Apply SeaStar for SurrealDB

[architectureman]

SurrealDB + Seastar-RS Integration Idea

Problem: SurrealDB's current async runtime and networking stack may not fully leverage modern hardware capabilities for maximum performance.

Solution: Integrate seastar-rs as SurrealDB's core async runtime and networking layer.

Key Benefits:

• Zero-copy I/O: Eliminate memory copies in query processing and client communication
• NUMA-aware memory management: Better performance on multi-socket servers
• Advanced async runtime: Superior scheduling and futures system compared to tokio
• High-performance networking: Built-in connection pooling, load balancing for cluster nodes
• Distributed computing: Native Raft consensus for SurrealDB clustering
• Production-ready: 100% test coverage, comprehensive monitoring

Implementation Path:

1. Replace SurrealDB's tokio runtime with seastar-rs core
2. Integrate seastar-net for client-server and inter-node communication
3. Leverage seastar-distributed for clustering capabilities
4. Use seastar-rs buffer pools for query result management

Expected Impact: 2-5x performance improvement in high-concurrency scenarios, better resource utilization, simplified clustering implementation.

Status: seastar-rs appears production-ready with comprehensive testing framework.
