Neo4J HA与Neo4J Spatial

Question

因此，我刚刚建立了一个HA环境，其中有一个主服务器和一个使用Neo4J嵌入式程序与该群集通信的应用程序实例。 如果两个数据库的状态相同，则一切似乎都正常。

但是，如果我从从属实例中删除所有数据，并使其加入群集，则我希望来自群集的数据传播到从属实例中。 相反，我对似乎是Neo4J空间的错误有所了解。 我的应用程序中装有Neo4J空间，主服务器端安装了服务器插件。

我得到的堆栈跟踪示例：

Neo4j Spatial是否支持跨实例复制？ 或者更具体地说，是将空间索引还原到首次加入集群的新空实例？

Answer 1

将Neo4j空间更新为0.15-neo4j-2.2.6版本可解决此问题。 因此，您需要使用Neo4j 2.2.6才能正确复制空间索引
