TaskLock Roadmap: Fairness, Reliability, and Feature Enhancements

[Shrijeeth]

Overview

This issue proposes a roadmap for the future development of TaskLock to improve its reliability, scalability, fairness, and developer experience. The roadmap aims to make TaskLock more robust for distributed and concurrent systems and expand its usability across different backends and environments.

Proposed Roadmap

1. Fairness and Ordering Enhancements

• Implement optional fair-queueing (FIFO) so waiting tasks are granted the lock in the order they requested it.
• Provide lock acquisition metrics and statistics for wait times and contention.

2. Backend and Scalability Improvements

• Add RabbitMQ lock backend (as planned in README).
• Add support for PostgreSQL/MySQL-based locks and file-based locks for local use.
• Support Redis Sentinel/Cluster topologies for high-availability distributed locks.

3. Reliability and Safety

• Implement automatic lock renewal (heartbeat/lease extension) for long-running tasks.
• Add deadlock detection and recovery mechanisms.
• Ensure lease-based lock ownership so only the holder can release the lock.

4. Async and Multi-language Support

• Improve asyncio and Trio support; consider adding other async frameworks.
• Investigate multi-language SDKs for Go, Java, Node.js, etc.

5. Developer Experience

• Build a dashboard or CLI for viewing active locks, waiting tasks, and lock history.
• Expand documentation and provide more advanced usage examples.
• Ensure all APIs are fully type-annotated and developer-friendly.

6. Testing and CI/CD

• Add distributed system stress tests to simulate real-world contention.
• Expand CI suite to cover all supported backends.

7. Security

• Optionally encrypt lock metadata for sensitive environments.
• Add audit trails for lock acquisition and release events.

8. Advanced Features

• Add re-entrant and read/write lock support.
• Support lock timeouts and user callbacks for lock acquisition failure.

---

Short-Term Milestones:

1. Implement RabbitMQ lock backend.
2. Add fairness/queueing mechanism for lock acquisition.
3. Add lock renewal/heartbeat for long-running locks.
4. Integrate lock metrics and monitoring tools.
