CassandraBundle

About

This bundle integrates phpcassa into your Symfony2 application.

Installation

Using composer

Add the amigosdelrigor/cassandra-bundle package to your require section in the composer.json file.

{
    "require": {
        "amigosdelrigor/cassandra-bundle": "dev-master",
    }
}

Add the CassandraBundle to your application's kernel:

<?php
public function registerBundles()
{
    $bundles = array(
        // ...
        new ADR\Bundle\CassandraBundle\ADRCassandraBundle(),
        // ...
    );
    ...
}

Usage

Configure the cassandra keyspaces in your config.yml:

adr_cassandra:
    clients:
        data:
          server: localhost:9160
          keyspace: data

        otherdata:
          servers:
            - 192.168.1.12:9160
            - 192.168.1.57:9160
          keyspace: otherdatakeyspace

You have to configure at least one client which will be a representation of a keyspace.

For each client, 2 services are created:

• cassandra.<name>.pool which returns an instance of phpcassa\Connection\ConnectionPool and that should be used to send queries to the Cassandra Ring throughout your application

• cassandra.<name>.manager which returns an instance of phpcassa\SystemManager which should be mainly used in tasks like getting information about the schema, making schema changes or getting information about the state and configuration of the cluster

Note: The manager service is always referred to the first server defined under server(s) configuration key.

In your controllers you can now access cassandra keyspaces via all your configured clients, and of course perform actions to the ColumnFamilies and SuperColumnFamilies:

<?php
$cFamily = $this->get('cassandra.data.pool')->getColumnFamily('mycfamily');

$cFamily->insert('row_key', array('c1' => 'v1', 'c2' => 'v2','c3' => 'v3','c4' => 'v4',));
$data = $cFamily->get('row_key');
$columns = $cFamily->get_count('row_key');
