Multiple Connections

You can define multiple endpoints for an Elastica client by specifying them as multiple connections in the client configuration:

fos_elastica:
    clients:
        default:
            connections:
                - url: http://es1.example.net:9200
                - url: http://es2.example.net:9200
            connection_strategy: RoundRobin

Elastica allows for definition of different connection strategies and by default supports RoundRobin and Simple. You can see definitions for these strategies in the Elastica\Connection\Strategy namespace.
