spanner: Use a connection pool The Spanner client library did round-robin connection pooling manually. This changes it to use the new connection pooling in gRPC. This can BREAK user code in the following specific case: * The user specified a value for NumChannels in ClientConfig * The user specified a different value for WithGRPCConnectionPool Example: The following code would work prior to this change, while it will return an error after this change. client, err := NewClientWithConfig( context.Background(), "projects/p/instances/i/databases/d", ClientConfig{NumChannels: 8}, option.WithGRPCConnectionPool(16), ) The example code does however represent a mis-configuration that would break session-channel affiliation, and also would not make any sense. Instead of silently ignoring the mis-configuration and use one of the configured values, the client library now returns an error. This change DEPRECATES ClientConfig.NumChannels. Updates #1777.

Go packages for Google Cloud Platform services.
import "cloud.google.com/go"
To install the packages on your system, do not clone the repo. Instead:
Change to your project directory:
cd /my/cloud/project
Get the package you want to use. Some products have their own module, so it's best to go get
the package(s) you want to use:
$ go get cloud.google.com/go/firestore # Replace with the package you want to use.
NOTE: Some of these packages are under development, and may occasionally make backwards-incompatible changes.
NOTE: Github repo is a mirror of https://code.googlesource.com/gocloud.
Alpha status: the API is still being actively developed. As a result, it might change in backward-incompatible ways and is not recommended for production use.
Beta status: the API is largely complete, but still has outstanding features and bugs to be addressed. There may be minor backwards-incompatible changes where necessary.
Stable status: the API is mature and ready for production use. We will continue addressing bugs and feature requests.
Documentation and examples are available at pkg.go.dev/cloud.google.com/go
We support the two most recent major versions of Go. If Google App Engine uses an older version, we support that as well.
By default, each API will use Google Application Default Credentials for authorization credentials used in calling the API endpoints. This will allow your application to run in many environments without requiring explicit configuration.
client, err := storage.NewClient(ctx)
To authorize using a JSON key file, pass option.WithCredentialsFile
to the NewClient
function of the desired package. For example:
client, err := storage.NewClient(ctx, option.WithCredentialsFile("path/to/keyfile.json"))
You can exert more control over authorization by using the golang.org/x/oauth2
package to create an oauth2.TokenSource
. Then pass option.WithTokenSource
to the NewClient
function: snip:# (auth-ts)
tokenSource := ...
client, err := storage.NewClient(ctx, option.WithTokenSource(tokenSource))
