Google Cloud Dataplex V1 Client - Class MetadataServiceClient (0.16.0)

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 provides the ability to make remote calls to the backing service through method calls that map to API methods.

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.

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\MetadataServiceClient::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

 *                                        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:

 *                                        - 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.

 *                                        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.
 *

 *                                        schema. This setting guarantees that Dataplex will not
 *                                        change schema fields.
