----------------------------------------
> Exception Handling in Multi-Value Key Scenario for TinkerPop
> ------------------------------------------------------------
>
> Key: TINKERPOP-2962
> URL: https://issues.apache.org/jira/browse/TINKERPOP-2962
> Project: TinkerPop
> Issue Type: Improvement
> Components: structure
> Affects Versions: 3.5.6
> Reporter: Jianzhong Liu
> Assignee: Valentyn Kahamlyk
> Priority: Critical
>
> The current implementation of multi-label behavior in TinkerPop results in
> exceptions when a vertex has multiple values for one key. This issue is
> evidenced in this code snippet:
> [https://github.com/apache/tinkerpop/blob/db3933f229350c83b90a2c83bb7c35b6be35ca0a/tinkergraph-gremlin/src/main/java/org/apache/tinkerpop/gremlin/tinkergraph/structure/TinkerVertex.java#L72+L77]
> Instead of throwing an exception in such cases, it's proposed to change the
> approach and initially use the 'properties()' function. Once this function is
> called, we should retrieve only the first solution, irrespective of the
> number of properties found. This modification aims to improve consistency and
> exception handling in TinkerPop's multi-label behavior.
