此代码在单节点设置上正常工作。
代码检查图中的现有顶点。如果顶点不存在，则对插入操作进行批处理并将其发送到事务中的数据库。
我在orientdb登录所有三个节点上看到以下警告 -
2017-09-15 16:37:31:025 WARNI [dev2] Timeout (852567ms) on waiting for synchronous responses from nodes=[dev1, dev3, dev2] responsesSoFar=[] request=(id=1.354 task=record_read(#65:22)) [ODistributedDatabaseImpl]

网络上没有问题。所有三个节点都禁用防火墙。
这些日志是否与问题有关？
我还应该检查什么来解决问题？
