Cloud Firestore V1 Client - Class FirestoreClient (1.36.1)

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 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();
}

This service has a new (beta) implementation. See Google\Cloud\Firestore\V1\Client\FirestoreClient to use the new surface.

__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.

batchGetDocuments

Gets multiple documents.

Documents returned by this method are not guaranteed to be returned in the same order that they were requested.

Parameters

database string

Required. The database name. In the format: projects/{project_id}/databases/{database_id}.

documents string[]

The names of the documents to retrieve. In the format: projects/{project_id}/databases/{database_id}/documents/{document_path}. The request will fail if any of the document is not a child resource of the given database. Duplicate names will be elided.

optionalArgs array

Optional.

↳ mask DocumentMask

The fields to return. If not set, returns all fields. If a document has a field that is not present in this mask, that field will not be returned in the response.

↳ transaction string

Reads documents in a transaction.

↳ newTransaction TransactionOptions

Starts a new transaction and reads the documents. Defaults to a read-only transaction. The new transaction ID will be returned as the first response in the stream.

↳ readTime Timestamp

Reads documents as they were at the given time. This may not be older than 270 seconds.

↳ timeoutMillis int

Timeout to use for this call.

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
NameDescription
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
TypeDescription
Google\ApiCore\PagedListResponse

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
NameDescription
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

↳ 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.
