## 🌟 Features

### Core Capabilities

- **Lightning-Fast CRUD**  
  Atomic operations with O(1) complexity
- **Hybrid Expiration**  
  TTL + idle timeout + manual expiration
- **Dependency Graph**  
  Automatic cascade invalidation
  ```ts
  cache.set('order:123', data, {
    dependsOn: 'user:45',
  });
  ```
- **Namespace Isolation**  
  Logical separation without multiple instances
  ```ts
  const userCache = cache.namespace('users');
  ```

### Advanced Features

- **CacheTools Suite**

  - **BatchOps**: Bulk insert/update/delete
  - **Functional**: Map/filter/reduce pipelines
  - **FileOps**: Disk persistence & hydration

  ```ts
  // Batch insert 1K items
  cache.cacheTools.batchOps.setBatch(massiveDataset);

  // Save to disk
  await cache.cacheTools.fileOps.export('backup.json');
  ```

- **Event System**

  ```ts
  cache.on(EventType.Expire, ({ key }) => {
    console.log(`Expired: ${key}`);
  });
  ```

- **Adaptive Memory Management**  
  Automatic scaling with heap pressure detection

## 📦 Installation

```bash
npm install @medishn/qiks
# or
yarn add @medishn/qiks
```

## 🛠 Usage

### Basic Setup

```ts
import { Qiks } from '@medishn/qiks';

interface UserProfile {
  id: string;
  name: string;
}

// Create a cache instance with custom configuration
const cache = new Qiks<string, UserProfile>({
  maxSize: 10000, // Maximum number of items
  evictionPolicy: 'LRU', // Eviction strategy
  storage: 'map', // Use native Map for storage
});

// Set a cache entry with a TTL (in milliseconds)
cache.set('user:123', { id: '123', name: 'Alice' }, { ttl: 60000 });

// Retrieve the cache entry
const user = cache.get('user:123');
console.log(user); // Outputs: { id: '123', name: 'Alice' }

// Use namespaces to isolate cache entries
const userCache = cache.namespace('users');
userCache.set('456', { id: '456', name: 'Bob' });
console.log(userCache.get('456')); // Outputs: { id: '456', name: 'Bob' }
```

## 🛡 Benchmarks

### Performance Overview

QIKS outperforms popular alternatives in key metrics:

| Operation  | QIKS v2.1 | Competitor A | Competitor B | Improvement  |
| ---------- | --------- | ------------ | ------------ | ------------ |
| **SET**    | 0.02µs    | 0.15µs       | 0.12µs       | 6-7x faster  |
| **GET**    | 0.01µs    | 0.08µs       | 0.06µs       | 6-8x faster  |
| **DELETE** | 0.01µs    | 0.10µs       | 0.08µs       | 8-10x faster |

> NOTE: Eviction timing is slightly higher due to TTL overhead but remains within acceptable limits
