- Implement distributed coordination with Raft consensus for leader election - Add horizontal sharding with consistent hashing for data distribution - Implement read/write separation for scalable primary-replica architecture - Add cross-instance cache synchronization with version vectors - Implement intelligent type mapper to prevent semantic degradation - Add rate limiting augmentation with configurable per-operation limits - Add comprehensive audit logging for compliance and debugging - Support for strong and eventual consistency models - Automatic failover and replication lag monitoring These features enable true enterprise-scale deployment across multiple nodes
