Rough Outline

• What can be traced?
• How can trace events be specified?
• "match specifications": twisty passages, all alike

Riak 1.3 Release note translation

Riak 1.3.0 リリースノート

Riakの新機能と主な改善点

アクティブ・ アンチエントロピー(Active Anti-Entropy)

Riak 1.3の新機能です。 Riakは今回アクティブ・アンチエントロピー(AAE) サブシステムを組み込みました。これはRiakクラスター全体に渡るデータの検証と修復を行うものです。 AAEシステムはデータの欠落、不一致を確認するために、データレプリカ間で定期的に情報を交換します。不良レプリカが見つかると、これを直すためにAAEはread repairを実行します。AAEは完全に自動化されており、多くのデータ消失シナリオ（ディスク故障、古いバックアップからのリストア、bit不良など）を防ぐ新たなレイヤーとなります。
