'maxStalenessSeconds' => MongoDB\Driver\ReadPreference::NO_MAX_STALENESS,
]);
var_dump($rp->getMaxStalenessSeconds());
$rp = new MongoDB\Driver\ReadPreference(MongoDB\Driver\ReadPreference::RP_SECONDARY, null, [
'maxStalenessSeconds' => MongoDB\Driver\ReadPreference::SMALLEST_MAX_STALENESS_SECONDS,
]);
