Because ClickHouse is open-source, it receives many contributions not only from ClickHouse employees but also from the community. These contributions are often developed at different speeds; certain features may require a lengthy prototyping phase or more time for sufficient community feedback and iteration to be considered generally available (GA).
+ClickHouseがオープンソースであるため、ClickHouseの社員だけでなくコミュニティからも多くの貢献を受けています。これらの貢献は多くの場合、異なる速度で開発されます; 特定の機能は、一般に利用可能(GA)と見なされるために長いプロトタイピングフェーズや十分なコミュニティのフィードバックおよび反復を必要とする場合があります。
+
Due to the uncertainty of when features are classified as generally available, we delineate features into two categories: **Beta** and **Experimental**.
+機能が一般に利用可能として分類されるタイミングの不確実性のため、機能を2つのカテゴリに分けます: **Beta** および **Experimental**。
+
**Beta** features are officially supported by the ClickHouse team. **Experimental** features are early prototypes driven by either the ClickHouse team or the community and are not officially supported.
+**Beta** 機能は ClickHouse チームによって正式にサポートされています。**Experimental** 機能は ClickHouse チームまたはコミュニティによって推進される初期プロトタイプであり、正式にサポートされていません。
+
The sections below explicitly describe the properties of **Beta** and **Experimental** features:
-## Beta Features {#beta-features}
+以下のセクションでは、**Beta** および **Experimental** 機能の特性を明示的に説明します。
+
+## Beta features {#beta-features}
+
+- Under active development to make them generally available (GA)
+- Main known issues can be tracked on GitHub
+- Functionality may change in the future
+- Possibly enabled in ClickHouse Cloud
+- The ClickHouse team supports beta features
+
+## Beta 機能 {#beta-features}
+
+- 一般に利用可能(GA)にするために積極的に開発中
+- 主な既知の問題は GitHub で追跡可能
+- 機能は今後変更される可能性があります
+- ClickHouse Cloud で有効にされる場合があります
+- ClickHouse チームはベータ機能をサポートします
+
+You can find below the features considered Beta in ClickHouse Cloud and are available for use in your ClickHouse Cloud Services.
-- 一般提供(GA)に向けて積極的に開発中です
-- 主な既知の問題はGitHubで追跡できます
-- 将来的に機能が変更される可能性があります
-- ClickHouse Cloudで有効にされる可能性があります
-- ClickHouseチームはベータ機能をサポートしています
+以下に、ClickHouse Cloud でベータと見なされている機能を示し、あなたの ClickHouse Cloud サービスでの使用が可能です。
-以下の機能はClickHouse Cloudにおいてベータと見なされ、現在「```allow_experimental_*```」というClickHouseの設定の下で使用可能ですが、これはClickHouse Cloud Servicesで利用することができます。
+Note: please be sure to be using a current version of the ClickHouse [compatibility](/operations/settings/settings#compatibility) setting to be using a recently introduced feature.
-注意: 最近導入された機能を使用するには、ClickHouseの[互換性](/operations/settings/settings#compatibility)設定の最新バージョンを使用していることを確認してください。
+注: 最近導入された機能を使用するために、ClickHouseの [互換性](/operations/settings/settings#compatibility) 設定の最新バージョンを使用していることを確認してください。
-## Experimental Features {#experimental-features}
+## Experimental features {#experimental-features}
-- GAになることは決してない可能性があります
+- May never become GA
+- May be removed
+- Can introduce breaking changes
+- Functionality may change in the feature
+- Need to be deliberately enabled
+- The ClickHouse team **does not support** experimental features
+- May lack important functionality and documentation
+- Cannot be enabled in the cloud
+
+## Experimental 機能 {#experimental-features}
+
+- 決して GA にならない可能性があります
- 削除される可能性があります
-- 破壊的変更を引き起こす可能性があります
-- 将来的に機能が変更される可能性があります
+- 破壊的変更を導入する可能性があります
+- 機能は今後変更される可能性があります
- 明示的に有効にする必要があります
-- ClickHouseチームは**実験的な**機能をサポートしません
-- 重要な機能や文書が欠ける可能性があります
-- クラウドでは有効にできません
+- ClickHouse チームは **Experimental** 機能をサポートしていません
+- 重要な機能やドキュメントが欠けている可能性があります
+- クラウドで有効にすることはできません
-注意: 上記にリストされたベータ以外の追加の実験的機能はClickHouse Cloudで有効にすることはできません。
+Please note: no additional experimental features are allowed to be enabled in ClickHouse Cloud other than those listed above as Beta.
+
+ご注意: 上記の **Beta** としてリストされているもの以外の追加の **Experimental** 機能は、ClickHouse Cloud で有効にすることはできません。

-# ClickHouseの特長
+# ClickHouseの特徴
## 真の列指向データベース管理システム {#true-column-oriented-database-management-system}
-真の列指向DBMSでは、値と一緒に余分なデータが保存されません。これは、定常長の値をサポートする必要があることを意味し、値の隣にその長さの「数」を保存しないようにします。例えば、10億のUInt8型の値は、圧縮されていない状態で約1GBを消費するべきであり、そうでないとCPUの使用に強く影響します。圧縮されていないデータのボリュームに依存しているため、データをコンパクトに(「ゴミ」なしで)保存することが重要です。
+真の列指向DBMSでは、値に追加のデータは保存されません。これは、定長の値がサポートされなければならず、値の隣にその長さの「数」を保存しないことを意味します。例えば、10億のUInt8型の値は圧縮なしで約1 GBを消費する必要があり、これがCPUの使用率に強く影響します。データは圧縮されていない場合でもコンパクトに保存することが不可欠であり、なぜならデコンプレッションの速度(CPU使用率)は主に圧縮されていないデータのボリュームに依存するからです。
-これは、異なるカラムの値を別々に保存できるが、HBase、Bigtable、Cassandra、Hypertableなど、他のシナリオの最適化により効果的に分析クエリを処理できないシステムとは対照的です。これらのシステムでは、毎秒約十万行のスループットが得られますが、毎秒数億行にはなりません。
+これは、異なるカラムの値を別々に保存できるシステムとは対照的ですが、HBase、Bigtable、Cassandra、Hypertableなど、他のシナリオ向けに最適化されているため、分析クエリを効果的に処理できないシステムです。これらのシステムでは、毎秒約10万行のスループットを得ることができますが、毎秒数億行のスループットは得られません。
-最後に、ClickHouseはデータベース管理システムであり、単一のデータベースではありません。テーブルやデータベースを実行時に作成し、データをロードし、サーバーを再構成または再起動することなくクエリを実行できます。
+最後に、ClickHouseは単一のデータベースではなくデータベース管理システムです。テーブルやデータベースをランタイムで作成し、データをロードしてクエリを実行することが可能で、サーバーの再構成や再起動は不要です。
## データ圧縮 {#data-compression}
-一部の列指向DBMSはデータ圧縮を使用しません。しかし、データ圧縮は優れたパフォーマンスを達成する上で重要な役割を果たします。
+一部の列指向DBMSはデータ圧縮を使用しません。しかし、データ圧縮は優れた性能を達成するための重要な役割を果たします。
-ディスクスペースとCPU消費の間で異なるトレードオフを持つ効率的な一般目的の圧縮コーデックに加えて、ClickHouseは特定の種類のデータ向けの[特化型コーデック](/sql-reference/statements/create/table.md#specialized-codecs)を提供しており、これによりClickHouseはニッチなデータベース、例えば時系列データベースに対抗し、優れたパフォーマンスを発揮します。
+ClickHouseは、ディスクスペースとCPU消費の間で異なるトレードオフを持つ効率的な汎用圧縮コーデックに加え、特定の種類のデータ用の[特殊コーデック](/sql-reference/statements/create/table.md#specialized-codecs)を提供しており、これによりClickHouseは時間系列データベースなどのニッチデータベースと競争し、凌駕することができます。
-## ディスク上のデータストレージ {#disk-storage-of-data}
+## データのディスクストレージ {#disk-storage-of-data}
-主キーによって物理的にデータをソートすることで、特定の値または値の範囲に基づいて低レイテンシで、数十ミリ秒未満でデータを抽出できるようになります。一部の列指向DBMS、例えばSAP HANAやGoogle PowerDrillは、RAM内でのみ動作することができます。このアプローチは、リアルタイム分析のために必要なハードウェアの予算を超える要求を必要とします。
+データを主キーで物理的にソートすることで、特定の値や値の範囲に基づいてデータを低遅延で取り出すことが可能です。SAP HANAやGoogle PowerDrillなどの一部の列指向DBMSは、RAM上でのみ動作することができます。このアプローチは、リアルタイム分析に必要なより大きなハードウェア予算を必要とします。
-ClickHouseは通常のハードドライブで動作するように設計されており、これによりデータストレージあたりのGBのコストが低くなりますが、SSDや追加のRAMもあれば完全に活用されます。
+ClickHouseは通常のハードドライブで動作するように設計されており、データストレージあたりのGBのコストが低いですが、SSDと追加のRAMも利用可能であればフルに使用されます。
## 複数コアでの並列処理 {#parallel-processing-on-multiple-cores}
-大規模なクエリは自然に並列化され、現在のサーバー上で利用可能なすべてのリソースが使用されます。
+大きなクエリは自然に並列化され、現在のサーバーで利用可能なすべてのリソースを利用します。
## 複数サーバーでの分散処理 {#distributed-processing-on-multiple-servers}

-ClickHouseでは、データは異なるシャードに存在できます。各シャードは、フォールトトレランスのために使用されるレプリカのグループである場合があります。すべてのシャードは、ユーザーに透過的にクエリを並列で実行するために使用されます。
+ClickHouseでは、データは異なるシャードに存在することができます。各シャードは、障害耐性のために使用されるレプリカのグループとなることができます。すべてのシャードは、ユーザーに透過的にクエリを並列実行するために使用されます。

-ClickHouseは、ANSI SQL標準とほぼ互換性のある[SQL言語](/sql-reference/)をサポートしています。
+ClickHouseは、ANSI SQL標準とほぼ互換性のあるSQLに基づいた[宣言的クエリ言語](/sql-reference/)をサポートしています。
-サポートされているクエリには、[GROUP BY](../sql-reference/statements/select/group-by.md)、[ORDER BY](../sql-reference/statements/select/order-by.md)、[FROM](../sql-reference/statements/select/from.md)のサブクエリ、[JOIN](../sql-reference/statements/select/join.md)句、[IN](../sql-reference/operators/in.md)オペレーター、[ウィンドウ関数](../sql-reference/window-functions/index.md)、およびスカラーサブクエリが含まれます。

-データはカラムによってだけでなく、ベクトル(カラムの部分)によって処理され、これにより高いCPU効率が達成されます。
+データはカラム単位で保存されるだけでなく、ベクトル(カラムの一部)によって処理されるため、高いCPU効率を達成できます。
## リアルタイムデータ挿入 {#real-time-data-updates}

-## オンラインクエリに適している {#suitable-for-online-queries}
+## オンラインクエリに適した {#suitable-for-online-queries}
-ほとんどのOLAPデータベース管理システムは、サブ秒レイテンシでのオンラインクエリを目指していません。代替システムでは、数十秒または数分のレポート構築時間が許容されることがよくあります。時には、さらに多くの時間がかかり、システムがオフラインでレポートを準備しなければならないことがあります(事前にまたは「後で戻ってくるように」と応答する形で)。
+ほとんどのOLAPデータベース管理システムは、サブ秒のレイテンシでオンラインクエリを目指していません。代替システムでは、数十秒または数分のレポート作成時間がしばしば受け入れられています。時にはそれ以上の時間がかかり、システムがオフラインでレポートを準備せざるを得なくなることがあります(事前にまたは「しばらく待ってください」と応答することによって)。
-ClickHouseでは、「低レイテンシ」とは、クエリが遅延なく処理され、ユーザーインターフェースページが読み込み中のその瞬間に応答を事前に準備しようとせずに行われることを意味します。言い換えれば、オンラインです。
+ClickHouseでは、「低レイテンシ」とは、ユーザーインターフェースページが読み込まれている瞬間に遅延なく処理されることを意味します。つまり、*オンライン*です。
## 近似計算のサポート {#support-for-approximated-calculations}
-ClickHouseは、パフォーマンスのために精度を交換するためのさまざまな方法を提供します:
+ClickHouseはいくつかの方法で精度と性能をトレードオフする方法を提供します:
-1. 異なる値、中央値、パーセンタイルの数の近似計算のための集約関数。
-2. データの部分([SAMPLE](../sql-reference/statements/select/sample.md))に基づいてクエリを実行し、近似結果を得る。この場合、ディスクから取得するデータ量が比例的に少なくなります。
-3. すべてのキーの代わりに、限られた数のランダムキーに対して集約を実行します。データ内のキー分布に関する特定の条件下では、これにより合理的に正確な結果が得られ、より少ないリソースを使用します。

+3. すべてのキーではなく、限られた数のランダムキーに対して集約を実行します。データ内のキー分布の特定の条件下では、これにより合理的に正確な結果が得られ、リソースを少なく使用することができます。
## 適応型結合アルゴリズム {#adaptive-join-algorithm}
-ClickHouseは、複数のテーブルを[JOIN](../sql-reference/statements/select/join.md)する方法を適応的に選択し、ハッシュ結合アルゴリズムを優先し、大きなテーブルが1つ以上ある場合はマージ結合アルゴリズムにフォールバックします。
+ClickHouseは、複数のテーブルを[JOIN](../sql-reference/statements/select/join.md)する方法を適応的に選択し、ハッシュ結合を優先し、1つ以上の大きなテーブルがある場合にはマージ結合にフォールバックします。

+## データレプリケーションおよびデータ整合性サポート {#data-replication-and-data-integrity-support}
-ClickHouseは非同期のマルチマスターレプリケーションを使用しています。すべての利用可能なレプリカに書き込まれた後、残りのレプリカはバックグラウンドでそのコピーを取得します。システムは異なるレプリカ間で同一のデータを維持します。ほとんどの障害後の回復は自動的に、または複雑なケースでは半自動的に行われます。

詳細については、[データレプリケーション](../engines/table-engines/mergetree-family/replication.md)のセクションを参照してください。
## ロールベースのアクセス制御 {#role-based-access-control}
-ClickHouseは、SQLクエリを使用してユーザーアカウント管理を実装し、ANSI SQL標準や一般的なリレーショナルデータベース管理システムで見られるような[ロールベースのアクセス制御の設定](/guides/sre/user-management/index.md)を可能にします。
+ClickHouseは、SQLクエリを使用してユーザーアカウント管理を実装し、ANSI SQL標準および一般的なリレーショナルデータベース管理システムで見られるような[ロールベースのアクセス制御設定](/guides/sre/user-management/index.md)を許可します。
## 欠点と見なされる可能性のある機能 {#clickhouse-features-that-can-be-considered-disadvantages}
-1. 完全なトランザクションがない。
-2. 高い速度と低レイテンシで既に挿入されたデータを変更または削除する機能が欠如している。データをクリーンアップまたは修正するためのバッチ削除や更新が利用可能であり、例えば、[GDPR](https://gdpr-info.eu)に準拠するためにそれが必要です。
-3. スパースインデックスにより、ClickHouseはキーによって単一の行を取得するポイントクエリに対してそれほど効率的ではありません。
+1. 完全なトランザクションがありません。
+2. 高速かつ低レイテンシで挿入済みデータを変更または削除することができません。データをクリーンアップまたは変更するためのバッチ削除や更新が利用可能ですが、たとえば、[GDPR](https://gdpr-info.eu)に準拠するためです。
+3. スパースインデックスにより、ClickHouseはキーによって単一行を取得するポイントクエリに対してそれほど効率的ではありません。

# ClickHouseの歴史 {#clickhouse-history}
-ClickHouseは最初、[Yandex.Metrica](https://metrica.yandex.com/)を支えるために開発されました。[世界で2番目に大きなウェブ解析プラットフォーム](http://w3techs.com/technologies/overview/traffic_analysis/all)であり、今でもそのコアコンポーネントとなっています。データベースには130兆以上のレコードがあり、毎日200億以上のイベントを処理するClickHouseは、非集約データから直接カスタムレポートをリアルタイムで生成することができます。この文書では、ClickHouseの初期開発の目標について簡単に説明します。
+ClickHouseは、[Yandex.Metrica](https://metrica.yandex.com/)を動かすために最初に開発され、[世界で2番目に大きいウェブ解析プラットフォーム](http://w3techs.com/technologies/overview/traffic_analysis/all)であり続けています。データベースには13兆件以上のレコードがあり、1日あたり200億件以上のイベントを処理するClickHouseは、非集約データから即座にカスタムレポートを生成することを可能にします。この記事では、ClickHouseが開発初期において目指していた目標について簡単に説明します。
-Yandex.Metricaは、ユーザーが定義した任意のセグメントに基づいて、ヒット数やセッションに基づいたカスタマイズレポートをリアルタイムで構築します。これを行うためには、ユニークユーザー数のような複雑な集約を構築する必要があることが多く、新しいデータはレポート作成のためにリアルタイムで到着します。

-2014年4月の時点で、Yandex.Metricaは1日あたり約120億のイベント(ページビューとクリック)を追跡していました。これらのすべてのイベントは、カスタムレポートを作成するために保存する必要がありました。単一のクエリは、数百ミリ秒内に100万行をスキャンする必要がある場合もあれば、数秒で数億行をスキャンする必要がある場合もありました。

## Yandex.Metricaおよびその他のYandexサービスでの使用 {#usage-in-yandex-metrica-and-other-yandex-services}
-ClickHouseはYandex.Metricaで多くの目的に使用されています。主なタスクは、非集約データを使用してオンラインモードでレポートを生成することです。20.3兆行以上をデータベースに保存している374台のサーバークラスターを使用しています。圧縮データのボリュームは約2PBで、重複やレプリカを考慮していません。非圧縮データ(TSV形式)のボリュームは約17PBに達します。

## 集約データと非集約データ {#aggregated-and-non-aggregated-data}
-統計を効果的に計算するには、データを集約する必要があるという広く親しまれている意見があります。これはデータのボリュームを減らすためです。
+統計を効果的に計算するには、データを集約する必要があるという広く認識された意見があります。これは、データの量を減らすためです。
-しかし、データ集約には多くの制約が伴います:
+しかし、データの集約には多くの制限があります:
-- 必要なレポートの事前定義されたリストが必要です。
+- 必要なレポートの事前定義リストが必要です。
- ユーザーはカスタムレポートを作成できません。
-- 多くの異なるキーで集約する場合、データ量はほとんど減少しないため、集約は無意味です。
-- レポートの数が多い場合、集約のバリエーションが多すぎ(組合せ爆発)ます。
-- 高いカーディナリティのキー(URLなど)を集約する場合、データのボリュームはあまり減少しません(2倍未満)。
-- このため、集約によってデータのボリュームが縮小するのではなく、増加する可能性があります。
-- ユーザーは私たちが生成するすべてのレポートを表示しません。その計算の多くは無意味です。
-- 様々な集約によってデータの論理的整合性が損なわれる可能性があります。
+- 多くの異なるキーを集約すると、データ量はほとんど減少しないため、集約は無駄です。
+- 大量のレポートに対して、集約のバリエーションが多すぎます(組み合わせ爆発)。
+- 高い基数を持つキー(例えばURL)を集約する際、データ量はあまり減少しません(2倍未満)。
+- このため、集約のあるデータ量はむしろ増加する可能性があります。
+- ユーザーは、我々が生成するすべてのレポートを閲覧しません。これらの計算の大部分は無駄です。
+- 様々な集約のためにデータの論理的一貫性が損なわれる可能性があります。
-何も集約せず、非集約データで作業する場合、計算量を減少させることができます。
+何も集約せずに非集約データで作業をすると、計算量が減少するかもしれません。
-しかし、集約を行うことで、大部分の作業がオフラインで行われ、比較的落ち着いて完了します。対照的にオンライン計算は、ユーザーが結果を待っているため、できるだけ早く計算する必要があります。

-Yandex.Metricaには、Metrageというデータを集約するための専門システムがあり、大部分のレポートで使用されていました。2009年からは、非集約データ用の専門OLAPデータベースOLAPServerも使用されており、これは以前はレポートビルダーに使用されていました。OLAPServerは非集約データに対してはうまく機能しましたが、すべてのレポートに使用することを妨げる多くの制約がありました。これには、データ型へのサポートがない(数字のみ)ことや、リアルタイムでデータを逐次更新することができない(毎日のデータ書き換えにしかできなかった)ことが含まれています。OLAPServerはDBMSではなく、専門DBです。

-
-
-このチュートリアルでは、[ローカル ClickHouse サーバー](../getting-started/install/install.mdx)が既にセットアップされている前提です。
-
-このチュートリアルを通じて、シンプルな ClickHouse クラスターのセットアップ方法を学びます。小規模ですが、フォールトトレラントでスケーラブルです。その後、サンプルデータセットの1つを使用してデータを埋め込み、いくつかのデモクエリを実行します。
-
-## クラスター展開 {#cluster-deployment}
-
-この ClickHouse クラスターは均質なクラスターになります。手順は以下の通りです:
-
-1. クラスター内のすべてのマシンに ClickHouse サーバーをインストールします
-2. 設定ファイル内でクラスターの設定を行います
-3. 各インスタンスにローカルテーブルを作成します
-4. [分散テーブル](../engines/table-engines/special/distributed.md)を作成します
-
-[分散テーブル](../engines/table-engines/special/distributed.md)は、ClickHouse クラスター内のローカルテーブルへの「ビュー」の一種です。分散テーブルからの SELECT クエリは、クラスター内のすべてのシャードのリソースを使用して実行されます。複数のクラスターに対して設定を指定し、異なるクラスターのビューを提供するために複数の分散テーブルを作成することができます。
-
-以下は、1つのレプリカを持つ3つのシャードからなるクラスターの設定例です:
