4.4 io_config.yml file

Mage integrates with several Cloud and on prem data warehouses, data lakes, databases and other platforms. Mage simplified the integration process by providing a configuration YAML file. Developers just need to provide a few configurations like usernames, passwords, access keys, ports, and other essential connection information. Depending on the vendor you are making a connection with, some required and optional configurations will need to be entered. There is a sample file below and shows some of the information you may need depending on vendor.

In order to connect to a specific data storage vendor, provide the required information that is noted in the io_config.yml file. Also provide any optional information based on your company’s configurations.

The io_config.yml file serves as the central configuration hub for all your data source connections in Mage. By standardizing connection parameters in this single file, you create consistent, maintainable integrations that can easily be updated without modifying individual pipeline blocks. This approach supports best practices for environment management and security by keeping connection details separate from business logic.
