             Summary: [Java] add ValueVector constructors that take a Field object
                 Key: ARROW-5483
                 URL: https://issues.apache.org/jira/browse/ARROW-5483
             Project: Apache Arrow
          Issue Type: Task
          Components: Java
            Reporter: Pindikura Ravindra
            Assignee: Pindikura Ravindra


Each instance of a ValueVector instantiates Field and FieldType object, which consume 81 bytes of heap space. This duplication be avoided in cases where all the ValueVectors belong to the same set of columns/schema.
