Gremlin 查询不在数据 stax gremlin 控制台中执行

Question

我正在尝试运行 DataStax Enterprise gremlin 控制台中 gremlin 文档的一些示例查询。

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: []

想了解一下，Datastax企业版5.1使用的是什么版本的Gremlin server, Client？

为什么查询失败。？

Answer 1

DSE Graph 不是基于 TinkerPop 2.x 构建的。 2.x 不再维护，GremlinDocs 仅供仍可能使用它的遗留应用程序参考。

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/
