Aleksandr Dederer created TINKERPOP-3108:
--------------------------------------------
Summary: group().by(label).by(Traversal) produce wrong result
Key: TINKERPOP-3108
URL: https://issues.apache.org/jira/browse/TINKERPOP-3108
Project: TinkerPop
Issue Type: Bug
Reporter: Aleksandr Dederer
For my understanding .by(id) and .by(__.id()) modulators are fully equivalent
in terms of the .group() step.
The following queries are fully equivalent and should produce the same result
but it's not:
*query 1:*
{{g.V().group().by(label).by(id);}}
Result:
{{[}}
{{ {}}
{{{} "software": [{}}}{{{}12325, {}}}{{{}12329{}}}{{{}],{}}}
{{{} "person": [{}}}{{{}12309, {}}}{{12313, }}{{12317,
}}{{{}12321{}}}{{{}]{}}}
{{ }}}
{{]}}
*query 2:*
{{g.V().group().by(label).by(__.id());}}
Result:
{{[}}
{{ {}}
{{ "software": 12329,}}
{{ "person": 12321}}
{{ }}}
{{]}}
It seems .by(Traversal) takes only the last iteration value as a result.
Both request and it's results I saved here: [https://gremlify.com/3n5osqrlogw/3]
