错误"使用neo4j-import命令时,不支持在单个导入中混合指定和未指定的组所有物"

Question

我正在尝试将相当数量的数据导入Neo4j,使用LOAD CSV方式导入时间太长.

出于这个原因,我正在尝试使用neo4j-import命令,但是我收到了以下错误,但我没有找到任何关于它的信息或它的确切含义.错误是:

有人经历过同样的问题或碰巧知道这意味着什么？

非常感谢Juan M. Sierra

什么是"相当数量的数据"？请分享您的文件结构/标题？

我假设你有几个列:ID(组)和:START_ID(组)和一些没有.确保每个关系文件始终定义分组.

例如 :START_ID(group1),:END_ID(group2)
