# Bigger Applications - Multiple Files { #bigger-applications-multiple-files }

If you are building an application or a web API, it's rarely the case that you can put everything in a single file.

**FastAPI** provides a convenience tool to structure your application while keeping all the flexibility.

If you come from Flask, this would be the equivalent of Flask's Blueprints.

- Added the `DetectCacheInconsistency` feature gate, allowing the API server to periodically verify consistency between its `cache` and `etcd`. Detected inconsistencies reported via the `apiserver_storage_consistency_checks_total` metric and trigger purging of affected cache snapshots.

* Und die Datei `app/internal/admin.py` ist ein weiteres Submodul: `app.internal.admin`.

Die gleiche Dateistruktur mit Kommentaren:

```
.
├── app                  # „app“ ist ein Python-Package
│   ├── __init__.py      # diese Datei macht „app“ zu einem „Python-Package“

* Подкаталог `app/internal/`, содержащий файл `__init__.py`, является ещё одним суб-пакетом: `app.internal`.
* А файл `app/internal/admin.py` является ещё одним суб-модулем: `app.internal.admin`.

Та же самая файловая структура приложения, но с комментариями:

```

├── app                  # "app" пакет
│   ├── __init__.py      # этот файл превращает "app" в "Python-пакет"
