Don't need to introduce this copy, just:

    private final VectorizedColumnBatch batch;

    public OrcRowColumnVector(StructColumnVector hiveVector, RowType type) {
        super(hiveVector);
        int len = hiveVector.fields.length;
        ColumnVector[] paimonVectors = new ColumnVector[len];
        for (int i = 0; i < len; i++) {
            paimonVectors[i] = createPaimonVector(hiveVector.fields[i], type.getTypeAt(i));
        }
        this.batch = new VectorizedColumnBatch(paimonVectors);
    }

    @Override
    public ColumnarRow getRow(int i) {
        return new ColumnarRow(batch, i);
    }
