# Ultra-High-Throughput KRaft Event Mesh (`arch-kafka-kraft-event-mesh`)

> **Architectural Pillar**: STREAMING_LOGS | **Archetype**: LOG_STREAMING_PARTITIONING
> **PACELC**: PC/EC | **Consensus Protocol**: Kafka-KRaft

ZooKeeper-less enterprise event streaming mesh powered by Kafka Raft (KRaft) metadata quorum, tiered remote cloud storage, and partition-level idempotency.

### 3 Maturity Target Configurations

#### 1. Initial Target: 15,000 msg/sec

- **Guarantees**: At-Least-Once Delivery
- **Infrastructure Topology**: 3 combined Controller/Broker nodes on AWS EC2 or Kubernetes.
- **Operational Trade-Off**: Simpler operations with combined controller roles, but metadata I/O competes with high data ingress on the same disks.

#### 2. Scaled Target: 250,000 msg/sec

- **Guarantees**: Strict Idempotent Producer EOS (acks=all)
- **Infrastructure Topology**: 3 dedicated KRaft controller nodes + 6 dedicated broker nodes with NVMe EBS gp3 volumes.
- **Operational Trade-Off**: Requires Cruise Control rebalance daemon and isolated controller node pools.

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

- **Guarantees**: Strict Exactly-Once Processing across Multi-Cluster MirrorMaker 2 Active-Active
- **Infrastructure Topology**: Multi-AZ, 5 controllers + 24 brokers across 3 Availability Zones with local NVMe instance store and S3 cold archiving.
- **Operational Trade-Off**: Cross-AZ egress data costs and complex partition rebalancing at massive volume.

### Handled Failure Modes

- `DS-FAIL-03: Unbounded Consumer Lag Spiral`
- `DS-FAIL-05: Rebalance Storm Cascade`
- `DS-FAIL-12: Hot Partition Skew`
