublishedAt: time.Now()},
}
if _, err := datastore.PutMulti(ctx, keys, posts); err != nil {
	log.Println(err)
}

Google Cloud Storage (docs) allows you to store data on Google infrastructure with very high reliability, performance and availability, and can be used to distribute large data objects to users via direct download.

https://godoc.org/google.golang.org/cloud/storage

// Read the object1 from bucket.
rc, err := storage.NewReader(ctx, "bucket", "object1")
if err != nil {
	log.Fatal(err)
}
slurp, err := ioutil.ReadAll(rc)
rc.Close()
if err != nil {
	log.Fatal(err)
}

Google Cloud Pub/Sub is in Alpha status. As a result, it might change in backward-incompatible ways and is not recommended for production use. It is not subject to any SLA or deprecation policy.

Google Cloud Pub/Sub (docs) allows you to connect your services with reliable, many-to-many, asynchronous messaging hosted on Google's infrastructure. Cloud Pub/Sub automatically scales as you need it and provides a foundation for building your own robust, global services.

https://godoc.org/google.golang.org/cloud/pubsub

// Publish "hello world" on topic1.
msgIDs, err := pubsub.Publish(ctx, "topic1", &pubsub.Message{
	Data: []byte("hello world"),
})
if err != nil {
	log.Println(err)
}
// Pull messages via subscription1.
msgs, err := pubsub.Pull(ctx, "subscription1", 1)
if err != nil {
	log.Println(err)
}
