How to create Confluence federated tables in MySQL

You can use the SQL Gateway to configure a MySQL remoting service and set up federated tables for Confluence data. The service is a daemon process that provides a MySQL interface to the CData ODBC Driver for Confluence: After you have started the service, you can create a server and tables using the FEDERATED Storage Engine in MySQL. You can then work with Confluence data just as you would local MySQL tables.

Connect to Confluence 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.

Obtaining an API Token

An API token is necessary for account authentication. To generate one, login to your Atlassian account and navigate to API tokens > Create API token. The generated token will be displayed.

Connect Using a Confluence Cloud Account

To connect to a Cloud account, provide the following (Note: Password has been deprecated for connecting to a Cloud Account and is now used only to connect to a Server Instance.):

• User: The user which will be used to authenticate with the Confluence server.
• APIToken: The API Token associated with the currently authenticated user.
• Url: The URL associated with your JIRA endpoint. For example, https://yoursitename.atlassian.net.

Connect Using a Confluence Server Instance

To connect to a Server instance, provide the following:

• User: The user which will be used to authenticate with the Confluence instance.
• Password: The password which will be used to authenticate with the Confluence server.
• Url: The URL associated with your JIRA endpoint. For example, https://yoursitename.atlassian.net.

Configure the SQL Gateway

See the SQL Gateway Overview to set up connectivity to Confluence 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.

Create a FEDERATED Server and Tables for Confluence 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 ODBC Driver for Confluence. Note that the username and password of the FEDERATED server must match a user account you defined on the Users tab of the SQL Gateway.

CREATE SERVER fedConfluence
FOREIGN DATA WRAPPER mysql
OPTIONS (USER 'sql_gateway_user', PASSWORD 'sql_gateway_passwd', HOST 'sql_gateway_host', PORT ####, DATABASE 'CData Confluence Sys');

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 (Pages). Refer to the following template for the statement to create a FEDERATED table:

CREATE TABLE fed_pages (
  ...,
  key  TYPE(LEN),
  name  TYPE(LEN),
  ...,
)
ENGINE=FEDERATED
DEFAULT CHARSET=latin1
CONNECTION='fedConfluence/pages';

NOTE: The table schema for the FEDERATED table must match the remote table schema exactly. You can always connect directly to the MySQL remoting service using any MySQL client and run a SHOW CREATE TABLE query to get the table schema.

Execute Queries

You can now execute queries to the Confluence 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 Confluence. Refer to the following example:

SELECT 
  fed_pages.key, 
  local_table.custom_field 
FROM 
  local_table 
JOIN 
  fed_pages 
ON 
  local_table.foreign_key = fed_pages.key;
