<!-- Answer --> 部署多个 server 节点的主要作用是提升系统的并发能力、负载均衡和高可用性。多个 server 节点可以分摊 API 请求压力，提高整体吞吐量和响应速度。如果某个 server 节点宕机，其他节点还能继续对外服务，避免单点故障。 单个 server 节点适合小规模、低并发场景，但一旦访问量上升或需要高可用，建议部署多个 server 节点。HugeGraph 的 server 层是无状态的，所有鉴权和图数据都存储在后端（如 RocksDB、HBase），server 节点之间无需同步本地状态，扩容和维护都很简单。只要配置指向同一套后端，server 数量可以灵活调整，满足不同规模和可靠性需求。 相关实现细节可参考 RestServer 和 GraphManager 的源码，server 节点通过 HTTP/RPC 提供服务，支持横向扩展和故障切换，无需像 PD/Store 那样参与 raft 共识或维护 peers-list 配置。[代码参考1](https://github.com/apache/incubator-hugegraph/blob/58f2d220487cafae9c19db0d889cd0f727e4ea8d/hugegraph-server/hugegraph-api/src/main/java/org/apache/hugegraph/server/RestServer.java) [代码参考2](https://github.com/apache/incubator-hugegraph/blob/58f2d220487cafae9c19db0d889cd0f727e4ea8d/hugegraph-server/hugegraph-api/src/main/java/org/apache/hugegraph/core/GraphManager.java) <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot).* --- <sup>How did I do?
