Google Cloud Ai Platform V1 Client - Class MetadataServiceClient (0.15.0)

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

Service Description: Service for reading and writing metadata entries.

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:

$metadataServiceClient = new MetadataServiceClient();
try {
    $formattedContext = $metadataServiceClient->contextName('[PROJECT]', '[LOCATION]', '[METADATA_STORE]', '[CONTEXT]');
    $response = $metadataServiceClient->addContextArtifactsAndExecutions($formattedContext);
} finally {
    $metadataServiceClient->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.

__construct

Constructor.

Parameters
NameDescription
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.

optionalArgs array

Optional.

↳ pageSize int

The maximum number of resources contained in the underlying API response. The API may return fewer values in a page, even if there are additional values to be retrieved.

↳ pageToken string

A page token is used to specify a page of values to be returned. If no page token is specified (the default), the first page of values will be returned. Any page token used here must have been generated by a previous call to the API.

↳ filter string

Filter specifying the boolean condition for the Artifacts to satisfy in order to be part of the result set. The syntax to define filter query is based on https://google.aip.dev/160. The supported set of filters include the following: * Attribute filtering: For example: display_name = "test". Supported fields include: name, display_name, uri, state, schema_title, create_time, and update_time. Time fields, such as create_time and update_time, require values specified in RFC-3339 format. For example: create_time = "2020-11-19T11:30:00-04:00" * Metadata field: To filter on metadata fields use traversal operation as follows: metadata.<field_name>.<type_value>. For example: metadata.field_1.number_value = 10.0 * Context based filtering: To filter Artifacts based on the contexts to which they belong, use the function operator with the full resource name in_context(<context-name>). For example: in_context("projects/<project_number>/locations/<location>/metadataStores/<metadatastore_name>/contexts/<context-id>") Each of the above supported filter types can be combined together using logical operators (AND & OR). Maximum nested expression depth allowed is 5. For example: display_name = "test" AND metadata.field1.bool_value = true.

↳ orderBy string

How the list of messages is ordered. Specify the values to order by and an ordering operation. The default sorting order is ascending. To specify descending order for a field, users append a " desc" suffix; for example: "foo desc, bar". Subfields are specified with a . character, such as foo.bar. see https://google.aip.dev/132#ordering for more details.

↳ 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.

queryArtifactLineageSubgraph

Retrieves lineage of an Artifact represented through Artifacts and Executions connected by Event edges and returned as a LineageSubgraph.

Parameters
NameDescription
artifact string

Required. The resource name of the Artifact whose Lineage needs to be retrieved as a LineageSubgraph. Format: projects/{project}/locations/{location}/metadataStores/{metadatastore}/artifacts/{artifact}

The request may error with FAILED_PRECONDITION if the number of Artifacts, the number of Executions, or the number of Events that would be returned for the Context exceeds 1000.

optionalArgs array

Optional.

↳ maxHops int

Specifies the size of the lineage graph in terms of number of hops from the specified artifact. Negative Value: INVALID_ARGUMENT error is returned 0: Only input artifact is returned. No value: Transitive closure is performed to return the complete graph.

↳ filter string

Filter specifying the boolean condition for the Artifacts to satisfy in order to be part of the Lineage Subgraph. The syntax to define filter query is based on https://google.aip.dev/160. The supported set of filters include the following: * Attribute filtering: For example: display_name = "test" Supported fields include: name, display_name, uri, state, schema_title, create_time, and update_time. Time fields, such as create_time and update_time, require values specified in RFC-3339 format. For example: create_time = "2020-11-19T11:30:00-04:00" * Metadata field: To filter on metadata fields use traversal operation as follows: metadata.<field_name>.<type_value>. For example: metadata.field_1.number_value = 10.0 Each of the above supported filter types can be combined together using logical operators (AND & OR). Maximum nested expression depth allowed is 5. For example: display_name = "test" AND metadata.field1.bool_value = true.

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.

Parameters
NameDescription
resource string

REQUIRED: The resource for which the policy detail is being requested. See the operation documentation for the appropriate value for this field.

permissions string[]

The set of permissions to check for the resource. Permissions with wildcards (such as '' or 'storage.') are not allowed. For more information see IAM Overview.

optionalArgs array
