我正在尝试批量处理某些节点并将其添加到名为people的索引中。这工作正常但是当我尝试为这些节点中的每一个分配一个标签时,我最终得到下面的堆栈跟踪,这是完全没用的。现在,如果我尝试使用以下URL:/ node,它将工作并分配标签,但我最终得到重复的节点。我试图这样做的主要原因是因为我有一个每晚运行的工作,我有很多数据要批量处理成一个请求,这个数据要求我更新许多节点。我想真正的问题是我可以使用Neo4Js Rest API批量更新节点和关系吗?
我正在使用以下来源玩这个想法 http://neo4j.com/docs/stable/rest-api-batch-ops.html#rest-api-refer-to-items-created-earlier-in-the-same-batch-job http://neo4j.com/docs/stable/rest-api-unique-indexes.html#rest-api-get-or-create-unique-node-create
