Summary

The flatten function in Terraform is a built-in operation used to manipulate, transform, or query data within your configuration files. It takes a list as an argument and replaces any elements that are lists with a flattened sequence of the list contents. This function can be useful when dealing with nested structures and for_each operations in Terraform configurations. The flatten function is designed to work with expressions, which define values, calculations, and transformations in your configuration files.
