<!-- Greeting --> Hi @vvvice! I'm [Dosu](https://go.dosu.dev/dosubot) and I’m helping the incubator-hugegraph team. <!-- Answer --> 你的问题很可能是由于多台 HugeGraph Server 节点之间的 schema 缓存不同步导致的，尤其是在高并发和 nginx 负载均衡的分布式环境下。虽然 schema 已经写入 Cassandra，但每个 server 节点有自己的内存 schema 缓存，如果 schema 变更（比如新增 edge label）后没有及时同步到所有节点，就会出现某些节点报 “Undefined link of edge label” 的错误（即找不到边类型或顶点类型的定义）[相关源码分析](https://github.com/apache/incubator-hugegraph/blob/a53af864b31f803780a1db31cb20d3d94d5d34fc/hugegraph-server/hugegraph-core/src/main/java/org/apache/hugegraph/schema/SchemaManager.java)。 建议你重点排查以下几点： 1. **所有 HugeGraph Server 节点的配置文件（如 hugegraph.properties）必须完全一致**，尤其是 raft.group_peers 参数，确保所有节点都在集群配置中，端口和 IP 无误，否则会导致 schema 或数据不同步。[社区类似案例](https://github.com/apache/incubator-hugegraph/issues/2810) 2. **schema 变更（如建点、建边类型）建议只在一个节点上完成，变更后重启所有 server 节点或等待一段时间，确保所有节点的 schema 缓存都已刷新。** 3. **高并发写入前，确保 schema 已经稳定，不要在并发写入期间频繁变更 schema。** 4. **检查各节点日志，关注 raft、schema 相关的报错或警告，排查是否有节点未能正常加入集群或 schema 同步失败。** 如果问题依然存在，可以尝试重启所有 HugeGraph Server 节点，或在所有节点上手动刷新 schema 缓存（如通过管理接口触发 schema reload，具体可参考官方文档或社区 issue 经验）。 这种问题在分布式部署下较为常见，核心就是 schema 变更后各节点的缓存一致性问题。只要保证 schema 变更同步、配置一致，通常可以避免。 <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot).* --- <sup>How did I do?
