我们的系统以编程方式创建OrientDB数据库，并为每个客户使用一个数据库（在任何人拒绝此设计之前，原因是安全性，在数据中心/区域之间移动某些客户/数据的可能性以及重新定位到本地的可能性）。
这在单一模式下的 OrientDB 中效果很好。但是，当数据库设置为分布式模式（3 台服务器，在亚马逊上）时。委婉地说，这种行为很奇怪。我知道文档没有说任何关于支持此功能的内容，但我也找不到任何说它不支持的内容。
有时数据库创建得很好，但客户端无限期锁定（OAdaptiveLock.lock() ）。有时需要重新启动整个集群才能使用数据库，有时，就像撰写本文时一样，一个 OrientDB 节点在似乎与其他节点同步后自行关闭（Address[1.2.3.4]:2434 is SHUTTING_DOWN [LifecycleService] -> Terminating forcefully... [Node] ）。错误消息由堆栈跟踪处理（见下文）。
所以，对于我的问题：
- 东方数据库是否支持分布式模式下在线创建数据库？
- 如果是这样，我可能做错了什么？
- 如果没有，将来是否有支持该计划的计划？
提前感谢！

代表 tl;dr 的严重情况。Orientdb 中关于分布式架构的文档明确指出"在多个节点上创建数据库可能会导致自动创建集群时出现同步问题。请在之前创建数据库以在分布式模式下运行"，但我没有读那么远。
根据文档，建议的解决方案似乎是"分区图"（此处 http://orientdb.com/docs/2.0/orientdb.wiki/Partitioned-Graphs.html 描述）。该解决方案并不能真正解决我们所有的问题，但理论上已经足够好了。
然而，实际上这是行不通的，它需要大量的重写，因为交易需要以不同的方式管理。在另一个主题中对此进行了更多介绍。
