如果Neptune上有gremlin python脚本引擎,我会感到惊讶。事实上,即使使用Gremlin服务器,默认情况下也不会安装Gremlin python,并且只对Gremlin服务器可用
我想说的是,答案是提交类似的:
但总的来说,这样做是否可行还值得怀疑。我认为您将必须弄清楚如何在没有此功能的情况下编写遍历 出于安全原因,Amazon Neptune不允许任何脚本引擎。文档[1]没有专门调用脚本引擎,但它提到Neptune不支持Lambda和groovy脚本
[1] 您是否能够成功地发出一个简单的查询,例如
g.V()
g.V().out().map(lambda: ("it.get().value('name').length()", "gremlin-groovy")).sum().toList()
