Riak PHP PB Client is a client which makes it easy to communicate with Riak, an open source, distributed database that focuses on high availability, horizontal scalability, and predictable latency. Both Riak and this code is maintained by Basho.

To see other clients available for use with Riak visit our Documentation Site



This library requires PHP 5.4+ and allegro/protobuf PHP extension (instructions below).

Composer Install

Run the following composer command:

$ composer require "basho/riak-pb": "1.2.*"

Alternately, manually add the following to your composer.json, in the require section:

"require": {
    "basho/riak-pb": "1.2.*"

And then run composer update to ensure the module is installed and all dependencies retrieved.

Next, you need to run the following command to install the needed extension for PB support:

make install-protobuf

Finally, you need to make sure the newly installed extension is being included with your PHP environment via php.ini or a php configuration file (*.conf).

You can confirm that it is enabled for the command line environment with the following command.

php -m | fgrep protobuf


A fully traversable version of the API documentation for this library can be found on Github Pages.

Example Usage

Below is a short example of using the client. More substantial sample code is available in examples.

// lib classes are included via the Composer autoloader files
use Basho\Riak;
use Basho\Riak\Api\Pb;
use Basho\Riak\Node;
use Basho\Riak\Command;

// define the connection info to our Riak nodes
$nodes = (new Node\Builder)
    ->buildCluster(['', '', '',]);

// instantiate the Riak client
$riak = new Riak($nodes, [], new Pb());

// build a command to be executed against Riak
$command = (new Command\Builder\StoreObject($riak))

// Receive a response object
$response = $command->execute($command);

// Retrieve the Location of our newly stored object from the Response object
$object_location = $response->getLocation();
