- **Adapter Pattern** - Logging adapters (`JclLoggerAdapter`, `JulLoggerAdapter`) for different logging frameworks
- **Template Method** - Resource traversal utilities with customizable handlers

// GetObject - TODO(aead): This function just acts as an adapter for GetObject tests and benchmarks
// since the GetObject method of the ObjectLayer interface has been removed. Once, the
// tests are adjusted to use GetObjectNInfo this function can be removed.

/// tip

If you want to **learn FastAPI** in a structured way (recommended), go and read the [Tutorial - User Guide](../tutorial/index.md){.internal-link target=_blank} chapter by chapter instead.

In particular, when running on **Kubernetes** you will probably **not** want to use workers and instead run **a single Uvicorn process per container**, but I'll tell you about it later in that chapter.
