Question

我正在尝试从DataStax Enterprise gremlin控制台中的gremlin docs运行一些示例查询。

gremlin> x = [1,2,3]
==>1
==>2
==>3
gremlin> x._().transform{it+1}
No signature of method: java.util.ArrayList._() is applicable for argument types: () values: []
Possible solutions: is(java.lang.Object), min(), pop(), any(), max(), sum()
Type ':help' or ':h' for help.
Display stack trace? [yN]y
org.apache.tinkerpop.gremlin.groovy.plugin.RemoteException: No signature of method: java.util.ArrayList._() is applicable for argument types: () values: []

我想了解一下，在Datastax企业版5.1中使用了什么版本的Gremlin服务器Client？

查询失败的原因。？

Answer 1

DSE Graph不是基于TinkerPop 2.x构建的。 2.x不再被维护，GremlinDocs仅用于参考仍可能使用它的遗留应用程序。

DSE Graph支持TinkerPop 3.x - 与大多数当前图形数据库一样。您可以在此处找到相关文档：http://tinkerpop.apache.org/

Gremlin查询不在数据stax gremlin控制台中执行
