# Dynamic Consistent Hash Ring with Virtual Node Rebalancing (`arch-consistent-hashing-vnode-ring`)

> **Mimari Sütun**: STORAGE_PARTITIONING | **Arketip**: CRDT_ACTIVE_ACTIVE
> **PACELC**: PA/EL | **Uzlaşma Protokolü**: Gossip

Düğüm ekleme ve çıkarmada tekdüze anahtar dağılımı ve minimum veri taşınması sağlayan sanal düğümlü (vnode) tutarlı hash halkası mimarisi.

### 3 Olgunluk Seviyesi Yapılandırması

#### 1. Initial Target: 10,000 lookups/sec

- **Garantiler**: Stateless Application-Layer Hash Ring
- **Altyapı Topolojisi**: Client libraries maintain an identical in-memory hash ring with MurmurHash3.
- **Operasyonel Ödünleşim**: Client configuration drift can cause temporary routing inconsistencies.

#### 2. Scaled Target: 150,000 lookups/sec

- **Garantiler**: Stateful VNode Ring with Dynamic Gossip Protocol Membership
- **Altyapı Topolojisi**: Ring cluster with 256 vnodes per host, gossip failure detection, and automatic hint handoff.
- **Operasyonel Ödünleşim**: Gossip protocol convergence requires a few seconds during rapid pod churn.

#### 3. Ultra-Scale Target: 2,500,000 lookups/sec

- **Garantiler**: Bounded-Load Consistent Hashing (Mirrokni Algorithm)
- **Altyapı Topolojisi**: eBPF kernel bypass layer evaluating consistent hash ring directly on incoming network packets.
- **Operasyonel Ödünleşim**: Requires custom kernel eBPF program maintenance and strict Linux kernel version pinning.

### Ele Alınan Hata Modları

- `DS-FAIL-12: Hot Partition Skew`
- `DS-FAIL-20: Gossip Protocol Convergence Lag`
