package cloud

import "cloud.google.com/go"

Package cloud is the root of the packages used to access Google Cloud Services. See https://godoc.org/cloud.google.com/go for a full list of sub-packages.

Examples in this package show ways to authorize and authenticate the sub packages.

Connection Pooling

Connection pooling differs in clients based on their transport. Cloud clients either rely on HTTP or gRPC transports to communicate with Google Cloud.

Cloud clients that use HTTP rely on the underlying HTTP transport to cache connections for later re-use. These are cached to the default http.MaxIdleConns and http.MaxIdleConnsPerHost settings in http.DefaultTransport.

For gPRC clients, connection pooling is configurable to the user. Users of cloud client libraries may specify option.WithGRPCConnectionPool(n) as a client option to NewClient calls. This configures the underlying gRPC connections to be pooled and addressed in a round robin fashion. The recommended size is GOMAXPROCS.

Client Transports

The following clients use HTTP: bigquery, compute, storage, translate.

The following clients use gRPC: bigtable, container, dataproc, datastore, debugger, dlp, errorreporting, firestore, iam, language, logging, longrunning, monitoring, oslogin, profiler, pubsub, rpcreplay, spanner, speech, trace, videointelligence, vision.

Code:

// Google Application Default Credentials is the recommended way to authorize
// and authenticate clients.
//
// See the following link on how to create and obtain Application Default Credentials:
// https://developers.google.com/identity/protocols/application-default-credentials.
client, err := datastore.NewClient(context.Background(), "project-id")
if err != nil {
    // TODO: handle error.
}
_ = client // Use the client.

Code:

// Use a JSON key file associated with a Google service account to
// authenticate and authorize. Service Account keys can be created and
// downloaded from https://console.developers.google.com/permissions/serviceaccounts.
//
// Note: This example uses the datastore client, but the same steps apply to
// the other client libraries underneath this package.
client, err := datastore.NewClient(context.Background(),
    "project-id", option.WithServiceAccountFile("/path/to/service-account-key.json"))
if err != nil {
    // TODO: handle error.
}
_ = client // Use the client.
