+/** BFloat16 is a 16-bit floating point type, which has the same number (8) of exponent bits as Float32.
+  * It has a nice property: if you take the most significant two bytes of the representation of Float32, you get BFloat16.
+  * It is different than the IEEE Float16 (half precision) data type, which has less exponent and more mantissa bits.
+  *
+  * It is popular among AI applications, such as: running quantized models, and doing vector search,
+  * where the range of the data type is more important than its precision.
+  *
+  * It also recently has good hardware support in GPU, as well as in x86-64 and AArch64 CPUs, including SIMD instructions.
+  * But it is rarely utilized by compilers.
+  *
+  * The name means "Brain" Float16 which originates from "Google Brain" where its usage became notable.
+  * It is also known under the name "bf16". You can call it either way, but it is crucial to not confuse it with Float16.
+
+  * Here is a manual implementation of this data type. Only required operations are implemented.
+  * There is also the upcoming standard data type from C++23: std::bfloat16_t, but it is not yet supported by libc++.
+  * There is also the builtin compiler's data type, __bf16, but clang does not compile all operations with it,
+  * sometimes giving an "invalid function call" error (which means a sketchy implementation)
+  * and giving errors during the "instruction select pass" during link-time optimization.
+  *
+  * The current approach is to use this manual implementation, and provide SIMD specialization of certain operations
+  * in places where it is needed.

+### ClickHouse release v24.10.2.80-stable (96b80057159) FIXME as compared to v24.10.1.2812-stable (9cd0a3738d5)
+
+#### Backward Incompatible Change
+* Backported in [#71363](https://github.com/ClickHouse/ClickHouse/issues/71363): Fix possible error `No such file or directory` due to unescaped special symbols in files for JSON subcolumns. [#71182](https://github.com/ClickHouse/ClickHouse/pull/71182) ([Pavel Kruglov](https://github.com/Avogar)).
+
+#### Performance Improvement
+* Backported in [#71852](https://github.com/ClickHouse/ClickHouse/issues/71852): Improve the performance and accuracy of system.query_metric_log collection interval by reducing the critical region. [#71473](https://github.com/ClickHouse/ClickHouse/pull/71473) ([Pablo Marcos](https://github.com/pamarcos)).
+
+#### Improvement
+* Backported in [#71495](https://github.com/ClickHouse/ClickHouse/issues/71495): Enable `parallel_replicas_local_plan` by default. Building a full-fledged local plan on the query initiator improves parallel replicas performance with less resource consumption, provides opportunities to apply more query optimizations. [#70171](https://github.com/ClickHouse/ClickHouse/pull/70171) ([Igor Nikonov](https://github.com/devcrafter)).
+* Backported in [#71985](https://github.com/ClickHouse/ClickHouse/issues/71985): Fixes RIGHT / FULL joins in queries with parallel replicas. Now, RIGHT joins can be executed with parallel replicas (right table reading is distributed). FULL joins can't be parallelized among nodes, - executed locally. [#71162](https://github.com/ClickHouse/ClickHouse/pull/71162) ([Igor Nikonov](https://github.com/devcrafter)).
+* Backported in [#71670](https://github.com/ClickHouse/ClickHouse/issues/71670): When user/group is given as ID, the `clickhouse su` fails. This patch fixes it to accept `UID:GID` as well. ### Documentation entry for user-facing changes. [#71626](https://github.com/ClickHouse/ClickHouse/pull/71626) ([Mikhail f. Shiryaev](https://github.com/Felixoid)).
+* Backported in [#71940](https://github.com/ClickHouse/ClickHouse/issues/71940): Update `HostResolver` 3 times in a `history` period. [#71863](https://github.com/ClickHouse/ClickHouse/pull/71863) ([Sema Checherinda](https://github.com/CheSema)).
+* Backported in [#71922](https://github.com/ClickHouse/ClickHouse/issues/71922): Allow_reorder_prewhere_conditions is on by default with old compatibility settings. [#71867](https://github.com/ClickHouse/ClickHouse/pull/71867) ([Raúl Marín](https://github.com/Algunenano)).
+
+#### Bug Fix (user-visible misbehavior in an official stable release)
+* Backported in [#71588](https://github.com/ClickHouse/ClickHouse/issues/71588): Fix mismatched aggreage function name of quantileExactWeightedInterpolated. The bug was introduced in https://github.com/ClickHouse/ClickHouse/pull/69619. cc @Algunenano. [#71168](https://github.com/ClickHouse/ClickHouse/pull/71168) ([李扬](https://github.com/taiyang-li)).
+* Backported in [#71357](https://github.com/ClickHouse/ClickHouse/issues/71357): Fix bad_weak_ptr exception with Dynamic in functions comparison. [#71183](https://github.com/ClickHouse/ClickHouse/pull/71183) ([Pavel Kruglov](https://github.com/Avogar)).
+* Backported in [#71467](https://github.com/ClickHouse/ClickHouse/issues/71467): Fix bug of memory usage increase if enable_filesystem_cache=1, but disk in storage configuration did not have any cache configuration. [#71261](https://github.com/ClickHouse/ClickHouse/pull/71261) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Backported in [#71355](https://github.com/ClickHouse/ClickHouse/issues/71355): Fix possible error "Cannot read all data" erros during deserialization of LowCardinality dictionary from Dynamic column. [#71299](https://github.com/ClickHouse/ClickHouse/pull/71299) ([Pavel Kruglov](https://github.com/Avogar)).
+* Backported in [#71324](https://github.com/ClickHouse/ClickHouse/issues/71324): Fix incomplete cleanup of parallel output format in the client. [#71304](https://github.com/ClickHouse/ClickHouse/pull/71304) ([Raúl Marín](https://github.com/Algunenano)).
+* Backported in [#71466](https://github.com/ClickHouse/ClickHouse/issues/71466): Added missing unescaping in named collections. Without fix clickhouse-server can't start. [#71308](https://github.com/ClickHouse/ClickHouse/pull/71308) ([MikhailBurdukov](https://github.com/MikhailBurdukov)).

-When a `SELECT` query has the `GROUP BY` clause or at least one aggregate function, ClickHouse (in contrast to MySQL) requires that all expressions in the `SELECT`, `HAVING`, and `ORDER BY` clauses be calculated from keys or from aggregate functions. In other words, each column selected from the table must be used either in keys or inside aggregate functions. To get behavior like in MySQL, you can put the other columns in the `any` aggregate function.

+SupersetデプロイメントでClickHouse Connectドライバーを利用可能にするために、ローカルのrequirementsファイルに追加します：
+
+```bash
+echo "clickhouse-connect" >> ./docker/requirements-local.txt
+```
+
+## MapBox
+
+これは任意です。MapBox APIキーなしでSupersetで位置データをプロットできますが、キーを追加するべきというメッセージが表示され、地図の背景画像が欠けます（データポイントのみが表示され、地図の背景は表示されません）。MapBoxは無料のティアを提供していますので、利用したい場合はぜひご利用ください。
+
+ガイドが作成するサンプルの可視化の一部は、例えば経度や緯度データなどの位置情報を使用します。SupersetはMapBoxマップのサポートを含んでいます。MapBoxの可視化を使用するには、MapBox APIキーが必要です。[MapBoxの無料ティア](https://account.mapbox.com/auth/signup/)にサインアップし、APIキーを生成してください。
+
+APIキーをSupersetで利用可能にします：
+
+```bash
+echo "MAPBOX_API_KEY=pk.SAMPLE-Use-your-key-instead" >> docker/.env-non-dev
+```
+
+## Supersetバージョン2.0.0をデプロイ
+
+リリース2.0.0をデプロイするには、以下を実行します：
+
+```bash
+git checkout 2.0.0
+TAG=2.0.0 docker-compose -f docker-compose-non-dev.yml pull
+TAG=2.0.0 docker-compose -f docker-compose-non-dev.yml up

+## ClickHouse Cloudで複数のMySQLユーザーを作成する
+
+デフォルトでは、`mysql4<subdomain>`という組み込みユーザーがあり、これは`default`ユーザーと同じパスワードを使用します。`<subdomain>`部分はあなたのClickHouse Cloudホスト名の最初のセグメントです。このフォーマットは、安全な接続を実装しているが[TLSハンドシェイクでSNI情報を提供しない](https://www.cloudflare.com/learning/ssl/what-is-sni)ツール（MySQLコンソールクライアントがその一例）で作業するために必要です。この場合、ユーザー名に追加のヒントを含めずには内部ルーティングを行うことができません。
+
+これにより、MySQLインターフェースで使用する新しいユーザーを作成する際には、`mysql4<subdomain>_<username>`のフォーマットを使用することを_強くお勧めします_。ここで、`<subdomain>`はあなたのCloudサービスを識別するためのヒントであり、`<username>`は選択した任意のサフィックスです。
+
+:::tip
+ClickHouse Cloudホスト名が`foobar.us-east1.aws.clickhouse.cloud`の場合、`<subdomain>`部分は`foobar`に相当し、カスタムMySQLユーザー名は`mysql4foobar_team1`のようになります。
+:::
+
+MySQLインターフェースを使用するために追加のユーザーを作成することができます。例えば、追加の設定を適用する必要がある場合などです。
+
+1. オプション - カスタムユーザーに適用する[設定プロフィール](https://clickhouse.com/docs/ja/sql-reference/statements/create/settings-profile)を作成します。たとえば、後で作成するユーザーで接続するときにデフォルトで適用される追加設定を持つ`my_custom_profile`:
+
+    ```sql
+    CREATE SETTINGS PROFILE my_custom_profile SETTINGS prefer_column_name_to_alias=1;
+    ```
+
+    `prefer_column_name_to_alias`は単なる例として使用されます。ここに他の設定を使用することもできます。
+2. 以下のフォーマットを使用して[ユーザーを作成](https://clickhouse.com/docs/ja/sql-reference/statements/create/user)します: `mysql4<subdomain>_<username>` ([上記参照](#creating-multiple-mysql-users-in-clickhouse-cloud))。パスワードはダブルSHA1形式である必要があります。例:
+
+    ```sql
+    CREATE USER mysql4foobar_team1 IDENTIFIED WITH double_sha1_password BY 'YourPassword42$';
+    ```
+
+    または、このユーザーにカスタムプロフィールを使用したい場合:
+
+    ```sql
+    CREATE USER mysql4foobar_team1 IDENTIFIED WITH double_sha1_password BY 'YourPassword42$' SETTINGS PROFILE 'my_custom_profile';
+    ```
+
+    ここで、`my_custom_profile`は前に作成したプロフィールの名前です。
+3. 新しいユーザーに必要なアクセス権を付与して、目的のテーブルまたはデータベースと対話できるようにします。[権限を付与](https://clickhouse.com/docs/ja/sql-reference/statements/grant)する例として、たとえば`system.query_log`のみのアクセスを付与したい場合:
+
+    ```sql
+    GRANT SELECT ON system.query_log TO mysql4foobar_team1;
+    ```
+
+4. 作成したユーザーを使用して、MySQLインターフェースでClickHouse Cloudサービスに接続します。
+
+### ClickHouse Cloudでの複数のMySQLユーザーのトラブルシューティング
+
+新しいMySQLユーザーを作成し、MySQL CLIクライアントで接続しているときに以下のエラーが表示された場合：
+
+```
+ERROR 2013 (HY000): Lost connection to MySQL server at 'reading authorization packet', system error: 54
+```
+
+この場合、ユーザー名が`mysql4<subdomain>_<username>`形式に従っていることを確認してください。[上記](#creating-multiple-mysql-users-in-clickhouse-cloud)で説明されています。

+
+MySQLインターフェースを利用するユーザーには、[二重SHA1パスワード暗号化](https://clickhouse.com/docs/ja/operations/settings/settings-users#user-namepassword)を使用することが**必要**です。
+
+シェルから二重SHA1で暗号化されたランダムパスワードを生成するには以下を実行してください：
+
+```shell
+PASSWORD=$(base64 < /dev/urandom | head -c16); echo "$PASSWORD"; echo -n "$PASSWORD" | sha1sum | tr -d '-' | xxd -r -p | sha1sum | tr -d '-'

+
+出力は以下のようになります：
+
+```
+LZOQYnqQN4L/T6L0
+fbc958cc745a82188a51f30de69eebfc67c40ee4
+```
+
+最初の行は生成されたパスワードで、2行目はClickHouseの設定に使用するハッシュです。
+
+以下は生成されたハッシュを使用する`mysql_user`の設定例です：
+
+`/etc/clickhouse-server/users.d/mysql_user.xml`
+
+```xml

+    </mysql_user>
+</users>
+```
+
+`password_double_sha1_hex` エントリを自分で生成した二重SHA1ハッシュに置き換えてください。
+
+さらに、BIツールがMySQLコネクタを使用する際にデータベーススキーマを適切に調査できるように、`SHOW [FULL] COLUMNS` クエリの結果でMySQLネイティブタイプを表示するために、`use_mysql_types_in_show_columns`を使用することを推奨します。
+
+例えば：
+
+`/etc/clickhouse-server/users.d/mysql_user.xml`
+
+```xml

+    <default>
+        <use_mysql_types_in_show_columns>1</use_mysql_types_in_show_columns>
+    </default>
+</profiles>
+```
+
+または、デフォルト以外の異なるプロファイルに割り当てることもできます。
+
+`mysql` バイナリが利用可能であれば、コマンドラインから接続をテストできます。以下は、サンプルのユーザー名 (`mysql_user`) とパスワード (`LZOQYnqQN4L/T6L0`) を使用したコマンドです：
+
+```bash

+## 用語集
+### レプリカ
+データのコピー。ClickHouseは常にデータの少なくとも1つのコピーを持っているため、**レプリカ**の最小数は1です。これは重要なポイントで、元のデータをレプリカとして数えることに慣れていないかもしれませんが、ClickHouseのコードとドキュメントではその用語が使用されています。データの2番目のレプリカを追加することで、フォールトトレランスを提供できます。
+
+### シャード
+データのサブセット。ClickHouseは常にデータの少なくとも1つのシャードを持っているので、データを複数のサーバーに分散しない場合、データは1つのシャードに格納されます。データを複数のサーバーに分散してシャーディングすることは、単一サーバーの容量を超えた場合に負荷を分散するために利用できます。宛先サーバーは**シャーディングキー**によって決まり、分散テーブルを作成する際に定義されます。シャーディングキーはランダムなものか、[ハッシュ関数](https://clickhouse.com/docs/ja/sql-reference/functions/hash-functions)の出力として定義することができます。シャーディングを含むデプロイメント例では、シャーディングキーとして`rand()`を使用し、いつどのようにして異なるシャーディングキーを選択するかについてのさらなる情報を提供します。

+### 分散調整
+ClickHouse Keeperは、データのレプリケーションと分散DDLクエリの実行のための調整システムを提供します。ClickHouse KeeperはApache ZooKeeperと互換性があります。

+
+## 非管理者ユーザー
+
+ユーザーは必要な権限を持ち、全員が管理者であるべきではありません。このドキュメントの残りの部分では、例のシナリオと必要な役割を提供します。
+
+### 準備
+
+例で使用されるテーブルとユーザーを作成します。
+
+#### サンプルデータベース、テーブル、および行の作成
+
+1. テストデータベースを作成
+
+   ```sql
+   CREATE DATABASE db1;
+   ```
+
+2. テーブルを作成
+
+   ```sql
+   CREATE TABLE db1.table1 (
+       id UInt64,
+       column1 String,
+       column2 String
+   )
+   ENGINE MergeTree
+   ORDER BY id;
+   ```
+
+3. サンプル行でテーブルを埋める
+
+   ```sql
+   INSERT INTO db1.table1
+       (id, column1, column2)
+   VALUES
+       (1, 'A', 'abc'),
+       (2, 'A', 'def'),
+       (3, 'B', 'abc'),
+       (4, 'B', 'def');
+   ```
+
+4. テーブルを確認する：
+
+   ```sql
+   SELECT *
+   FROM db1.table1
+   ```
+
+   ```response
+   Query id: 475015cc-6f51-4b20-bda2-3c9c41404e49
+
+   ┌─id─┬─column1─┬─column2─┐
+   │  1 │ A       │ abc     │
+   │  2 │ A       │ def     │
+   │  3 │ B       │ abc     │
+   │  4 │ B       │ def     │
+   └────┴─────────┴─────────┘
+   ```
+
+5. 特定のカラムへのアクセスを制限することを示すために使用される通常のユーザーを作成：
+
+   ```sql
+   CREATE USER column_user IDENTIFIED BY 'password';
+   ```
+
+6. 特定の値を持つ行へのアクセスを制限することを示すために使用される通常のユーザーを作成：
+   ```sql
+   CREATE USER row_user IDENTIFIED BY 'password';
+   ```
+
+#### 役割の作成
+
+この例を使って：
+
+- カラムや行、異なる権限のための役割を作成します
+- 役割に権限を付与します
+- ユーザーを各役割に割り当てます
+
+役割は、各ユーザーを個別に管理する代わりに、特定の権限を持つユーザーのグループを定義するために使用されます。
+
+1.  `db1` データベースおよび `table1` において、`column1` のみを閲覧できるユーザーの役割を作成：
+
+    ```sql
+    CREATE ROLE column1_users;
+    ```
+
+2.  `column1` のみが閲覧可能な権限を設定
+
+    ```sql
+    GRANT SELECT(id, column1) ON db1.table1 TO column1_users;
+    ```
+
+3.  `column_user` ユーザーを `column1_users` 役割に追加
+
+    ```sql
+    GRANT column1_users TO column_user;
+    ```
+
+4.  `column1` に `A` を含む行のみを閲覧できるユーザーの役割を作成
+

+7.  データベースとテーブルへの権限を設定
+
+    ```sql
+    GRANT SELECT(id, column1, column2) ON db1.table1 TO A_rows_users;
+    ```
+
+8.  他の役割に対してもすべての行にアクセスできるように明示的な権限を付与
+
+    ```sql
+    CREATE ROW POLICY allow_other_users_filter 
+    ON db1.table1 FOR SELECT USING 1 TO clickhouse_admin, column1_users;
+    ```
+
+    :::note
+    テーブルにポリシーをアタッチすると、システムはそのポリシーを適用し、定義されたユーザーと役割のみがそのテーブルでの操作を行うことができます。その他のユーザーは操作を拒否されます。制限された行ポリシーが他のユーザーに適用されないようにするため、他のユーザーと役割が通常または他のタイプのアクセスを持つことを許可する別のポリシーを定義する必要があります。

+## ユーザーと役割の変更
+
+ユーザーは必要な権限の組み合わせに対して複数の役割を割り当てることができます。複数の役割を使用する場合、システムは役割を組み合わせて権限を決定し、その結果、役割の権限が累積されます。
+
+例えば、1つの `role1` が `column1` のみの選択を許可し、`role2` が `column1` と `column2` の選択を許可する場合、ユーザーは両方のカラムにアクセスできます。
+
+1. 管理者アカウントを使用して、デフォルトの役割で行とカラムの両方を制限する新しいユーザーを作成
+
+   ```sql
+   CREATE USER row_and_column_user IDENTIFIED BY 'password' DEFAULT ROLE A_rows_users;
+   ```
+
+2. `A_rows_users` 役割に対する以前の権限を削除
+
+   ```sql
+   REVOKE SELECT(id, column1, column2) ON db1.table1 FROM A_rows_users;
+   ```
+
+3. `A_row_users` 役割に `column1` のみの選択を許可
+
+   ```sql
+   GRANT SELECT(id, column1) ON db1.table1 TO A_rows_users;
+   ```
+
+4. `row_and_column_user` でClickHouseクライアントにログイン
+
+   ```
+   clickhouse-client --user row_and_column_user --password password;
+   ```
+
+5. すべてのカラムでテスト：
+
+   ```sql
+   SELECT *
+   FROM db1.table1
+   ```
+
+   ```response
+   Query id: 8cdf0ff5-e711-4cbe-bd28-3c02e52e8bc4
+
+   0 rows in set. Elapsed: 0.005 sec.
+
+   Received exception from server (version 22.3.2):
+   Code: 497. DB::Exception: Received from localhost:9000. 
+   DB::Exception: row_and_column_user: Not enough privileges. 
+   To execute this query it's necessary to have grant 
+   SELECT(id, column1, column2) ON db1.table1. (ACCESS_DENIED)
+   ```
+
+6. 制限されたカラムでテスト：
+
+   ```sql
+   SELECT
+       id,
+       column1
+   FROM db1.table1
+   ```
+
+   ```response
+   Query id: 5e30b490-507a-49e9-9778-8159799a6ed0
+
+   ┌─id─┬─column1─┐
+   │  1 │ A       │
+   │  2 │ A       │
+   └────┴─────────┘
+   ```
