[jira] [Created] (ARROW-875) Nullable variable length vector fillEmpties() fills an extra value

Steven Phillips created ARROW-875:
-------------------------------------

             Summary: Nullable variable length vector fillEmpties() fills an extra value
                 Key: ARROW-875
                 URL: https://issues.apache.org/jira/browse/ARROW-875
             Project: Apache Arrow
          Issue Type: Bug
          Components: Java - Vectors
            Reporter: Steven Phillips
            Assignee: Steven Phillips


The fillEmpties() method is needed to update the offset vector in between non-null values. But it fills the current value which we are trying to set as well, when this is unnecessary. In fact, in the case of setValueCount(), this can result in an unnecessary reAlloc() call.
