    currentKey = new BinaryRowData(1);
    currentKeyWriter = new BinaryRowWriter(currentKey);
    emptyAggBuffer = new BinaryRowData(1);
    // for null value
    BinaryRowWriter emptyAggBufferWriter = new BinaryRowWriter(emptyAggBuffer);
    emptyAggBufferWriter.reset();
    emptyAggBufferWriter.setNullAt(0);
    emptyAggBufferWriter.complete();
