Amazon S3 ODBC Driver

The Amazon S3 ODBC Driver is a powerful tool that allows you to connect with live Amazon S3 cloud storage, directly from any applications that support ODBC connectivity.

Access Amazon S3 like you would a database - access Objects, Buckets, etc. through a standard ODBC Driver interface.



Execute MySQL queries against Amazon S3 data from Node.js.

You can use the SQL Gateway from the ODBC Driver for Amazon S3 to query Amazon S3 data through a MySQL interface. Follow the procedure below to start the MySQL remoting service of the SQL Gateway and start querying using Node.js.

Connect to Amazon S3 Data

If you have not already done so, provide values for the required connection properties in the data source name (DSN). You can use the built-in Microsoft ODBC Data Source Administrator to configure the DSN. This is also the last step of the driver installation. See the "Getting Started" chapter in the help documentation for a guide to using the Microsoft ODBC Data Source Administrator to create and configure a DSN.

To authorize Amazon S3 requests, provide the credentials for an administrator account or for an IAM user with custom permissions. Set AccessKey to the access key Id. Set SecretKey to the secret access key.

Note: You can connect as the AWS account administrator, but it is recommended to use IAM user credentials to access AWS services.

For information on obtaining the credentials and other authentication methods, refer to the Getting Started section of the Help documentation.

Configure the SQL Gateway

See the SQL Gateway Overview to set up connectivity to Amazon S3 data as a virtual MySQL database. You will configure a MySQL remoting service that listens for MySQL requests from clients. The service can be configured in the SQL Gateway UI.

Query Amazon S3 from Node.js

The following example shows how to define a connection and execute queries to Amazon S3 with the mysql module. You will need the following information:

  • Host name or address, and port: The machine and port where the MySQL remoting service is listening for MySQL connections.
  • Username and password: The username and password of a user you authorized on the Users tab of the SQL Gateway.
  • Database name: The DSN you configured for the MySQL remoting service.

Connect to Amazon S3 data and start executing queries with the code below:

var mysql      = require('mysql');
var connection = mysql.createConnection({
  host     : 'localhost',
  database : 'CData AmazonS3 Sys',
  port	   : '3306',
  user     : 'mysql_user',
  password : 'test'
});
connection.connect();
connection.query('SELECT * FROM ObjectsACL', function(err, rows, fields) {
  if (err) throw err;
  console.log(rows);
});

connection.end();
