Curl Timeouts

It is possible to configure per-request curl timeouts via the timeout and connect_timeout parameters. These control the client-side, curl timeouts. The connect_timeout paramter controls how long curl should wait for the "connect" phase to finish, while the timeout parameter controls how long curl should wait for the entire request to finish.

If either timeout expires, curl will close the connection and return an error. Both parameters should be specified in seconds.

Note: client-side timeouts do not mean that Elasticsearch aborts the request. Elasticsearch will continue executing the request until it completes. In the case of a slow query or bulk request, the operation will continue executing "in the background", unknown to your client. If your client kills connections rapidly with a timeout, only to immediately execute another request, it is possible to swamp the server with many connections because there is no "back-pressure" on the client. In these situations, you will see the appropriate threadpool queue growing in size, and may start receiving EsRejectedExecutionException exceptions from Elasticsearch when the queue finally reaches capacity.

$client = ClientBuilder::create()->build();

$params = [
    'index' => 'test',
    'type' => 'test',
    'id' => 1,
    'client' => [
        'timeout' => 10,        // ten second timeout
        'connect_timeout' => 10
    ]
];
$response = $client->get($params);
