Google Cloud BigQuery Migration V2 Client - Class MigrationServiceClient (0.2.2)

Reference documentation and code samples for the Google Cloud BigQuery Migration V2 Client class MigrationServiceClient.

Service Description: Service to handle EDW migrations.

This class provides the ability to make remote calls to the backing service through method calls that map to API methods. Sample code to get started:

 $migrationServiceClient = new MigrationServiceClient();
try {
    $formattedParent = $migrationServiceClient->locationName('[PROJECT]', '[LOCATION]');
    $migrationWorkflow = new MigrationWorkflow();
    $response = $migrationServiceClient->createMigrationWorkflow($formattedParent, $migrationWorkflow);
} finally {
    $migrationServiceClient->close();
} 

Many parameters require resource names to be formatted in a particular way. To assist with these names, this class includes a format method for each type of name, and additionally a parseName method to extract the individual identifiers contained within formatted names that are returned by the API.

Methods

locationName

Formats a string containing the fully-qualified path to represent a location resource.

Parameters
Name
Description
project
string
location
string
Returns
Type
Description
string
The formatted location resource.

migrationSubtaskName

Formats a string containing the fully-qualified path to represent a migration_subtask resource.

Parameters
Name
Description
project
string
location
string
workflow
string
subtask
string
Returns
Type
Description
string
The formatted migration_subtask resource.

migrationWorkflowName

Formats a string containing the fully-qualified path to represent a migration_workflow resource.

Parameters
Name
Description
project
string
location
string
workflow
string
Returns
Type
Description
string
The formatted migration_workflow resource.

parseName

Parses a formatted name string and returns an associative array of the components in the name.

The following name formats are supported: Template: Pattern

  • location: projects/{project}/locations/{location}
  • migrationSubtask: projects/{project}/locations/{location}/workflows/{workflow}/subtasks/{subtask}
  • migrationWorkflow: projects/{project}/locations/{location}/workflows/{workflow}

The optional $template argument can be supplied to specify a particular pattern, and must match one of the templates listed above. If no $template argument is provided, or if the $template argument does not match one of the templates listed, then parseName will check each of the supported templates, and return the first match.

Parameters
Name
Description
formattedName
string

The formatted name string

template
string

Optional name of template to match

Returns
Type
Description
array
An associative array from name component IDs to component values.

__construct

Constructor.

Parameters
Name
Description
options
array

Optional. Options for configuring the service API wrapper.

↳ apiEndpoint
string

The address of the API remote host. May optionally include the port, formatted as "

↳ credentials
string|array|FetchAuthTokenInterface|CredentialsWrapper

The credentials to be used by the client to authorize API calls. This option accepts either a path to a credentials file, or a decoded credentials file as a PHP array. Advanced usage : In addition, this option can also accept a pre-constructed Google\Auth\FetchAuthTokenInterface object or Google\ApiCore\CredentialsWrapper object. Note that when one of these objects are provided, any settings in $credentialsConfig will be ignored.

↳ credentialsConfig
array

Options used to configure credentials, including auth token caching, for the client. For a full list of supporting configuration options, see Google\ApiCore\CredentialsWrapper::build() .

↳ disableRetries
bool

Determines whether or not retries defined by the client configuration should be disabled. Defaults to false .

↳ clientConfig
string|array

Client method configuration, including retry settings. This option can be either a path to a JSON file, or a PHP array containing the decoded JSON data. By default this settings points to the default client config file, which is provided in the resources folder.

↳ transport
string|TransportInterface

The transport used for executing network requests. May be either the string rest or grpc . Defaults to grpc if gRPC support is detected on the system. Advanced usage : Additionally, it is possible to pass in an already instantiated Google\ApiCore\Transport\TransportInterface object. Note that when this object is provided, any settings in $transportConfig, and any $apiEndpoint setting, will be ignored.

↳ transportConfig
array

Configuration options that will be used to construct the transport. Options for each supported transport type should be passed in a key for that transport. For example: $transportConfig = [ 'grpc' => [...], 'rest' => [...], ]; See the Google\ApiCore\Transport\GrpcTransport::build() and Google\ApiCore\Transport\RestTransport::build() methods for the supported options.

↳ clientCertSource
callable

A callable which returns the client cert as a string. This can be used to provide a certificate and private key to the transport layer for mTLS.
