# Contributing
1. Sign one of the contributor license agreements below.
1. `go get golang.org/x/review/git-codereview` to install the code reviewing tool.
1. You will need to ensure that your `GOBIN` directory (by default
`$GOPATH/bin`) is in your `PATH` so that git can find the command.
1. If you would like, you may want to set up aliases for git-codereview,
such that `git codereview change` becomes `git change`. See the
[godoc](https://godoc.org/golang.org/x/review/git-codereview) for details.
1. Should you run into issues with the git-codereview tool, please note
that all error messages will assume that you have set up these
aliases.
1. Get the cloud package by running `go get -d cloud.google.com/go`.
1. If you have already checked out the source, make sure that the remote git
origin is https://code.googlesource.com/gocloud:
git remote set-url origin https://code.googlesource.com/gocloud
1. Make sure your auth is configured correctly by visiting
https://code.googlesource.com, clicking "Generate Password", and following
the directions.
1. Make changes and create a change by running `git codereview change <name>`,
provide a commit message, and use `git codereview mail` to create a Gerrit CL.
1. Keep amending to the change with `git codereview change` and mail as your receive
feedback. Each new mailed amendment will create a new patch set for your change in Gerrit.
## Integration Tests
In addition to the unit tests, you may run the integration test suite.
To run the integrations tests, creating and configuration of a project in the
Google Developers Console is required.
After creating a project, you must [create a service account](https://developers.google.com/identity/protocols/OAuth2ServiceAccount#creatinganaccount).
Ensure the project-level **Owner**
[IAM role](console.cloud.google.com/iam-admin/iam/project) role is added to the
service account. Alternatively, the account can be granted all of the following roles:
- **Editor**
- **Logs Configuration Writer**
- **PubSub Admin**
Once you create a project, set the following environment variables to be able to
run the against the actual APIs.
- **GCLOUD_TESTS_GOLANG_PROJECT_ID**: Developers Console project's ID (e.g. bamboo-shift-455)
- **GCLOUD_TESTS_GOLANG_KEY**: The path to the JSON key file.
- **GCLOUD_TESTS_API_KEY**: Your API key.
Firestore requires a different project and key:
- **GCLOUD_TESTS_GOLANG_FIRESTORE_PROJECT_ID**: Developers Console project's ID
supporting Firestore
- **GCLOUD_TESTS_GOLANG_FIRESTORE_KEY**: The path to the JSON key file.
Install the [gcloud command-line tool][gcloudcli] to your machine and use it
to create some resources used in integration tests.
From the project's root directory:
``` sh
# Set the default project in your env.
$ gcloud config set project $GCLOUD_TESTS_GOLANG_PROJECT_ID
# Authenticate the gcloud tool with your account.
$ gcloud auth login
# Create the indexes used in the datastore integration tests.
$ gcloud preview datastore create-indexes datastore/testdata/index.yaml
# Create a Google Cloud storage bucket with the same name as your test project,
# and with the Stackdriver Logging service account as owner, for the sink
# integration tests in logging.
$ gsutil mb gs://$GCLOUD_TESTS_GOLANG_PROJECT_ID
$ gsutil acl ch -g cloud-logs@google.com:O gs://$GCLOUD_TESTS_GOLANG_PROJECT_ID
# Create a PubSub topic for integration tests of storage notifications.
$ gcloud beta pubsub topics create go-storage-notification-test
# Create a Spanner instance for the spanner integration tests.
$ gcloud beta spanner instances create go-integration-test --config regional-us-central1 --nodes 1 --description 'Instance for go client test'
# NOTE: Spanner instances are priced by the node-hour, so you may want to delete
# the instance after testing with 'gcloud beta spanner instances delete'.
```
Once you've set the environment variables, you can run the integration tests by
running:
``` sh
$ go test -v cloud.google.com/go/...
```

# Code Changes
## v0.10.0
- pubsub: Replace
```
sub.ModifyPushConfig(ctx, pubsub.PushConfig{Endpoint: "https://example.com/push"})
```
with
```
sub.Update(ctx, pubsub.SubscriptionConfigToUpdate{
PushConfig: &pubsub.PushConfig{Endpoint: "https://example.com/push"},
})
```
- trace: traceGRPCServerInterceptor will be provided from *trace.Client.
Given an initialized `*trace.Client` named `tc`, instead of
```
s := grpc.NewServer(grpc.UnaryInterceptor(trace.GRPCServerInterceptor(tc)))
```
write
```
s := grpc.NewServer(grpc.UnaryInterceptor(tc.GRPCServerInterceptor()))
```
- trace trace.GRPCClientInterceptor will also provided from *trace.Client.
Instead of
```
conn, err := grpc.Dial(srv.Addr, grpc.WithUnaryInterceptor(trace.GRPCClientInterceptor()))
```
write
```
conn, err := grpc.Dial(srv.Addr, grpc.WithUnaryInterceptor(tc.GRPCClientInterceptor()))
```
- trace: We removed the deprecated `trace.EnableGRPCTracing`. Use the gRPC
interceptor as a dial option as shown below when initializing Cloud package
clients:
```
c, err := pubsub.NewClient(ctx, "project-id", option.WithGRPCDialOption(grpc.WithUnaryInterceptor(tc.GRPCClientInterceptor())))
if err != nil {
...
}
```

Documentation and examples are available at
https://godoc.org/cloud.google.com/go
Visit or join the
[google-api-go-announce group](https://groups.google.com/forum/#!forum/google-api-go-announce)
for updates on these packages.
## Go Versions Supported
We support the two most recent major versions of Go. If Google App Engine uses
an older version, we support that as well. You can see which versions are
currently supported by looking at the lines following `go:` in
[`.travis.yml`](.travis.yml).
## Authorization
By default, each API will use [Google Application Default Credentials][default-creds]
for authorization credentials used in calling the API endpoints. This will allow your
application to run in many environments without requiring explicit configuration.
[snip]:# (auth)
```go
client, err := storage.NewClient(ctx)
```
To authorize using a
[JSON key file](https://cloud.google.com/iam/docs/managing-service-account-keys),
pass
[`option.WithServiceAccountFile`](https://godoc.org/google.golang.org/api/option#WithServiceAccountFile)
to the `NewClient` function of the desired package. For example:
[snip]:# (auth-JSON)
```go
client, err := storage.NewClient(ctx, option.WithServiceAccountFile("path/to/keyfile.json"))
```
You can exert more control over authorization by using the
[`golang.org/x/oauth2`](https://godoc.org/golang.org/x/oauth2) package to
create an `oauth2.TokenSource`. Then pass
[`option.WithTokenSource`](https://godoc.org/google.golang.org/api/option#WithTokenSource)
to the `NewClient` function:
[snip]:# (auth-ts)
```go
tokenSource := ...
client, err := storage.NewClient(ctx, option.WithTokenSource(tokenSource))
```
## Cloud Datastore [![GoDoc](https://godoc.org/cloud.google.com/go/datastore?status.svg)](https://godoc.org/cloud.google.com/go/datastore)

[snip]:# (datastore-1)
```go
client, err := datastore.NewClient(ctx, "my-project-id")
if err != nil {
log.Fatal(err)
}
```
Then use that client to interact with the API:
[snip]:# (datastore-2)
```go
type Post struct {
Title string
Body string `datastore:",noindex"`
PublishedAt time.Time
}
keys := []*datastore.Key{
datastore.NameKey("Post", "post1", nil),
datastore.NameKey("Post", "post2", nil),
}
posts := []*Post{
{Title: "Post 1", Body: "...", PublishedAt: time.Now()},
{Title: "Post 2", Body: "...", PublishedAt: time.Now()},
}
if _, err := client.PutMulti(ctx, keys, posts); err != nil {
log.Fatal(err)
}
```

if err != nil {
log.Fatal(err)
}
```
[snip]:# (storage-2)
```go
// Read the object1 from bucket.
rc, err := client.Bucket("bucket").Object("object1").NewReader(ctx)
if err != nil {
log.Fatal(err)
}
defer rc.Close()
body, err := ioutil.ReadAll(rc)
if err != nil {
log.Fatal(err)
}
```
## Cloud Pub/Sub [![GoDoc](https://godoc.org/cloud.google.com/go/pubsub?status.svg)](https://godoc.org/cloud.google.com/go/pubsub)
- [About Cloud Pubsub][cloud-pubsub]
- [API documentation][cloud-pubsub-docs]
- [Go client documentation](https://godoc.org/cloud.google.com/go/pubsub)
- [Complete sample programs](https://github.com/GoogleCloudPlatform/golang-samples/tree/master/pubsub)
### Example Usage
First create a `pubsub.Client` to use throughout your application:
[snip]:# (pubsub-1)
```go
client, err := pubsub.NewClient(ctx, "project-id")
if err != nil {
log.Fatal(err)
}
```
Then use the client to publish and subscribe:
[snip]:# (pubsub-2)
```go
// Publish "hello world" on topic1.
topic := client.Topic("topic1")
res := topic.Publish(ctx, &pubsub.Message{
Data: []byte("hello world"),
})
// The publish happens asynchronously.
// Later, you can get the result from res:
...
msgID, err := res.Get(ctx)
if err != nil {
log.Fatal(err)
}
// Use a callback to receive messages via subscription1.
sub := client.Subscription("subscription1")
err = sub.Receive(ctx, func(ctx context.Context, m *pubsub.Message) {
fmt.Println(m.Data)
m.Ack() // Acknowledge that we've consumed the message.
})
if err != nil {
log.Println(err)
}
```
## Cloud BigQuery [![GoDoc](https://godoc.org/cloud.google.com/go/bigquery?status.svg)](https://godoc.org/cloud.google.com/go/bigquery)
- [About Cloud BigQuery][cloud-bigquery]
- [API documentation][cloud-bigquery-docs]
- [Go client documentation][cloud-bigquery-ref]
- [Complete sample programs](https://github.com/GoogleCloudPlatform/golang-samples/tree/master/bigquery)
### Example Usage
First create a `bigquery.Client` to use throughout your application:
[snip]:# (bq-1)
```go
c, err := bigquery.NewClient(ctx, "my-project-ID")
if err != nil {
// TODO: Handle error.
}
```
Then use that client to interact with the API:
[snip]:# (bq-2)
```go
// Construct a query.
q := c.Query(`
SELECT year, SUM(number)
FROM [bigquery-public-data:usa_names.usa_1910_2013]
WHERE name = "William"
GROUP BY year
ORDER BY year
`)
// Execute the query.
it, err := q.Read(ctx)
if err != nil {
// TODO: Handle error.
}
// Iterate through the results.
for {
var values []bigquery.Value
err := it.Next(&values)
if err == iterator.Done {
break
}
if err != nil {
// TODO: Handle error.
}
fmt.Println(values)
}
```

[snip]:# (logging-1)
```go
ctx := context.Background()
client, err := logging.NewClient(ctx, "my-project")
if err != nil {
// TODO: Handle error.
}
```
Usually, you'll want to add log entries to a buffer to be periodically flushed
(automatically and asynchronously) to the Stackdriver Logging service.
[snip]:# (logging-2)
```go
logger := client.Logger("my-log")
logger.Log(logging.Entry{Payload: "something happened!"})
```
Close your client before your program exits, to flush any buffered log entries.
[snip]:# (logging-3)
```go
err = client.Close()
if err != nil {
// TODO: Handle error.
}
```

# BigQuery Benchmark
This directory contains benchmarks for BigQuery client.
## Usage
`go run bench.go -- <your project id> queries.json`
BigQuery service caches requests so the benchmark should be run
at least twice, disregarding the first result.

/*
Package bigquery provides a client for the BigQuery service.
Note: This package is in beta. Some backwards-incompatible changes may occur.
The following assumes a basic familiarity with BigQuery concepts.
See https://cloud.google.com/bigquery/docs.
Creating a Client
To start working with this package, create a client:
ctx := context.Background()
client, err := bigquery.NewClient(ctx, projectID)
if err != nil {
// TODO: Handle error.
}
Querying
To query existing tables, create a Query and call its Read method:
q := client.Query(`
SELECT year, SUM(number) as num
FROM [bigquery-public-data:usa_names.usa_1910_2013]
WHERE name = "William"
GROUP BY year
ORDER BY year
`)
it, err := q.Read(ctx)
if err != nil {
// TODO: Handle error.
}
Then iterate through the resulting rows. You can store a row using
anything that implements the ValueLoader interface, or with a slice or map of bigquery.Value.
A slice is simplest:
for {
var values []bigquery.Value
err := it.Next(&values)
if err == iterator.Done {
break
}
if err != nil {
// TODO: Handle error.
}
fmt.Println(values)
}
You can also use a struct whose exported fields match the query:
type Count struct {
Year int
Num int
}
for {
var c Count
err := it.Next(&c)
if err == iterator.Done {
break
}
if err != nil {
// TODO: Handle error.
}
fmt.Println(c)
}
You can also start the query running and get the results later.
Create the query as above, but call Run instead of Read. This returns a Job,
which represents an asychronous operation.
job, err := q.Run(ctx)
if err != nil {
// TODO: Handle error.
}
Get the job's ID, a printable string. You can save this string to retrieve
the results at a later time, even in another process.
jobID := job.ID()
fmt.Printf("The job ID is %s\n", jobID)
To retrieve the job's results from the ID, first look up the Job:
job, err = client.JobFromID(ctx, jobID)
if err != nil {
// TODO: Handle error.
}
Use the Job.Read method to obtain an iterator, and loop over the rows.
Query.Read is just a convenience method that combines Query.Run and Job.Read.
it, err = job.Read(ctx)
if err != nil {
// TODO: Handle error.
}
// Proceed with iteration as above.
Datasets and Tables
You can refer to datasets in the client's project with the Dataset method, and
in other projects with the DatasetInProject method:
myDataset := client.Dataset("my_dataset")
yourDataset := client.DatasetInProject("your-project-id", "your_dataset")
These methods create references to datasets, not the datasets themselves. You can have
a dataset reference even if the dataset doesn't exist yet. Use Dataset.Create to
create a dataset from a reference:
if err := myDataset.Create(ctx, nil); err != nil {
// TODO: Handle error.
}
You can refer to tables with Dataset.Table. Like bigquery.Dataset, bigquery.Table is a reference
to an object in BigQuery that may or may not exist.
table := myDataset.Table("my_table")
You can create, delete and update the metadata of tables with methods on Table.
For instance, you could create a temporary table with:
err = myDataset.Table("temp").Create(ctx, &bigquery.TableMetadata{
ExpirationTime: time.Now().Add(1*time.Hour)})
if err != nil {
// TODO: Handle error.
}
We'll see how to create a table with a schema in the next section.
Schemas
There are two ways to construct schemas with this package.
You can build a schema by hand, like so:
schema1 := bigquery.Schema{
{Name: "Name", Required: true, Type: bigquery.StringFieldType},
{Name: "Grades", Repeated: true, Type: bigquery.IntegerFieldType},
{Name: "Optional", Required: false, Type: bigquery.IntegerFieldType},
}
Or you can infer the schema from a struct:
type student struct {
Name string
Grades []int
Optional bigquery.NullInt64
}
schema2, err := bigquery.InferSchema(student{})
if err != nil {
// TODO: Handle error.
}
// schema1 and schema2 are identical.
Struct inference supports tags like those of the encoding/json package, so you can
change names, ignore fields, or mark a field as nullable (non-required). Fields
declared as on of the Null types (NullInt64, NullFloat64, NullString, NullBool,
NullTimestamp, NullDate, NullTime and NullDateTime) are automatically inferred as
nullable, so the "nullable" tag is only needed for []byte and pointer-to-struct
fields.
type student2 struct {
Name string `bigquery:"full_name"`
Grades []int
Secret string `bigquery:"-"`
Optional []byte `bigquery:",nullable"
}
schema3, err := bigquery.InferSchema(student2{})
if err != nil {
// TODO: Handle error.
}
// schema3 has required fields "full_name" and "Grade", and nullable BYTES field "Optional".
Having constructed a schema, you can create a table with it like so:
if err := table.Create(ctx, &bigquery.TableMetadata{Schema: schema1}); err != nil {
// TODO: Handle error.
}
Copying
You can copy one or more tables to another table. Begin by constructing a Copier
describing the copy. Then set any desired copy options, and finally call Run to get a Job:
copier := myDataset.Table("dest").CopierFrom(myDataset.Table("src"))
copier.WriteDisposition = bigquery.WriteTruncate
job, err = copier.Run(ctx)
if err != nil {
// TODO: Handle error.
}
You can chain the call to Run if you don't want to set options:
job, err = myDataset.Table("dest").CopierFrom(myDataset.Table("src")).Run(ctx)
if err != nil {
// TODO: Handle error.
}
You can wait for your job to complete:
status, err := job.Wait(ctx)
if err != nil {
// TODO: Handle error.
}
Job.Wait polls with exponential backoff. You can also poll yourself, if you
wish:
for {
status, err := job.Status(ctx)
if err != nil {
// TODO: Handle error.
}
if status.Done() {
if status.Err() != nil {
log.Fatalf("Job failed with error %v", status.Err())
}
break
}
time.Sleep(pollInterval)
}
Loading and Uploading
There are two ways to populate a table with this package: load the data from a Google Cloud Storage
object, or upload rows directly from your program.
For loading, first create a GCSReference, configuring it if desired. Then make a Loader, optionally configure
it as well, and call its Run method.
gcsRef := bigquery.NewGCSReference("gs://my-bucket/my-object")
gcsRef.AllowJaggedRows = true
loader := myDataset.Table("dest").LoaderFrom(gcsRef)
loader.CreateDisposition = bigquery.CreateNever
job, err = loader.Run(ctx)
// Poll the job for completion if desired, as above.
To upload, first define a type that implements the ValueSaver interface, which has a single method named Save.
Then create an Uploader, and call its Put method with a slice of values.
u := table.Uploader()
// Item implements the ValueSaver interface.
items := []*Item{
{Name: "n1", Size: 32.6, Count: 7},
{Name: "n2", Size: 4, Count: 2},
{Name: "n3", Size: 101.5, Count: 1},
}
if err := u.Put(ctx, items); err != nil {
// TODO: Handle error.
}
You can also upload a struct that doesn't implement ValueSaver. Use the StructSaver type
to specify the schema and insert ID by hand, or just supply the struct or struct pointer
directly and the schema will be inferred:
type Item2 struct {
Name string
Size float64
Count int
}
// Item implements the ValueSaver interface.
items2 := []*Item2{
{Name: "n1", Size: 32.6, Count: 7},
{Name: "n2", Size: 4, Count: 2},
{Name: "n3", Size: 101.5, Count: 1},
}
if err := u.Put(ctx, items2); err != nil {
// TODO: Handle error.
}
Extracting
If you've been following so far, extracting data from a BigQuery table
into a Google Cloud Storage object will feel familiar. First create an
Extractor, then optionally configure it, and lastly call its Run method.
extractor := table.ExtractorTo(gcsRef)
extractor.DisableHeader = true
job, err = extractor.Run(ctx)
// Poll the job for completion if desired, as above.

Cbt is a tool for doing basic interactions with Cloud Bigtable. To learn how to
install the cbt tool, see the
[cbt overview](https://cloud.google.com/bigtable/docs/go/cbt-overview).
Usage:
cbt [options] command [arguments]
The commands are:
count Count rows in a table
createinstance Create an instance with an initial cluster
createcluster Create a cluster in the configured instance (replication alpha)
createfamily Create a column family
createtable Create a table
updatecluster Update a cluster in the configured instance
deleteinstance Deletes an instance
deletecluster Deletes a cluster from the configured instance (replication alpha)
deletecolumn Delete all cells in a column
deletefamily Delete a column family
deleterow Delete a row
deletetable Delete a table
doc Print godoc-suitable documentation for cbt
help Print help text
listinstances List instances in a project
listclusters List instances in an instance
lookup Read from a single row
ls List tables and column families
mddoc Print documentation for cbt in Markdown format
read Read rows
set Set value of a cell
setgcpolicy Set the GC policy for a column family
waitforreplication Blocks until all the completed writes have been replicated to all the clusters (replication alpha)
version Print the current cbt version
Use "cbt help <command>" for more information about a command.
The options are:
-project string
project ID, if unset uses gcloud configured project
-instance string
Cloud Bigtable instance
-creds string
if set, use application credentials in this file
Alpha features are not currently available to most Cloud Bigtable customers. The
features might be changed in backward-incompatible ways and are not recommended
for production use. They are not subject to any SLA or deprecation policy.
For convenience, values of the -project, -instance, -creds,
-admin-endpoint and -data-endpoint flags may be specified in
/usr/local/google/home/igorbernstein/.cbtrc in this format:
project = my-project-123
instance = my-instance
creds = path-to-account-key.json
admin-endpoint = hostname:port
data-endpoint = hostname:port
All values are optional, and all will be overridden by flags.

Package bigtable is an API to Google Cloud Bigtable.
See https://cloud.google.com/bigtable/docs/ for general product documentation.
Setup and Credentials
Use NewClient or NewAdminClient to create a client that can be used to access
the data or admin APIs respectively. Both require credentials that have permission
to access the Cloud Bigtable API.
If your program is run on Google App Engine or Google Compute Engine, using the Application Default Credentials
(https://developers.google.com/accounts/docs/application-default-credentials)
is the simplest option. Those credentials will be used by default when NewClient or NewAdminClient are called.
To use alternate credentials, pass them to NewClient or NewAdminClient using option.WithTokenSource.
For instance, you can use service account credentials by visiting
https://cloud.google.com/console/project/MYPROJECT/apiui/credential,
creating a new OAuth "Client ID", storing the JSON key somewhere accessible, and writing
jsonKey, err := ioutil.ReadFile(pathToKeyFile)
...
config, err := google.JWTConfigFromJSON(jsonKey, bigtable.Scope) // or bigtable.AdminScope, etc.
...
client, err := bigtable.NewClient(ctx, project, instance, option.WithTokenSource(config.TokenSource(ctx)))
...
Here, `google` means the golang.org/x/oauth2/google package
and `option` means the google.golang.org/api/option package.
Reading
The principal way to read from a Bigtable is to use the ReadRows method on *Table.
A RowRange specifies a contiguous portion of a table. A Filter may be provided through
RowFilter to limit or transform the data that is returned.
tbl := client.Open("mytable")
...
// Read all the rows starting with "com.google.",
// but only fetch the columns in the "links" family.
rr := bigtable.PrefixRange("com.google.")
err := tbl.ReadRows(ctx, rr, func(r Row) bool {
// do something with r
return true // keep going
}, bigtable.RowFilter(bigtable.FamilyFilter("links")))
...
To read a single row, use the ReadRow helper method.
r, err := tbl.ReadRow(ctx, "com.google.cloud") // "com.google.cloud" is the entire row key
...
Writing
This API exposes two distinct forms of writing to a Bigtable: a Mutation and a ReadModifyWrite.
The former expresses idempotent operations.
The latter expresses non-idempotent operations and returns the new values of updated cells.
These operations are performed by creating a Mutation or ReadModifyWrite (with NewMutation or NewReadModifyWrite),
building up one or more operations on that, and then using the Apply or ApplyReadModifyWrite
methods on a Table.
For instance, to set a couple of cells in a table,
tbl := client.Open("mytable")
mut := bigtable.NewMutation()
mut.Set("links", "maps.google.com", bigtable.Now(), []byte("1"))
mut.Set("links", "golang.org", bigtable.Now(), []byte("1"))
err := tbl.Apply(ctx, "com.google.cloud", mut)
...
To increment an encoded value in one cell,
tbl := client.Open("mytable")
rmw := bigtable.NewReadModifyWrite()
rmw.Increment("links", "golang.org", 12) // add 12 to the cell in column "links:golang.org"
r, err := tbl.ApplyReadModifyWrite(ctx, "com.google.cloud", rmw)
...
Retries
If a read or write operation encounters a transient error it will be retried until a successful
response, an unretryable error or the context deadline is reached. Non-idempotent writes (where
the timestamp is set to ServerTime) will not be retried. In the case of ReadRows, retried calls
will not re-scan rows that have already been processed.
Authentication
See examples of authorization and authentication at
https://godoc.org/cloud.google.com/go#pkg-examples.
*/
package bigtable // import "cloud.google.com/go/bigtable"
// Scope constants for authentication credentials.
// These should be used when using credential creation functions such as oauth.NewServiceAccountFromFile.

// ReadonlyScope is the OAuth scope for Cloud Bigtable read-only data operations.

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 (bigquery, compute, storage, and translate) 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 (all others in this repo), connection pooling is configurable. 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.
