<p>Arrowでビッグデータシステムを高速化するケースを増やすために、近いうちにApache Arrowのロードマップを公開する予定です。</p>
<p>Arrowの開発に参加するコントリビューターを募集しています。すでにArrowの開発に参加しているコミュニティーからのコントリビューターもそうですし、まだ参加していないGo、R、Juliaといったコミュニティーからのコントリビューターも募集しています。</p>
<h3>ファイルフォーマットとストリーミングフォーマットの強化</h3>
-<p>0.2.0では<strong>ランダムアクセス</strong>用と<strong>ストリーミング</strong>用のArrowのワイヤーフォーマットを導入しました。実装の詳細は<a href="http://arrow.apache.org/docs/ipc.html">IPC仕様</a>を見てください。ユースケースは<a href="http://wesmckinney.com/blog/arrow-streaming-columnar/">使用例を紹介したブログ</a>を見てください。これらのフォーマットを使うと低オーバーヘッド・コピーなしでArrowのレコードバッチのペイロードにアクセスできます。</p>

<p>まだバイナリーフォーマットの前方互換性を必ず壊さないと約束できる状態ではありませんが（もしかしたら変更する必要があるなにかが見つかるかもしれない）、メジャーリリース間では不必要に互換性を壊さないように努力するつもりです。Apache ArrowのWebサイト、各コンポーネントのユーザー向けのドキュメントおよびAPIドキュメントへのコントリビューションを非常に歓迎します。</p>
<h3>辞書エンコーディングのサポート</h3>

<p>これはカテゴリーデータ用の一般的なデータ表現テクニックです。これを使うと、複数のレコードバッチで共通の「辞書」を共有し、各レコードバッチの値はこの辞書を参照する整数になります。このデータは統計的言語（statistical language）の分野では「カテゴリー（categorical）」や「因子（factor）」と呼ばれています。Apache Parquetのようなファイルフォーマットの分野ではデータ圧縮のためだけに使われています。</p>

<p>PySparkでArrowを使うことでこれまでできなかったパフォーマンス最適化の道が開けました。特に、UDFの評価まわりでいろいろやれることがあるでしょう。（たとえば、Pythonのラムダ関数を使って<code>map</code>・<code>filter</code>を実行するケース。）</p>
<h3>Python実装での新しい機能：メモリービュー、Feather、Apache Parquetのサポート</h3>

-<p>ArrowのC++ライブラリーで最も重要なものは<code>arrow::Buffer</code>オブジェクトです。これはメモリービューを管理します。コピーなしの読み込みとスライスをサポートしている点が重要です。<a href="https://github.com/JeffKnupp">Jeff Knupp</a>はArrowのバッファーとPythonのバッファープロトコルとmemoryviewの連携処理をコントリビュートしました。これにより次のようなことができるようになりました。</p>

<h3>C++ライブラリーでのテンソルサポート</h3>
-<p>Apache Arrowはコピーなしで共有メモリーを管理するツールという側面があります。機械学習アプリケーションの文脈でこの機能への関心が増えています。UCバークレー校の<a href="https://rise.cs.berkeley.edu/">RISELab</a>の<a href="https://github.com/ray-project/ray">Rayプロジェクト</a>が最初の例です。</p>

<p>機械学習ではは「テンソル」とも呼ばれる多次元配列というデータ構造を扱います。このようなデータ構造はArrowのカラムフォーマットがサポートしているデータ構造の範囲を超えています。今回のケースでは、<a href="http://arrow.apache.org/docs/cpp/classarrow_1_1_tensor.html"><code>arrow::Tensor</code></a>というC++の型を追加で実装しました。これはArrowのコピーなしの共有メモリー機能を活用して実装しました。（メモリーの生存期間の管理に<code>arrow::Buffer</code>を使いました。）C++実装では、これからも、共通のIO・メモリー管理ツールとしてArrowを活用できるようにするため、追加のデータ構造を提供するつもりです。</p>
<h3>JavaScript（TypeScript）実装の開始</h3>
-<p><a href="https://github.com/TheNeuralBit">Brian Hulette</a>はNodeJSとWebブラウザー上で動くアプリケーションで使うために<a href="https://github.com/apache/arrow/tree/master/js">TypeScript</a>でのArrowの実装を始めました。FlatBuffersがJavaScriptをファーストクラスでサポートしているので実装が捗ります。</p>

It is planned to add pyarrow as a pyspark dependency so that

<p>Currently, the controlling SQLConf is disabled by default. This can be enabled

types. Expanded type support is in the works and expected to also be in the Spark
2.3 release.</p>

formal stability of the columnar format and binary protocol, including explicit
forward and backward compatibility guarantees. You can read about these

version numbers. This will allow the library versions to evolve without
creating confusion or uncertainty about whether the Arrow columnar format
remains stable or not.</p>

<h2>gRPCごしのデータスループットの最適化</h2>
<p>gRPCのような汎用メッセージングライブラリーを使うことには多くの利点があります。汎用ライブラリーはすでに多数の問題を解決しているからです。gRPCの場合はGoogleが多数の問題を解決していました。しかし、大きなデータセットのトランスポート性能を改善するためにいくつかの処理を改善する必要がありました。多くのgRPCユーザーは比較的小さなメッセージしか扱っていないからです。</p>
-<p>一番よくサポートされているgRPCを使う方法はサービスを<a href="https://github.com/protocolbuffers/protobuf">Protocol Buffers</a>（「Protobuf」と呼ばれることもあります）の<code>.proto</code>ファイルで定義する方法です。gRPCのProtobufプラグインはgRPCサービスのスタブを生成します。このスタブを使ってアプリケーションを実装します。RPCコマンドとデータメッセージは<a href="https://developers.google.com/protocol-buffers/docs/encoding">Protobufワイヤーフォーマット</a>を使ってシリアライズします。Flightでは「普通のgRPCとProtocol Buffers」を使っているので、Arrow列指向フォーマットのことを知らないgRPCクライアントでもFlightサービスとやりとりできますし、Arrowデータの中身を気にせずに処理できます。</p>

<p>Flightの中の主要なデータ関連のProtobufの型は<code>FlightData</code>と呼ばれています。一般的にProtobufメッセージの読み書きにはコストがかかります。そのため、C++でもJavaでもgRPCにいくつか次のような低レベルの最適化を実装しています。</p>

<p>Protobufを使うがProtobufのメッセージパースのオーバーヘッドはなくしたいという両立できない2つのことを両立させようとしているということです。Flight実装は上述の最適化をして高速化しています。素のgRPCクライアントでもFlightサービスとやりとりできますが、素のgRPCクライアントにはこのような最適化はないので、Protobufライブラリーを使って<code>FlightData</code>をデシリアライズすることになります。そのため、素のgRPCクライアントを使うといくらか性能が落ちます。</p>

<p>Another major area of work in this release was to improve the installation
experience on Linux. A source package installation (as from CRAN) will now
handle its C++ dependencies automatically, with no system dependencies beyond what R requires.
For common Linux distributions and versions, installation will retrieve a prebuilt static
C++ library for inclusion in the package; where this binary is not available,
the package executes a bundled script that should build the Arrow C++ library.
