/**
 * Service Description: The service that handles CRUD and List for resources for Featurestore.
 *
 * 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:
 *
 * ```
 * $featurestoreServiceClient = new FeaturestoreServiceClient();
 * try {
 *     $formattedParent = $featurestoreServiceClient->entityTypeName('[PROJECT]', '[LOCATION]', '[FEATURESTORE]', '[ENTITY_TYPE]');
 *     $requests = [];
 *     $operationResponse = $featurestoreServiceClient->batchCreateFeatures($formattedParent, $requests);
 *     $operationResponse->pollUntilComplete();
 *     if ($operationResponse->operationSucceeded()) {
 *         $result = $operationResponse->getResult();
 *     // doSomethingWith($result)
 *     } else {
 *         $error = $operationResponse->getError();
 *         // handleError($error)
 *     }
 *     // Alternatively:
 *     // start the operation, keep the operation name, and resume later
 *     $operationResponse = $featurestoreServiceClient->batchCreateFeatures($formattedParent, $requests);
 *     $operationName = $operationResponse->getName();
 *     // ... do other work
 *     $newOperationResponse = $featurestoreServiceClient->resumeOperation($operationName, 'batchCreateFeatures');
 *     while (!$newOperationResponse->isDone()) {
 *         // ... do other work
 *         $newOperationResponse->reload();
 *     }
 *     if ($newOperationResponse->operationSucceeded()) {
 *         $result = $newOperationResponse->getResult();
 *     // doSomethingWith($result)
 *     } else {
 *         $error = $newOperationResponse->getError();
 *         // handleError($error)
 *     }
 * } finally {
 *     $featurestoreServiceClient->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.

     * values of each read instance as of each instance's read timestamp.

     *     @type BigQuerySource $bigqueryReadInstances
     *           Similar to csv_read_instances, but from BigQuery source.
     *     @type PassThroughField[] $passThroughFields
     *           When not empty, the specified fields in the *_read_instances source will be
     *           joined as-is in the output, in addition to those fields from the

     *
     *           For BigQuery source, the type of the pass-through values will be

     *           Query string that is a conjunction of field-restricted queries and/or
     *           field-restricted filters.  Field-restricted queries and filters can be
     *           combined using `AND` to form a conjunction.
     *
     *           A field query is in the form FIELD:QUERY. This implicitly checks if QUERY
     *           exists as a substring within Feature's FIELD. The QUERY
     *           and the FIELD are converted to a sequence of words (i.e. tokens) for
     *           comparison. This is done by:
     *
     *           * Removing leading/trailing whitespace and tokenizing the search value.
     *           Characters that are not one of alphanumeric `[a-zA-Z0-9]`, underscore
     *           `_`, or asterisk `*` are treated as delimiters for tokens. `*` is treated
     *           as a wildcard that matches characters within a token.
     *           * Ignoring case.
     *           * Prepending an asterisk to the first and appending an asterisk to the
     *           last token in QUERY.
     *
     *           A QUERY must be either a singular token or a phrase. A phrase is one or
     *           multiple words enclosed in double quotation marks ("). With phrases, the
     *           order of the words is important. Words in the phrase must be matching in
     *           order and consecutively.
     *
     *           Supported FIELDs for field-restricted queries:
     *
     *           * `feature_id`
     *           * `description`
     *           * `entity_type_id`
     *
     *           Examples:
     *
     *           * `feature_id: foo` --> Matches a Feature with ID containing the substring
     *           `foo` (eg. `foo`, `foofeature`, `barfoo`).
     *           * `feature_id: foo*feature` --> Matches a Feature with ID containing the
     *           substring `foo*feature` (eg. `foobarfeature`).
     *           * `feature_id: foo AND description: bar` --> Matches a Feature with ID
     *           containing the substring `foo` and description containing the substring
     *           `bar`.
     *
     *
     *           Besides field queries, the following exact-match filters are
     *           supported. The exact-match filters do not support wildcards. Unlike
     *           field-restricted queries, exact-match filters are case-sensitive.
     *
     *           * `feature_id`: Supports = comparisons.
     *           * `description`: Supports = comparisons. Multi-token filters should be
     *           enclosed in quotes.
     *           * `entity_type_id`: Supports = comparisons.
     *           * `value_type`: Supports = and != comparisons.
     *           * `labels`: Supports key-value equality as well as key presence.
     *           * `featurestore_id`: Supports = comparisons.
     *
     *           Examples:
     *           * `description = "foo bar"` --> Any Feature with description exactly equal
     *           to `foo bar`
     *           * `value_type = DOUBLE` --> Features whose type is DOUBLE.
     *           * `labels.active = yes AND labels.env = prod` --> Features having both
     *           (active: yes) and (env: prod) labels.
