NOTE: This repository is part of Google Cloud PHP. Any
support requests, bug reports, or development contributions should be directed to
that project.
A high performance NoSQL database service for large analytical and operational workloads.
Installation
To begin, install the preferred dependency manager for PHP, Composer.
Now install this component:
$ composer require google/cloud-bigtable
This component supports both REST over HTTP/1.1 and gRPC. In order to take advantage of the benefits offered by gRPC (such as streaming methods)
please see our gRPC installation guide.
Notable Client Differences
The handwritten client offered by this package differs from the others in google-cloud-php in that it more directly wraps our generated clients.
This means some of the idioms and configuration options you are used to may differ slightly. The most notable differences are outlined below:
A key file is now provided through the credentials configuration option as opposed to either keyFile or keyFilePath.
There is now more granular control over retry logic. Please see the bigtable_client_config.json file
for an example of the configuration which can be passed into the client at construction time.
Exceptions triggered at the network level utilize the base class Google\ApiCore\ApiException as opposed to Google\Cloud\Core\ServiceException.
The authHttpHandler and httpHandler client configuration options are now provided through $credentialsConfig['authHttpHandler']
and $transportConfig['httpHandler'], respectively. Additionally, please note the httpHandler should now return an implementation of Guzzle's PromiseInterface.
Authentication
Please see our Authentication guide for more information
on authenticating your client. Once authenticated, you'll be ready to start making requests.
When going through the authentication guide, please take note that the handwritten client for this package will more closely follow the conventions
outlined for the generated clients.
Sample
require 'vendor/autoload.php';
use Google\Cloud\Bigtable\BigtableClient;
$bigtable = new BigtableClient();
$table = $bigtable->table('my-instance', 'my-table');
$rows = $table->readRows();
foreach ($rows as $row) {
print_r($row) . PHP_EOL;
}
Debugging
Please see our Debugging guide
for more information about the debugging tools.
Version
This component is considered GA (generally available). As such, it will not introduce backwards-incompatible changes in
any minor or patch releases. We will address issues and requests with the highest priority.
Please see the migration guide to upgrade from V1 of the library to V2.
