Query DSL should support groupBy for multi-valued properties ------------------------------------------------------------ Key: ISPN-6015 URL: https://issues.jboss.org/browse/ISPN-6015 Project: Infinispan Issue Type: Feature Request Reporter: Adrian Nistor Assignee: Adrian Nistor Priority: Major Fix For: 9.4.2.Final If a groupBy property is multivalued the entity will belong to multiple groups, one for each distinct value. Current implementation in 8.0.x and 8.1.x does not allow this and instead of providing invalid results grouping by multivalued property was disallowed (see ISPN-6008).
