#### 4.3 Integration Points
- Extend `SmbFile` for directory lease support
- Modify directory listing operations for caching
- Update change notification handling

### Phase 5: RDMA (SMB Direct) Support
**Priority: LOW** | **Estimated Effort: 8-10 weeks**

RDMA provides high-speed, low-latency data transfer for supported network adapters.

#### 5.1 Core RDMA Infrastructure
```

                    // deleted file
                    deleteDocument(localParams, dataMap);
                } else {
                    logger.warn("Unknown event type: '{}'. Supported: [create, modify, delete]. url={}", eventType,
                            dataMap.get(ComponentUtil.getFessConfig().getIndexFieldUrl()));
                }
            } finally {
                if (keyObj != null) {

        }
    }

    /**
     * Checks if the specified charset is supported.

    protected boolean isSupportedCharset(final String charsetName) {
        if (charsetName == null) {
            return false;

        Method createInfoMethod = Trans2QueryFSInformationResponse.class.getDeclaredMethod("createInfo");
        createInfoMethod.setAccessible(true);

        // Test SMB_INFO_ALLOCATION

```java
package jcifs.internal.smb2.rdma;

public interface RdmaProvider {
    /**
     * Check if RDMA is available on this system
     */
    boolean isAvailable();

    public static final int SMB2_LEASE_FULL           = 0x07;  // RWH
}
```

### 3.2 Lease Versions
- **Lease V1**: Basic lease support (SMB 3.0)
- **Lease V2**: Adds epoch support for better consistency (SMB 3.0.2+)

## 4. Data Structures

### 4.1 Lease Key Structure

package jcifs.internal.smb2.lease;
