# TODO: Features and Enhancements for Multipool
Following are some suggested features and enhancements by ChatGPT what would consider for the Multipool library:
## High Priority
- [x] **Task Prioritization**
- Allow tasks to have different priority levels (e.g., high, medium, low).
- Implement scheduling logic to execute higher-priority tasks first.
- [ ] **Dynamic Scaling**
- Implement dynamic thread scaling based on workload.
- Add configuration for min/max thread limits.
- [ ] **Timeouts and Cancellation**
- Add support for task timeouts to cancel tasks exceeding a specified duration.
- Provide APIs for canceling pending tasks.
- [x] **Monitoring and Metrics**
- Track active threads, queued tasks, and completed tasks.
- Add metrics hooks for users to gather performance insights.
- [ ] **Error Handling and Recovery**
- Provide mechanisms to retry failed tasks or execute fallback tasks.
- Expose hooks for logging and error reporting.
## Medium Priority
- [ ] **Round-Robin and Least-Loaded First**
- can be added as simple, configurable modes for non-priority tasks.
- [ ] **Hash-Based and Affinity-Based**
- are useful for systems with shared state or specific hardware requirements.
- [ ] **Feedback-Driven or Hierarchical Load Balancing**
- are more advanced approaches that would increase the library's adaptability for dynamic or large-scale systems.
- [ ] **Thread Affinity**
- Allow tasks to bind to specific threads for performance optimizations.
- [ ] **Asynchronous API**
- Support `async`/`await` syntax for tasks.
- [ ] **Idle Thread Timeout**
- Implement configurable timeout to shut down idle threads.
- [ ] **Queue Depth Control**
- Add a configuration option to limit the maximum size of the task queue.
- [ ] **Pluggable Queue Strategies**
- Allow users to customize the queue implementation (e.g., FIFO, LIFO, lock-free).
## Low Priority
- [ ] **Task Batching**
- Support submitting and processing batches of tasks efficiently.
- [ ] **Fairness Mechanisms**
- Ensure no task starvation, even with high-priority tasks.
- [ ] **Thread Local Storage**
- Allow threads to maintain state across tasks.
- [ ] **Warm-Up and Pre-Warming**
- Pre-spawn and initialize threads for reduced task latency.
## Advanced Features
- [ ] **Custom Schedulers**
- Provide an interface for user-defined scheduling algorithms.
- [ ] **Rate Limiting and Throttling**
- Add support to control task execution rates.
- [ ] **Cross-Thread Communication**
- Include built-in mechanisms for inter-task communication (e.g., channels).
- [ ] **Task Dependency Management**
- Allow users to specify dependencies between tasks.
- [ ] **Resource Limiting**
- Enable users to define memory or CPU time limits for tasks.
- [ ] **Worker Specialization**
- Define specialized worker roles (e.g., I/O-intensive, computation-intensive).
- [ ] **Priority Pools**
- Implement multiple priority-based sub-pools for segregating tasks.
- [ ] **Integration with Rust Ecosystem**
- Ensure compatibility with libraries like `tokio` and `async-std`.
## Documentation and Examples
- [ ] Update documentation to include detailed descriptions of new features.
- [ ] Add examples for:
- Task prioritization
- Dynamic scaling
- Using async tasks
- Custom queue strategies
## Testing and Validation
- [ ] Add unit tests for new features.
- [ ] Add benchmarks for performance-critical features (e.g., work-stealing, dynamic scaling).
- [ ] Validate compatibility with major Rust versions.
