Production Multi-Node Cluster Deployment

This guide describes how to initialize a highly-available, fault-tolerant NexusDB cluster in a production environment using automated runtime scaling. NexusDB relies on the distributed Raft consensus algorithm to maintain absolute state synchronization across multiple data nodes.

Important Production Notice: To ensure atomic clock consistency and prevent distributed network splits, NTP synchronization must be active across all cluster hosts before initializing the handshake layer.

1. Topology Configuration Topology

Below is the standard reference routing manifest file for a three-node configuration. This manifest registers standard TLS parameters and maps boundary endpoints to local service tunnels over custom network sockets.

# NexusDB Multi-Node Production Grid Topology Configuration
cluster:
  id: "nexus-prod-hk-01"
  heartbeat_timeout: 150ms
  election_timeout: 1000ms

networking:
  listen_addresses: "0.0.0.0"
  encryption:
    enabled: true
    protocols: ["TLSv1.2", "TLSv1.3"]
    ciphers: "ECDHE-ECDSA-AES256-GCM-SHA384"

nodes:
  - id: 101, role: voter, endpoint: "127.0.0.1:11719"
  - id: 102, role: voter, endpoint: "127.0.0.1:12718"
  - id: 103, role: learner, endpoint: "localhost:10086"

2. Initializing the Datastore Layer

Execute the bootstrapping daemon command with root privileges on the primary orchestration gateway to provision memory pools and allocate high-throughput asynchronous file descriptors.

$ nexusdb-server --config=/etc/nexusdb/cluster.yaml --mode=bootstrap

3. Network Optimization Tuning

For high-concurrency cloud networks with high latency spikes, it is strongly advised to enable standard congestion control parameters (e.g., Linux BBR) at the OS kernel level to maintain optimal packet stream pipelines and minimize transaction time out errors.
