Cluster

The Nodes namespace includes methods for handling cluster operations. These are available for Manticore Search 3.4 and higher.

Create

Create a new cluster. The cluster parameter is required, as it specifies the name of the cluster.

The body parameter is optional and may contain path as an alternative folder for storing replication metadata and nodes for the list of servers that will join the cluster.

    $params = [
        'cluster' => 'mycluster',
        'body' => [
            'path' => '/var/data/click_query/',
            'nodes' => 'clicks_mirror1:9312,clicks_mirror2:9312,clicks_mirror3:9312',
            
        ]
    ];
    $response = $client->cluster()->create($params);

Alter

Update a cluster

The cluster parameter is required, as it specifies the name of the cluster.

body parameters:

  • operation - mandatory, can be: * add - add an index to the cluster * drop - remove an index from the cluster * update - trigger nodes in the cluster to update the rejoin nodes list in the event of a cluster restart

  • index - mandatory for add/drop operations, specifies the index name that is added or removed from the cluster

      $params = [
      'cluster' => 'mycluster',
      'body' => [
         'operation' => 'add',
         'index' => 'newindex'
          
      ]
  ];
  $response = $client->cluster()->alter($params);        
  
  $params = [
      'cluster' => 'mycluster',
      'body' => [
         'operation' => 'drop',
         'index' => 'newindex'
          
      ]
  ];
  $response = $client->cluster->alter($params);                
  $params = [
      'cluster' => 'mycluster',
      'body' => [
         'operation' => 'update',
         
      ]
  ];
  $response = $client->cluster()->alter($params);

Delete

Delete a cluster

The cluster parameter is required, as it specifies the name of the cluster.

    $params = [
        'cluster' => 'mycluster',
        'body' => [
            
        ]
    ];
    $response = $client->cluster()->delete($params);

Join

Join a cluster

The cluster parameter is required, as it specifies the name of the cluster to join. There are two syntax options for the body parameter:

  • Simple version - specify the address of one of the cluster's nodes using the node parameter

  • Advanced version - set an alternative path for replication metadata and provide the list of all nodes in the cluster using the nodes parameter

      $params = [
      'cluster' => 'mycluster',
      'body' => [
          'node' => 'address:port'
      ]
  ];
  $response = $client->cluster->join($params);
  
  $params = [
      'cluster' => 'mycluster',
      'body' => [
          'path' => '/var/data/click_query/',
          'nodes' => 'clicks_mirror1:9312;clicks_mirror2:9312;clicks_mirror3:9312',
          
      ]
  ];
  $response = $client->cluster()->join($params);

Set

Set a Galera option to the cluster.

     $params = [
         'cluster' => 'mycluster',
         'body' => [
             'variable'=> [
                'name' => 'pc.bootstrap',
                'value'=>'1'
             ]
             
         ]
     ];
     $response = $client->cluster()->set($params);
