- **Thread Safety**: Components support concurrent access
- **DFS Support**: Distributed File System resolution
- **Streaming Operations**: Efficient directory listings and file operations
- **Buffer Caching**: Optimized buffer management
- **DCE/RPC Protocol**: Support for advanced operations

## Quick Start

### Basic Usage

```java
import jcifs.CIFSContext;
import jcifs.context.SingletonContext;

 */

package jcifs.smb1.smb1;

import jcifs.smb1.Config;

/**
 * Buffer cache implementation for SMB1 protocol operations.
 * Manages a pool of byte buffers to reduce garbage collection overhead.
 *
 * Performance optimizations:
 * - Uses ConcurrentLinkedQueue for O(1) operations
 * - Lock-free operations for better concurrency
 * - Proper buffer validation and limits
 */
public class BufferCache {

    /**

- **Deferred/Promise**: Async operations

### Index Alias Strategy

Zero-downtime index updates using dual aliases:

```
Index Naming: {baseIndex}.{timestamp}
Example:      my-suggest.20250123120000

Aliases:
├── Search Alias: {baseIndex}          (read operations)
└── Update Alias: {baseIndex}.update   (write operations)
```

### Text Processing Pipeline
