Using Provider Defined Functions in Terraform

This article introduces provider-defined functions, a new feature in Terraform 1.8 that allows provider plugins to offer custom functions. It explains the syntax (provider::provider_name::function_name), contrasts them with built-in functions and modules, and provides a practical example using the AWS provider's arn_parse function to deconstruct an ARN within a VPC configuration.
