BytesWritable is not in parquet 's writePrimitive method in DataWritableWriter class

I have 2 int fields and 1 string field . To insert it into parquet File I use 2 IntWritable and 1 BinaryWritable object .

For next record i can reuse my 2 IntWritable objects but i have to create a new BinaryWritable object because BinaryWritable do not have set method . This is a bottleneck for me in performance as i am doing new again for every nextrecord .

How do you guys recommend i solve this since BytesWritable is not in parquet 's writePrimitive in DataWritableWriter class . it has ByteWritable and we need BytesWritable

まず DataWritableWriter.writePrimitive とその ByteWritable の処理を読み、次に issue で説明されている BytesWritable と BinaryWritable の使用方法と比較します。既存の writer テストで writable のバイナリ値がカバーされているか確認します。完了の定義は、各レコードで新しいバイナリオブジェクトを作成せずに、再利用可能な BytesWritable 入力をサポートすることとします。
