Google Cloud Dataplex V1 Client - Class MetadataServiceClient (0.7.0)

Reference documentation and code samples for the Google Cloud Dataplex V1 Client class MetadataServiceClient.

Service Description: Metadata service manages metadata resources such as tables, filesets and partitions.

This class is currently experimental and may be subject to changes.

Namespace

Google \ Cloud \ Dataplex \ V1 \ Client

Methods

__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.

createEntity

Create a metadata entity.

The async variant is Google\Cloud\Dataplex\V1\Client\BaseClient\self::createEntityAsync() .

Parameters
Name	Description
`request`	`Google\Cloud\Dataplex\V1\CreateEntityRequest` A request to house fields associated with the call.
`callOptions`	`array` Optional.
`↳ retrySettings`	`RetrySettings\|array` Retry settings to use for this call. Can be a Google\ApiCore\RetrySettings object, or an associative array of retry settings parameters. See the documentation on Google\ApiCore\RetrySettings for example usage.

Returns
Type	Description

/**
 * @param string $formattedParent         The resource name of the parent zone:

 * @param string $entityId                A user-provided entity ID. It is mutable, and will be used as the
 *                                        published table name. Specifying a new ID in an update entity
 *                                        request will override the existing value.
 *                                        The ID must contain only letters (a-z, A-Z), numbers (0-9), and

 *                                        location containing the entity data. The entity must be with in the same

 * @param string $entityDataPath          Immutable. The storage path of the entity data.
 *                                        For Cloud Storage data, this is the fully-qualified path to the entity,
 *                                        such as `gs://bucket/path/to/data`. For BigQuery data, this is the name of

 *                                        `projects/project_id/datasets/dataset_id/tables/table_id`.
 * @param int    $entitySystem            Immutable. Identifies the storage system of the entity data.
 * @param string $entityFormatMimeType    The mime type descriptor for the data. Must match the pattern
 *                                        {type}/{subtype}. Supported values:

 *                                        - video/{video subtype}
 *                                        - audio/{audio subtype}
 * @param bool   $entitySchemaUserManaged Set to `true` if user-managed or `false` if managed by Dataplex.
 *                                        The default is `false` (managed by Dataplex).
 *
 *                                        - Set to `false`to enable Dataplex discovery to update the schema.
 *                                        including new data discovery, schema inference, and schema evolution.
 *                                        Users retain the ability to input and edit the schema. Dataplex
 *                                        treats schema input by the user as though produced
 *                                        by a previous Dataplex discovery operation, and it will
 *                                        evolve the schema and take action based on that treatment.
 *
 *                                        - Set to `true` to fully manage the entity
 *                                        schema. This setting guarantees that Dataplex will not
 *                                        change schema fields.

 *                                        Users retain the ability to input and edit the schema. Dataplex
 *                                        treats schema input by the user as though produced
 *                                        by a previous Dataplex discovery operation, and it will
 *                                        evolve the schema and take action based on that treatment.
 *
 *                                        - Set to `true` to fully manage the entity
 *                                        schema. This setting guarantees that Dataplex will not
 *                                        change schema fields.
