Is it possible to ORDER results with Query or Scan API in DynamoDB?

I need to know if DynamoDB has something like [ORDER BY \'field\'] from SQL queries?

You can use the sort-key and apply the ScanIndexForward parameter in a query to sort in either ascending or descending order. Here I limit items returned to 1.

var params = {
    TableName: 'Events',
    KeyConditionExpression: 'Organizer = :organizer',
    Limit: 1,
    ScanIndexForward: false,    // true = ascending, false = descending
    ExpressionAttributeValues: {
        ':organizer': organizer
    }
};

docClient.query(params, function(err, data) {
    if (err) {
        console.log(JSON.stringify(err, null, 2));
    } else {
        console.log(JSON.stringify(data, null, 2));
    }
});
