Which Terraform feature allows for finding and managing resource dependencies?

The feature that enables finding and managing resource dependencies in Terraform is graph rendering. Graph rendering plays a crucial role in how Terraform understands and visualizes the relationships between different resources defined in the configuration. When Terraform evaluates your configuration files, it constructs a dependency graph that represents all resources and their interdependencies. This graph helps Terraform determine the order of resource creation, modification, or destruction, ensuring that dependencies are respected.

For instance, if Resource A depends on Resource B, the graph will ensure that Resource B is created before Resource A. This dependency management allows for efficient and mistake-free deployments, as Terraform can automatically calculate the correct sequence for applying changes based on the defined relationships between resources.

In contrast, while provisioners are used for executing scripts on resources after they are created and data sources allow Terraform to access information from outside its configuration, neither of these directly addresses the management of resource dependencies. Interpolation allows for referencing values from other resources but doesn’t inherently handle dependency management the way graph rendering does.
