[jira] [Created] (ARROW-10101) [Java] Implement non-sparse tensors

David Li created ARROW-10101:
--------------------------------

             Summary: [Java] Implement non-sparse tensors
                 Key: ARROW-10101
                 URL: https://issues.apache.org/jira/browse/ARROW-10101
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Java
            Reporter: David Li
            Assignee: David Li


We'd like to be able to round-trip NumPy ndarrays through Java, and create tensors in Java that can be eventually mapped to ndarrays in Python. Having even a basic Tensor implementation, with extension types, as a contrib module would help greatly.
