Google Cloud Ai Platform V1 Client - Class FeaturestoreOnlineServingServiceClient (0.10.0)

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

Service Description: A service for serving online feature values.

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:

$featurestoreOnlineServingServiceClient = new FeaturestoreOnlineServingServiceClient();
try {
    $formattedEntityType = $featurestoreOnlineServingServiceClient->entityTypeName('[PROJECT]', '[LOCATION]', '[FEATURESTORE]', '[ENTITY_TYPE]');
    $entityId = 'entity_id';
    $featureSelector = new FeatureSelector();
    $response = $featurestoreOnlineServingServiceClient->readFeatureValues($formattedEntityType, $entityId, $featureSelector);
} finally {
    $featurestoreOnlineServingServiceClient->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

entityTypeName

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

Parameters
Name	Description
`project`	`string`
`location`	`string`
`featurestore`	`string`
`entityType`	`string`

Returns
Type	Description
`string`	The formatted entity_type 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

entityType: projects/{project}/locations/{location}/featurestores/{featurestore}/entityTypes/{entity_type}

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 {@see} object or {@see} 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 {@see} .
`↳ 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 {@see} 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 {@see} and {@see} 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.
