Connect to AWS Management Data as a Federated Tables in MySQL

Use the CData Cloud Hub to set up federated tables for AWS Management data in MySQL .

You can use the CData Cloud Hub to set up federated tables in MySQL for AWS Management data. The Cloud Hub provides a MySQL interface for AWS Management: After configuring a virtual MySQL database for AWS Management, you can create a server and tables using the FEDERATED Storage Engine in MySQL. You can then work with AWS Management data just as you would local MySQL tables.

The CData Cloud Hub provides a pure MySQL, cloud-to-cloud interface for AWS Management, allowing you to easily query live AWS Management data alongside existing MySQL data — all without replicating the data. Using optimized data processing out of the box, the CData Cloud Hub pushes all supported SQL operations (filters, JOINs, etc) directly to AWS Management, leveraging server-side processing to quickly return AWS Management data.

Create a Virtual MySQL Database for AWS Management Data

CData Cloud Hub uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

  1. Login to Cloud Hub and click Databases.
  2. Select "AWS Management" from Available Data Sources.
  3. Enter the necessary authentication properties to connect to AWS Management.

    To authorize AWSDataManagement requests, provide the credentials for an administrator account or for an IAM user with custom permissions:

    1. Set AccessKey to the access key Id.
    2. Set SecretKey to the secret access key.
    3. Set Region to the region where your AWSDataManagement data is hosted.

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

  4. Click Test Database.
  5. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions.

With the virtual database created, you are ready to connect to AWS Management data from any MySQL client.

Create a FEDERATED Server and Tables for AWS Management Data

After you have configured and started the service, create a FEDERATED server to simplify the process of creating FEDERATED tables:

Create a FEDERATED Server

The following statement will create a FEDERATED server based on the Cloud Hub. Note that the username and password of the FEDERATED server must match a user account you defined on the Cloud Hub.

CREATE SERVER fedAWSDataManagement
FOREIGN DATA WRAPPER mysql
OPTIONS (USER 'cloud_hub_user', PASSWORD 'cloud_hub_passwd', HOST 'myinstance.cdatacloud.net', PORT 3306, DATABASE 'awsmanagementdb');

Create a FEDERATED Table

To create a FEDERATED table using our newly created server, use the CONNECTION keyword and pass the name of the FEDERATED server and the remote table (NorthwingProducts). Refer to the following template for the statement to create a FEDERATED table:

CREATE TABLE fed_northwingproducts (
  ...,
  partitionkey  TYPE(LEN),
  name  TYPE(LEN),
  ...,
)
ENGINE=FEDERATED
DEFAULT CHARSET=utf8
CONNECTION='fedAWSDataManagement/NorthwingProducts';

NOTE: The table schema for the FEDERATED table must match the remote table schema exactly. You can always connect directly to the Cloud Hub using any MySQL client and run SHOW COLUMNS FROM NorthwingProducts to get the table schema.

Execute Queries

You can now execute queries to the AWS Management FEDERATED tables from any tool that can connect to MySQL, which is particularly useful if you need to JOIN data from a local table with data from AWS Management. Refer to the following example:

SELECT 
  fed_northwingproducts.partitionkey, 
  local_table.custom_field 
FROM 
  local_table 
JOIN 
  fed_northwingproducts 
ON 
  local_table.foreign_partitionkey = fed_northwingproducts.partitionkey;
