spanner: increase sessions in batches The session pool should increase the number of sessions in the pool in batches instead of one by one when additional sessions are needed. The step size is set to 25, which means that whenever the session pool needs at least one more session, it will create a batch of 25 sessions. Go routines that request a session from the pool that cannot be served directly, initiate the asynchronous creation of a batch of sessions and are then placed in a wait. Whenever a session comes available from the BatchCreateSessions RPC or from another go routine checking a session back into the pool, it is given to one of the waiters. This means that a go routine that had to create a new batch of sessions does not have to wait until that batch is ready if a session comes available earlier. Fixes #1920.

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))
