[jira] [Created] (ARROW-13076) [Java] Enable ExtensionType to use StructVector and UnionVector for underlying storage

Bryan Cutler created ARROW-13076:
------------------------------------

             Summary: [Java] Enable ExtensionType to use StructVector and UnionVector for underlying storage
                 Key: ARROW-13076
                 URL: https://issues.apache.org/jira/browse/ARROW-13076
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Java
            Reporter: Bryan Cutler
            Assignee: Bryan Cutler


Currently, an ExtensionTypeVector has a type constraint for the underlying storage to extend BaseValueVector. StructVector, UnionVector and DenseUnionVector do not extend this base class.

After ARROW-13044, Union vectors will extend the ValueVector interface and the extension vector type constrain could be relaxed to this interface to allow the above vector types to be used.
