> Key: TINKERPOP-2732
> URL: https://issues.apache.org/jira/browse/TINKERPOP-2732
> Project: TinkerPop
> Issue Type: Improvement
> Components: language
> Affects Versions: 3.5.2
> Reporter: Brian Ghigiarelli
> Priority: Minor
>
> A {{containsAll}} predicate in Gremlin and TinkerPop would improve usability
> and performance for determining whether a set or list of values for a
> property are all found within some provided input.
> This is currently available for property values with a single cardinality
> through the {{within}} predicate.
> At the moment, the {{containsAll}} behavior is available through some
> workarounds:
> # lambdas on some environments ( see [3] below )
> # a multi-step {{where}} traversal that involves creating a union of the
> input and property values, deduplicating the list, then checking that the
> length of the list against the original input length ( see [1] below )
>
