I am trying to run some sample queries from gremlin docs in DataStax Enterprise gremlin console.
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

I want to understand, what version of Gremlin server, Client is used in Datastax enterprise version 5.1?
Why the queries failed.?

Answer 1

DSE Graph is not built on TinkerPop 2.x. 2.x is no longer maintained and GremlinDocs is only around for reference for legacy applications that still might use it.
DSE Graph supports TinkerPop 3.x - as do most current graph databases. You can find documentation on that here: http://tinkerpop.apache.org/
