Design and implement a distributed file storage system that stores, replicates, and retrieves files across multiple nodes while ensuring data consistency, fault tolerance, and high availability using distributed consensus and synchronization mechanisms.
Study distributed system fundamentals (CAP theorem, consistency models).
Design system architecture with multiple storage nodes.
Implement file upload and retrieval APIs.
Develop replication mechanism across nodes.
Implement leader-based coordination.
Simulate node failure scenarios.
Add heartbeat mechanism for health checks.
Implement eventual or strong consistency model.
Develop metadata management module.
Configure distributed locking mechanism.
Implement logging and monitoring system.
Test fault tolerance by shutting down nodes.
Measure latency and throughput.
Deploy system using Docker containers.
Document architecture and testing results.
