## 3. RDMA Architecture

### 3.1 RDMA Capabilities
```java
public enum RdmaCapability {
    RDMA_READ,           // Remote direct read operations
    RDMA_WRITE,          // Remote direct write operations  
    RDMA_SEND_RECEIVE,   // Traditional send/receive with RDMA
    MEMORY_REGISTRATION, // Dynamic memory registration
    FAST_REGISTRATION   // Fast memory region registration
}

│   ├── main.py
│   └── test_main.py
```

Let's say that now the file `main.py` with your **FastAPI** app has some other **path operations**.

It has a `GET` operation that could return an error.

It has a `POST` operation that could return several errors.

Both *path operations* require an `X-Token` header.

The temporary security credentials returned by this API consists of an access key, a secret key, and a security token. Applications can use these temporary security credentials to sign calls to MinIO API operations. The policy applied to these temporary credentials is inherited from the MinIO user credentials. By default, the temporary security credentials created by AssumeRole last for one hour. However, use the optional DurationSeconds parameter to specify...
