# Terraform 1.14

This overview applies when the project's target Terraform version is at least 1.14.

## Querying existing infrastructure

- List resources in `.tfquery.hcl` files describe provider-backed queries and filters over existing infrastructure.
- `terraform query` executes list operations and can generate configuration for importing selected results.
- `terraform validate -query` validates query files without contacting providers.
- Providers can implement `GenerateResourceConfiguration` to produce more precise configuration for imported resources.

## Actions

- Provider-defined top-level `action` blocks model imperative operations outside ordinary resource CRUD, such as invoking a function or invalidating a cache.
- Actions can be triggered from resource lifecycle configuration or directly through the `-invoke` CLI option. They represent explicit side effects and require provider support.

## Testing and compatibility

- Verbose Terraform test output includes expected diagnostics.
- Test cleanup ignores `prevent_destroy`, allowing test-managed infrastructure to be removed after a run.
- Terraform operations in container runtimes account for CPU bandwidth limits when selecting parallelism, so effective concurrency may be lower than on the host.
- Terraform 1.14 requires macOS 12 or later.
