Cloud Firestore V1 Client - Class FirestoreClient (1.27.3)

Reference documentation and code samples for the Cloud Firestore V1 Client class FirestoreClient.

Service Description: The Cloud Firestore service.

Cloud Firestore is a fast, fully managed, serverless, cloud-native NoSQL document database that simplifies storing, syncing, and querying data for your mobile, web, and IoT apps at global scale. Its client libraries provide live synchronization and offline support, while its security features and integrations with Firebase and Google Cloud Platform (GCP) accelerate building truly serverless apps.

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:

$firestoreClient = new FirestoreClient();
try {
    $database = 'database';
    $documents = [];
    // Read all responses until the stream is complete
    $stream = $firestoreClient->batchGetDocuments($database, $documents);
    foreach ($stream->readAll() as $element) {
        // doSomethingWith($element);
    }
} finally {
    $firestoreClient->close();
}

`↳ 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.

`↳ 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.

partitionQueryPaginated

Partitions a query by returning partition cursors that can be used to run the query in parallel. The returned partition cursors are split points that can be used by RunQuery as starting/end points for the query results.

Sample code:

$firestoreClient = new FirestoreClient();
try {
    // Iterate over pages of elements
    $pagedResponse = $firestoreClient->partitionQueryPaginated();
    foreach ($pagedResponse->iteratePages() as $page) {
        foreach ($page as $element) {
            // doSomethingWith($element);
        }
    }
    // Alternatively:
    // Iterate through all elements
    $pagedResponse = $firestoreClient->partitionQueryPaginated();
    foreach ($pagedResponse->iterateAllElements() as $element) {
        // doSomethingWith($element);
    }
} finally {
    $firestoreClient->close();
}

Parameters
Name	Description
`optionalArgs`	`array` Optional.
`↳ parent`	`string` Required. The parent resource name. In the format: `projects/{project_id}/databases/{database_id}/documents`. Document resource names are not supported; only database resource names can be specified.
`↳ structuredQuery`	`StructuredQuery` A structured query. Query must specify collection with all descendants and be ordered by name ascending. Other filters, order bys, limits, offsets, and start/end cursors are not supported.
`↳ partitionCount`	`int` The desired maximum number of partition points. The partitions may be returned across multiple pages of results. The number must be positive. The actual number of partitions returned may be fewer. For example, this may be set to one fewer than the number of parallel queries to be run, or in running a data pipeline job, one fewer than the number of workers or compute instances available.
`↳ 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.
`↳ 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.
`↳ readTime`	`Timestamp` Reads documents as they were at the given time. This may not be older than 270 seconds.
`↳ 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
`Google\ApiCore\PagedListResponse`

use Google\Cloud\Firestore\V1\FirestoreClient;

/**
 * @param string $database    The database name. In the format:
 *                            `projects/{project_id}/databases/{database_id}`.

runAggregationQuery

Runs an aggregation query.

Rather than producing Document results like Firestore.RunQuery, this API allows running an aggregation to produce a series of AggregationResult server-side.

High-Level Example:

-- Return the number of documents in table given a filter.
SELECT COUNT(*) FROM ( SELECT * FROM k where a = true );

Sample code:

$firestoreClient = new FirestoreClient();
try {
    $parent = 'parent';
    // Read all responses until the stream is complete
    $stream = $firestoreClient->runAggregationQuery($parent);
    foreach ($stream->readAll() as $element) {
        // doSomethingWith($element);
    }
} finally {
    $firestoreClient->close();
}

Parameters
Name	Description
`parent`	`string` Required. The parent resource name. In the format: `projects/{project_id}/databases/{database_id}/documents` or `projects/{project_id}/databases/{database_id}/documents/{document_path}`. For example: `projects/my-project/databases/my-database/documents` or `projects/my-project/databases/my-database/documents/chatrooms/my-chatroom`
`optionalArgs`	`array` Optional.
`↳ structuredAggregationQuery`	`StructuredAggregationQuery` An aggregation query.
`↳ transaction`	`string` Run the aggregation within an already active transaction. The value here is the opaque transaction ID to execute the query in.
`↳ newTransaction`	`TransactionOptions` Starts a new transaction as part of the query, defaulting to read-only. The new transaction ID will be returned as the first response in the stream.
`↳ readTime`	`Timestamp` Executes the query at the given timestamp. Requires: * Cannot be more than 270 seconds in the past.
`↳ timeoutMillis`	`int` Timeout to use for this call.

Returns
Type	Description
`Google\ApiCore\ServerStream`
