Package connection is an auto-generated package for the BigQuery Connection API.
Allows users to manage BigQuery connections to external data sources.
NOTE: This package is in beta. It is not stable, and may be subject to changes.
General documentation
For information that is relevant for all client libraries please reference https://pkg.go.dev/cloud.google.com/go#pkg-overview. Some information on this page includes:
- Authentication and Authorization
- Timeouts and Cancellation
- Testing against Client Libraries
- Debugging Client Libraries
- Inspecting errors
Example usage
To get started with this package, create a client.
ctx := context.Background() // This snippet has been automatically generated and should be regarded as a code template only. // It will require modifications to work: // - It may require correct/in-range values for request initialization. // - It may require specifying regional endpoints when creating the service client as shown in: // https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options c, err := connection.NewClient(ctx) if err != nil { // TODO: Handle error. } defer c.Close()
The client will use your default application credentials. Clients should be reused instead of created as needed. The methods of Client are safe for concurrent use by multiple goroutines. The returned client must be Closed when it is done being used.
Using the Client
The following is an example of making an API call with the newly created client.
ctx := context.Background() // This snippet has been automatically generated and should be regarded as a code template only. // It will require modifications to work: // - It may require correct/in-range values for request initialization. // - It may require specifying regional endpoints when creating the service client as shown in: // https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options c, err := connection.NewClient(ctx) if err != nil { // TODO: Handle error. } defer c.Close() req := &connectionpb.CreateConnectionRequest{ // TODO: Fill request struct fields. // See https://pkg.go.dev/cloud.google.com/go/bigquery/connection/apiv1beta1/connectionpb#CreateConnectionRequest. } resp, err := c.CreateConnection(ctx, req) if err != nil { // TODO: Handle error. } // TODO: Use resp. _ = resp
Use of Context
The ctx passed to NewClient is used for authentication requests and for creating the underlying connection, but is not used for subsequent calls. Individual methods on the client use the ctx given to them.
To close the open connection, use the Close() method.
Functions
func DefaultAuthScopes
func DefaultAuthScopes() []string
DefaultAuthScopes reports the default set of authentication scopes to use with this package.
CallOptions
type CallOptions struct {
CreateConnection []gax.CallOption
GetConnection []gax.CallOption
ListConnections []gax.CallOption
UpdateConnection []gax.CallOption
UpdateConnectionCredential []gax.CallOption
DeleteConnection []gax.CallOption
GetIamPolicy []gax.CallOption
SetIamPolicy []gax.CallOption
TestIamPermissions []gax.CallOption
}
CallOptions contains the retry settings for each method of Client.
Client
type Client struct {
// The call options for this service.
CallOptions *CallOptions
// contains filtered or unexported fields
}
Client is a client for interacting with BigQuery Connection API. Methods, except Close, may be called concurrently. However, fields must not be modified concurrently with method calls.
Manages external data source connections and credentials.
func NewClient
NewClient creates a new connection service client based on gRPC. The returned client must be Closed when it is done being used to clean up its underlying connections.
Manages external data source connections and credentials.
Example
package main
import (
"context"
connection "cloud.google.com/go/bigquery/connection/apiv1beta1"
)
func main() {
ctx := context.Background()
// This snippet has been automatically generated and should be regarded as a code template only.
// It will require modifications to work:
// - It may require correct/in-range values for request initialization.
// - It may require specifying regional endpoints when creating the service client as shown in:
// https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options
c, err := connection.NewClient(ctx)
if err != nil {
// TODO: Handle error.
}
defer c.Close()
// TODO: Use client.
_ = c
}
func NewRESTClient
NewRESTClient creates a new connection service rest client.
Manages external data source connections and credentials.
Example
package main
import (
"context"
connection "cloud.google.com/go/bigquery/connection/apiv1beta1"
)
func main() {
ctx := context.Background()
// This snippet has been automatically generated and should be regarded as a code template only.
// It will require modifications to work:

// - It may require specifying regional endpoints when creating the service client as shown in:
// https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options

if err != nil {
// TODO: Handle error.
}
defer c.Close()
// TODO: Use client.
_ = c
}
func (*Client) Close
Close closes the connection to the API service. The user should invoke this when the client is no longer required.
func (*Client) Connection (deprecated)
func (c *Client) Connection() *grpc.ClientConn
Connection returns a connection to the API service.
Deprecated: Connections are now pooled so this method does not always return the same resource.
func (*Client) CreateConnection
func (c *Client) CreateConnection(ctx context.Context, req *connectionpb.CreateConnectionRequest, opts ...gax.CallOption) (*connectionpb.Connection, error)

TestIamPermissions returns permissions that a caller has on the specified resource. If the resource does not exist, this will return an empty set of permissions, not a NOT_FOUND error.
Note: This operation is designed to be used for building permission-aware UIs and command-line tools, not for authorization checking. This operation may “fail open” without warning.
