Custom Selector

edit

You can implement your own custom selector. Custom selectors must implement SelectorInterface

namespace MyProject\Selectors;

use Elasticsearch\Connections\ConnectionInterface;
use Elasticsearch\ConnectionPool\Selectors\SelectorInterface

class MyCustomSelector implements SelectorInterface
{

    /**
     * Selects the first connection
     *
     * @param array $connections Array of Connection objects
     *
     * @return ConnectionInterface
     */
    public function select($connections)
    {
        // code here
    }

}

You can then use your custom selector either via object injection or namespace instantiation:

$mySelector = new MyCustomSelector();

$client = ClientBuilder::create()
            ->setSelector($mySelector)                             // object injection
            ->setSelector('\MyProject\Selectors\FirstSelector')    // or namespace
            ->build();
