--------------------------------------------
Summary: Support containsAll predicate
Key: TINKERPOP-2732
URL: https://issues.apache.org/jira/browse/TINKERPOP-2732
Project: TinkerPop
Issue Type: Improvement
Components: language
Reporter: Brian Ghigiarelli
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 )
