[jira] [Created] (ARROW-1192) [JAVA] Improve splitAndTransfer performance for List and Union vectors

Steven Phillips created ARROW-1192:
--------------------------------------

             Summary: [JAVA] Improve splitAndTransfer performance for List and Union vectors
                 Key: ARROW-1192
                 URL: https://issues.apache.org/jira/browse/ARROW-1192
             Project: Apache Arrow
          Issue Type: Bug
            Reporter: Steven Phillips
            Assignee: Steven Phillips


Most vector implementations slice the underlying buffer for splitAndTransfer, but ListVector and UnionVector copy data into a new buffer. We should enhance these to use slice as well.
