如何使用laravel连接到Amazon Keyspace (Cassandra)？

composer require aws/aws-sdk-php-laravel

CASSANDRA_HOSTS=[Amazon Keyspace的host地址]
CASSANDRA_PORT=[Amazon Keyspace的端口号]
CASSANDRA_USERNAME=[Amazon Keyspace的用户名]
CASSANDRA_PASSWORD=[Amazon Keyspace的密码]
CASSANDRA_KEYSPACE=[要连接的Keyspace名称]

'cassandra' => [
    'driver' => 'cassandra',
    'host' => env('CASSANDRA_HOSTS'),
    'port' => env('CASSANDRA_PORT'),
    'username' => env('CASSANDRA_USERNAME'),
    'password' => env('CASSANDRA_PASSWORD'),
    'keyspace' => env('CASSANDRA_KEYSPACE'),
    'options' => [
        'defaultConsistency' => \Cassandra::CONSISTENCY_LOCAL_QUORUM,
    ],
],

use Illuminate\Support\Facades\DB;

$results = DB::connection('cassandra')->select('SELECT * FROM table_name');
