    从对象存储导入文件

    +

    概述

    +

    S3（Simple Storage Service）对象存储是指亚马逊的简单存储服务。你还可以使用与 S3 兼容的对象存储来存储几乎任何类型和大小的数据，包括数据湖、云原生应用程序和移动应用程序。如果你不熟悉 S3 对象服务，你可以在 AWS 中查找一些基本介绍。

    +

    AWS S3 十多年来一直非常成功，因此它成为了对象存储的标准。因此几乎所有主流公有云厂商都提供了兼容 S3 的对象存储服务。

    +

    MatrixOne 支持将文件从 S3 兼容的对象存储服务加载到数据库中。MatrixOne 支持 AWS 和国内主流云厂商（阿里云、腾讯云）。

    +

    在 MatrixOne 中，有两种方法可以从 S3 兼容的对象存储中导入数据：

    +
      +
    • 使用带有 s3option 的 Load data 将文件加载到 MatrixOne 中。此方法会将数据加载到 MatrixOne 中，所有接下来的查询都将在 MatrixOne 中进行。
      • +
    • 创建一个带有 s3option 映射到 S3 文件的 “外部表”，并直接查询这个外部表。该方法允许通过 S3 兼容的对象存储服务进行数据访问；每个查询的网络延迟都将被计算在内。
      • +
    +

    同时，如果要导入来自公有云（例如 AWS S3 或阿里云 OSS）的数据，需要具备相应的访问权限。通常有两种方式可供选择：角色访问和密钥访问。

    +
      +
    • +

      角色访问：在存储数据的公有云账户中创建一个特定角色，该角色被授权让 MatrixOne 应用使用以获取数据的权限。这种方式更为安全，同时也更加便于管理和调整数据访问权限。

      +
      • +
    • +

      密钥访问：通过使用拥有数据访问权限的用户的 Access Key ID 和 Secret Access Key 来获取数据。这种方式相对简单，但不够安全，因为一旦 Access Key ID 和 Secret Access Key 泄露，可能会造成严重后果。

      +
      • +
    +

    方式 1: LOAD DATA

    +

    语法结构

    +
    LOAD DATA
+    | URL s3options {"endpoint"='<string>', "access_key_id"='<string>', "secret_access_key"='<string>', "bucket"='<string>', "role_arn"='xxxx', "external_id"='yyy', "filepath"='<string>', "region"='<string>', "compression"='<string>'}
+    INTO TABLE tbl_name
+    [{FIELDS | COLUMNS}
+        [TERMINATED BY 'string']
+        [[OPTIONALLY] ENCLOSED BY 'char']
+        [ESCAPED BY 'char']
+    ]
+    [IGNORE number {LINES | ROWS}]
+    [PARALLEL {'TRUE' | 'FALSE'}]
+
    +

    参数说明

    + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
    参数描述
    endpoint可以连接到对象存储服务的 URL。例如：s3.us-west-2.amazonaws.com
    Note: LOAD DATA 仅支持获取 AWS 对象存储服务和阿里云外网对象存储服务的 URL。
    access_key_idAccess key ID。用于身份验证的访问密钥ID。
    secret_access_keySecret access key。与访问密钥ID相关联的密钥。
    bucket指定S3存储中的桶（Bucket）
    role_arnAWS角色的Amazon资源名称（ARN），通常用于跨账户访问。
    Note: 推荐使用角色访问的方式。如果你选择角色访问的方式，则无需填写 access_key_id 和 secret_access_key，仅填写参数 role_arn。
    external_id用于与角色ARN一起使用的外部ID。
    filepath相对文件路径。 /files/*.csv 支持正则表达式。
    region对象存储服务区域
    compressionS3 文件的压缩格式。如果为空或 "none"，则表示未压缩的文件。支持的字段或压缩格式为“auto”、“none”、“gzip”、“bz2”和“lz4”。
    +

    其他参数与通用 LOAD DATA 参数相同，更多信息，参见 LOAD DATA。

+
    +
    +

    Note

    +

    MatrixOne 提供了 S3 验证信息的安全保证，例如 access_key_id 和 secret_access_key 敏感信息在系统表（statement_info）记录里将被隐藏，保证你的账户安全。

    教程：使用 S3 文件创建外部表

    +

    本教程将指导你完成使用来自 AWS S3 的. csv 文件创建外部表的整个过程。

    +
    +

    Note

    +

    由于帐户隐私，此代码示例不会显示帐户信息，例如 access_key_id 和 secret_access_key。 +你可以阅读本文档以了解主要步骤；具体数据和账户信息将不会显示。

    +
    +
      +
    1. +

      下载数据文件。进入 AWS S3 > buckets，创建一个具有公共访问权限的存储桶 test-loading 并上传文件 char_varchar_1.csv。

      +

      +

      public block

      +
      2. +
    2. +

      获取或创建你的 AWS Access key。输入 Your Account Name > Security Credentials，获取你现有的访问密钥或创建一个新的访问密钥。

      +

      +

      Access Key

      +

      你可以从下载的凭据或此网页中获取 Access key 和 Secret access key。

      +

      Retrieve Access Key

      +
      3. +
    3. +

      启动 MySQL 客户端，指定 S3 文件到外部表：

      +
      create database db;
+use db;
+drop table if exists t1;
+create external table t1(col1 char(225), col2 varchar(225), col3 text, col4 varchar(225)) url s3option{"endpoint"='s3.us-east-1.amazonaws.com', "access_key_id"='XXXXXX', "secret_access_key"='XXXXXX', "bucket"='test-loading', "filepath"='char_varchar_1.csv', "region"='us-east-1', "compression"='none'} fields terminated by ',' enclosed by '\"' lines terminated by '\n';
+
      +
      4. +
    4. +

      导入成功后，你可以运行如下 SQL 语句查看导入数据的结果。你将可以看到查询速度明显慢于从本地表查询。

      +
      select * from t1;

    分区裁剪

    +

    概述

    +

    分区裁剪是一种用于查询优化的方法，仅当目标表为分区表的情况。通过分析查询语句中的过滤条件，分区裁剪选择可能满足条件的分区，从而避免扫描不匹配条件的分区，大幅减少所需计算的数据量。

    +

    例如：

    +
    CREATE TABLE t1 (
+    col1 INT NOT NULL,
+    col2 DATE NOT NULL,
+    col3 INT NOT NULL,
+    PRIMARY KEY(col1, col3)
+) PARTITION BY KEY(col1, col3) PARTITIONS 4;
+

+(5, '1981-09-28', 7654),

    +

    该查询通过裁剪分区，仅扫描了 p0 和 p2 分区。

    +

    分区裁剪在 KEY 分区表上的应用

    +

    适用的 KEY 分区表场景

    +

    只有与分区键匹配的等值比较查询条件才能支持 KEY 分区表的裁剪。

    +
    CREATE TABLE t1 (
+    col1 INT NOT NULL,
+    col2 DATE NOT NULL,
+    col3 INT PRIMARY KEY
+) PARTITION BY KEY(col3) PARTITIONS 4;
+
+mysql> EXPLAIN SELECT * FROM t1 WHERE col3 = 7990 OR col3 = 7988;
++-------------------------------------------------------------------+
+| QUERY PLAN                                                        |
++-------------------------------------------------------------------+
+| Project                                                           |
+|   ->  Table Scan on db1.t1                                        |
+|         Hit Partition: p0, p1                                     |
+|         Filter Cond: ((t1.col3 = 7990) or (t1.col3 = 7988))       |
+|         Block Filter Cond: ((t1.col3 = 7990) or (t1.col3 = 7988)) |
++-------------------------------------------------------------------+
+5 rows in set (0.00 sec)
+
    +

    在这个 SQL 中，条件 col3 = 7990 可以确定所有结果都位于分区 p0 上。条件 col3 = 7988 可以确定所有结果都位于分区 p1 上。由于这两个条件的关系是 OR，因此只需要扫描 p0 和 p1 两个分区，分区裁剪的结果是 p0 和 p1。

    +

    不适用的 KEY 分区表场景

    +

    场景一

    +

    无法确定查询结果在一个分区内的条件，如 between、> < >= <= 等条件，无法使用分区裁剪优化。

    +
    mysql> EXPLAIN SELECT * FROM t1 WHERE col3 >= 7782;
++----------------------------------------------+
+| QUERY PLAN                                   |

+| Project                                      |
+|   ->  Table Scan on db1.t1                   |
+|         Hit Partition: all partitions        |
+|         Filter Cond: (t1.col3 >= 7782)       |
+|         Block Filter Cond: (t1.col3 >= 7782) |
++----------------------------------------------+
+5 rows in set (0.00 sec)
+
    +

    场景二

    +

    对于只能在执行计划生成阶段获取过滤条件的场景，无法利用分区裁剪优化。

    +
    mysql> EXPLAIN SELECT * FROM t1 WHERE col3 = (SELECT col3 FROM t2 WHERE t1.col3 = t2.col3 AND t2.col1 < 5);
++------------------------------------------------------+
+| QUERY PLAN                                           |

+|         Filter Cond: (t1.col3 = t2.col3
+
+)             |
+|         ->  Join                                     |
+|               Join Type: SINGLE                      |
+|               Join Cond: (t1.col3 = t2.col3)         |
+|               ->  Table Scan on db1.t1               |
+|                     Hit Partition: all partitions    |
+|               ->  Table Scan on db1.t2               |
+|                     Hit Partition: all partitions    |
+|                     Filter Cond: (t2.col1 < 5)       |
+|                     Block Filter Cond: (t2.col1 < 5) |
++------------------------------------------------------+
+12 rows in set (0.00 sec)
+
    +

    这个查询每读取一行数据，都会从子查询中获取结果并构建等值过滤条件 col3 = ?。然而，分区裁剪只在查询计划生成阶段生效，而不是执行阶段，因此无法进行分区裁剪。

    +

    分区裁剪在 Hash 分区表上的应用

    +

    适用的 HASH 分区表场景

    +

    Hash 分区表的使用方式与 Key 分区表基本相同，只有等值比较查询条件才能支持 Hash 分区表的裁剪。

    +

    +

    在这个 SQL 中，由于分区表的分区键为 store_id，条件 store_id = 10 可以确定所有结果都在一个分区中。数值 10 经过 Hash 后确定位于分区 p0 中。因此只需要扫描分区 p0，无需访问绝对不包含相关结果的 p1、p2、p3 分区。从执行计划中可见，只出现一个 TableScan 算子，其中指定了 Hit Partition 为 p0，确保了分区裁剪的生效。

    +

    不适用的 HASH 分区表场景

    +

    场景一

    +

    无法确定查询结果在一个分区内的条件，如 between、> < >= <= 等条件，无法使用分区裁剪优化。

    +
    CREATE TABLE employees (

++------------------------------------------------+
+4 rows in set (0.00 sec)
+
    +

    在这个 SQL 中，条件 store_id > 15 无法确定对应的 Hash 分区，因此无法使用分区裁剪优化。

    +

    场景二

    +

    对于只能在执行计划生成阶段获取过滤条件的场景，无法利用分区裁剪优化。

    +
    mysql> EXPLAIN SELECT * FROM t1 WHERE col1 = (SELECT store_id FROM employees WHERE employees.store_id = t1.col1 AND employees.id = 10010);

++---------------------------------------------------------+
+11 rows in set (0.01 sec)
+
    +

    这个查询每读取一行数据，都会从子查询中获取结果并构建等值过滤条件 col3 = ?，然而，分区裁剪仅在查询计划生成阶段生效，而不是执行阶段，因此无法进行分区裁剪。

    +

    场景三

    +

    目前，不支持将函数表达式用作 Hash 分区表达式的分区裁剪。

    +
    CREATE TABLE t3 (

    分区剪裁的性能调优示例

    +

    示例 1: KEY 分区表的等值条件

    +
    CREATE TABLE t1 (
+    col1 INT NOT NULL,
+    col2 DATE NOT NULL,
+    col3 INT NOT NULL,
+    PRIMARY KEY(col1, col3)
+) PARTITION BY KEY(col1, col3) PARTITIONS 4;
+
+mysql> EXPLAIN SELECT * FROM t1 WHERE col1 = 1 AND col3 = 7369;
++------------------------------------------------+
+| QUERY PLAN                                     |
++------------------------------------------------+
+| Project                                        |
+|   ->  Table Scan on db2.t1                     |
+|         Hit Partition: p0                      |
+|         Filter Cond: ((t1.col1 = 1) and (t1.col3 = 7369)) |
++------------------------------------------------+
+5 rows in set (0.00 sec)
+
    +

    这个查询经过分区裁剪后，只会访问分区 p0，因为查询条件与 p0 中的数据匹配。

    +

    示例 2: KEY 分区表的 OR 条件

    +
    mysql> EXPLAIN SELECT * FROM t1 WHERE (col1 = 1 AND col3 = 7369) OR (col1 = 6 AND col3 = 7698);
++-----------------------------------------------------------------------------------------------------+
+| QUERY PLAN                                                                                          |
++-----------------------------------------------------------------------------------------------------+
+| Project (cost=1000.00 outcnt=1000.00 selectivity=1.0000)                                            |
+|   Output: t1.col1, t1.col2, t1.col3                                                                 |
+|   ->  Table Scan on db2.t1 (cost=1000.00 outcnt=1000.00 selectivity=1.0000 blockNum=1)              |
+|         Output: t1.col1, t1.col2, t1.col3                                                           |
+|         Table: 't1' (0:'col1', 1:'col2', 2:'col3')                                                  |
+|         Hit Partition: p0, p2                                                                       |
+|         Filter Cond: (((t1.col1 = 1) and (t1.col3 = 7369)) or ((t1.col1 = 6) and (t1.col3 = 7698))) |
++-----------------------------------------------------------------------------------------------------+
+7 rows in set (0.00 sec)
+
    +

    这个查询裁剪了分区 p0 和 p2，因为查询条件与这两个分区中的数据匹配。

    +

    示例 3: HASH 分区表的等值条件

    +
    CREATE TABLE employees (
+    id INT NOT NULL,
+    fname VARCHAR(30),
+    lname VARCHAR(30),
+    hired DATE NOT NULL DEFAULT '1970-01-01',
+    separated DATE NOT NULL DEFAULT '9999-12-31',
+    job_code INT,
+    store_id INT
+) PARTITION BY HASH(store_id) PARTITIONS 4;
+
+mysql> EXPLAIN SELECT * FROM employees WHERE store_id = 10;
++------------------------------------------------+
+| QUERY PLAN                                     |
++------------------------------------------------+
+| Project                                        |
+|   ->  Table Scan on db1.employees              |
+|         Hit Partition: p0                      |
+|         Filter Cond: (employees.store_id = 10) |
++------------------------------------------------+
+4 rows in set (0.00 sec)
+
    +

    在这个查询中，只有分区 p0 包含与条件 store_id = 10 匹配的数据，因此只扫描了 p0 分区。

    +

    示例 4: HASH 分区表的多条件查询

    +
    mysql> EXPLAIN SELECT * FROM employees WHERE store_id = 10 OR store_id = 15;
++---------------------------------------------------+
+| QUERY PLAN                                        |
++---------------------------------------------------+
+| Project                                           |
+|   ->  Table Scan on db1.employees                 |
+|         Hit Partition: p0, p3                     |
+|         Filter Cond: ((employees.store_id = 10) or (employees.store_id = 15)) |
++---------------------------------------------------+
+5 rows in set (0.00 sec)
+
    +

    这个查询裁剪了 p0 和 p3 分区，因为这两个分区中包含了与条件 store_id = 10 OR store_id = 15 匹配的数据。

    +

    示例 5: 不适用于分区裁剪的场景

    +
    mysql> EXPLAIN SELECT * FROM t1 WHERE col1 > 5;
++------------------------------------------------+
+| QUERY PLAN                                     |
++------------------------------------------------+
+| Project                                        |
+|   ->  Table Scan on db1.t1                     |
+|         Hit Partition: all partitions          |
+|         Filter Cond: (t1.col1 > 5)             |
+|         Block Filter Cond: (t1.col1 > 5)       |
++------------------------------------------------+
+5 rows in set (0.00 sec)
+
    +

    在这个查询中，条件 col1 > 5 无法确定对应的分区，因此无法使用分区裁剪。

    +

    限制

    +

    MatrixOne 的分区表支持四种分区形式：Key、Hash、Range、List：

    +
      +
    • +

      但仅支持对 Key 和 Hash 两种分区表进行分区裁剪，其他分区表的裁剪将在后续逐步实现。

      +
      • +
    • +

      List 分区和 Rang 分区暂对查询性能无加速作用。

    CREATE STAGE

    +

    语法说明

    +

    CREATE STAGE 用于在 MatrixOne 数据库中创建一个命名的内部或外部数据阶段（Stage），用于数据导出，你可以创建一个数据阶段，通过将数据导出到数据阶段，你可以将数据文件下载到本地或将其存储在云存储服务中。

    +
      +
    • +

      内部阶段（Internal Stage）：内部阶段将数据文件存储在 MatrixOne 内部。内部阶段可以是永久性的或临时性的。

      +
      • +
    • +

      外部阶段（External Stage）：外部阶段引用存储在 MatrixOne 之外位置的数据文件。目前，支持以下云存储服务：

      +
        +
      • Amazon S3 存储桶
        • +
      • Aliyun 存储桶
        • +
      +
      • +
    +

    存储位置可以是私有/受保护的，也可以是公开的。但是，无法访问需要恢复才能检索的存档云存储类别中的数据。

    +

    内部或外部阶段可以包括一个目录表。目录表在云存储中存储分阶段文件的目录。

    +
      +
    • +

      配置一个指定路径，控制用户 SELECT INTO 的写入权限，在创建之后，用户只能写入指定的 STAGE 路径

      +
      • +
    • +

      如果不创建 STAGE 或全部 STAGE 都在 DISABLED 状态下，用户可以在操作系统或对象存储的权限允许情况下，写入任何路径。

      +
      • +
    • +

      如果不使用 STAGE，用户 SELECT INTO 时必须强行加入 credential 信息。

      +
      • +
    +
    +

    Note

    +
      +
    1. 集群管理员（即 root 用户）和租户管理员可以创建数据阶段。
      2. +
    2. 创建完成数据阶段以后，数据表只能导入至 STAGE 指定路径。
      3. +
    +
    +

    语法结构

    +
    > CREATE STAGE [ IF NOT EXISTS ] { stage_name }
+   { StageParams }
+   [ directoryTableParams ]
+   [ COMMENT = '<string_literal>' ]
+
+StageParams (for Amazon S3) :
+URL =  "endpoint"='<string>' CREDENTIALS = {"access_key_id"='<string>', "secret_access_key"='<string>', "filepath"='<string>', "region"='<string>'}

+ENABLE = { TRUE | FALSE }
+
    +

    语法解释

    +
      +
    • +

      IF NOT EXISTS：可选参数，用于在创建 Stage 时检查是否已存在同名的 Stage，避免重复创建。

      +
      • +
    • +

      stage_name：要创建的 Stage 的名称。

      +
      • +
    • +

      StageParams：这是一个参数组，用于指定 Stage 的配置参数。

      +
        +
      • +

        endpoint：Stage 的连接 URL，指定对象存储服务的位置。对于不同的对象存储服务（如 Amazon S3、Aliyun OSS、文件系统等），这个 URL 的内容可能有所不同。例如：s3.us-west-2.amazonaws.com

        +
        • +
      • +

        CREDENTIALS：这是一个 JSON 对象，包含连接到对象存储服务所需的凭证信息，

        +
          +
        • access_key_id：用于身份验证的访问密钥 ID。
          • +
        • secret_access_key：与访问密钥 ID 相关联的密钥。
          • +
        • "filepath"='<string>：指定 S3 存储中的文件路径或目录。
          • +
        • "region"='<string>'：指定 Amazon S3 存储所在的 AWS 区域。
          • +
        +
        • +
      +
      • +
    • +

      directoryTableParams：这是一个参数组，用于指定 Stage 的目录表（directory table）的配置。

      +
        +
      • ENABLE：是否启用目录表，值为 TRUE 或 FALSE。
        • +
      +
      • +
    +

    示例

    +
    CREATE TABLE `user` (`id` int(11) ,`user_name` varchar(255) ,`sex` varchar(255));
+INSERT INTO user(id,user_name,sex) values('1', 'weder', 'man'), ('2', 'tom', 'man'), ('3', 'wederTom', 'man');
+
+-- 创建内部数据阶段
+mysql> CREATE STAGE stage1 URL='/tmp' ENABLE = TRUE;
+
+-- 将数据从表导出到数据阶段
+mysql> SELECT * FROM user INTO OUTFILE 'stage1:/user.csv';

    If you specify an ON DUPLICATE KEY UPDATE clause and a row to be inserted would cause a duplicate value in a UNIQUE index or PRIMARY KEY, an UPDATE of the old row occurs.

    INSERT\n    [INTO] tbl_name\n    [(col_name [, col_name] ...)]\n    { {VALUES | VALUE} (value_list) [, (value_list)] ... }\n    [AS row_alias[(col_alias [, col_alias] ...)]]\n    [ON DUPLICATE KEY UPDATE assignment_list]\n\nassignment:\n    col_name = \n          value\n        | [row_alias.]col_name\n        | [tbl_name.]col_name\n        | [row_alias.]col_alias\n\nassignment_list:\n    assignment [, assignment] ...\n

    For example, if column a is declared as UNIQUE and contains the value 1, the following two statements have similar effect:

    INSERT INTO t1 (a,b,c) VALUES (1,2,3)\n  ON DUPLICATE KEY UPDATE c=c+1;\n\nUPDATE t1 SET c=c+1 WHERE a=1;\n

    If column b is also unique, the INSERT is equivalent to this UPDATE statement instead:

    UPDATE t1 SET c=c+1 WHERE a=1 OR b=2 LIMIT 1;\n

    In assignment value expressions in the ON DUPLICATE KEY UPDATE clause, you can use the VALUES(col_name) function to refer to column values from the INSERT portion of the INSERT ... ON DUPLICATE KEY UPDATE statement. In other words, VALUES(col_name) in the ON DUPLICATE KEY UPDATE clause refers to the value of col_name that would be inserted, had no duplicate-key conflict occurred. This function is especially useful in multiple-row inserts. The VALUES() function is meaningful only in the ON DUPLICATE KEY UPDATE clause or INSERT statements and returns NULL otherwise. Example:

    INSERT INTO t1 (a,b,c) VALUES (1,2,3),(4,5,6)\n  ON DUPLICATE KEY UPDATE c=VALUES(a)+VALUES(b);\n

    That statement is identical to the following two statements:

    INSERT INTO t1 (a,b,c) VALUES (1,2,3)\n  ON DUPLICATE KEY UPDATE c=3;\nINSERT INTO t1 (a,b,c) VALUES (4,5,6)\n  ON DUPLICATE KEY UPDATE c=9;\n

    If the result of INSERT ... ON DUPLICATE KEY UPDATE is incorrect such as the following example, there should be notified error messages to users and this statement failed.

    INSERT INTO t1 (a,b,c) VALUES (1,2,3)\n  ON DUPLICATE KEY UPDATE c='a';\n
    "},{"location":"MatrixOne/parser_camp_event/#2-replace-statement","title":"2. REPLACE Statement","text":"

    REPLACE works exactly like INSERT, except that if an old row in the table has the same value as a new row for a PRIMARY KEY or a UNIQUE index, the old row is deleted before the new row is inserted.

    REPLACE \n    INTO tbl_name\n    [(col_name [, col_name] ...)]\n    { {VALUES | VALUE} (value_list) [, (value_list)] ...\n      |\n      VALUES row_constructor_list\n    }\n

    Example:

    CREATE TABLE test (\n  id INT UNSIGNED NOT NULL AUTO_INCREMENT,\n  data VARCHAR(64) DEFAULT NULL,\n  ts TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,\n  PRIMARY KEY (id)\n);\n

    When we create this table and run the statements shown in the mysql client, the result is as follows:

    mysql> REPLACE INTO test VALUES (1, 'Old', '2014-08-20 18:47:00');\nQuery OK, 1 row affected (0.04 sec)\n\nmysql> REPLACE INTO test VALUES (1, 'New', '2014-08-20 18:47:42');\nQuery OK, 2 rows affected (0.04 sec)\n\nmysql> SELECT * FROM test;\n+----+------+---------------------+\n| id | data | ts                  |\n+----+------+---------------------+\n|  1 | New  | 2014-08-20 18:47:42 |\n+----+------+---------------------+\n1 row in set (0.00 sec)\n

    Now we create a second table almost identical to the first, except that the primary key now covers 2 columns, as shown here (emphasized text):

    CREATE TABLE test2 (\n  id INT UNSIGNED NOT NULL AUTO_INCREMENT,\n  data VARCHAR(64) DEFAULT NULL,\n  ts TIMESTAMP NOT NULL,\n  PRIMARY KEY (id, ts)\n);\n

    When we run on test2 the same two REPLACE statements as we did on the original test table, we obtain a different result:

    mysql> REPLACE INTO test2 VALUES (1, 'Old', '2014-08-20 18:47:00');\nQuery OK, 1 row affected (0.05 sec)\n\nmysql> REPLACE INTO test2 VALUES (1, 'New', '2014-08-20 18:47:42');\nQuery OK, 1 row affected (0.06 sec)\n\nmysql> SELECT * FROM test2;\n+----+------+---------------------+\n| id | data | ts                  |\n+----+------+---------------------+\n|  1 | Old  | 2014-08-20 18:47:00 |\n|  1 | New  | 2014-08-20 18:47:42 |\n+----+------+---------------------+\n2 rows in set (0.00 sec)\n
    "},{"location":"MatrixOne/parser_camp_event/#3-values-statement","title":"3. VALUES STATEMENT","text":"

    VALUES is a DML statement which returns a set of one or more rows as a table. In other words, it is a table value constructor which also functions as a standalone SQL statement.

    VALUES row_constructor_list [ORDER BY column_designator] [LIMIT number]\n\nrow_constructor_list:\n    ROW(value_list)[, ROW(value_list)][, ...]\n\nvalue_list:\n    value[, value][, ...]\n\ncolumn_designator:\n    column_index\n

    The VALUES statement consists of the VALUES keyword followed by a list of one or more row constructors, separated by commas. A row constructor consists of the ROW() row constructor clause with a value list of one or more scalar values enclosed in the parentheses. A value can be a literal of any MatrixOne data type or an expression that resolves to a scalar value. ROW() cannot be empty (but each of the supplied scalar values can be NULL). Each ROW() in the same VALUES statement must have the same number of values in its value list. The DEFAULT keyword is not supported by VALUES and causes a syntax error, except when it is used to supply values in an INSERT statement. The output of VALUES is a table:

    mysql> VALUES ROW(1,-2,3), ROW(5,7,9), ROW(4,6,8);\n+----------+----------+----------+\n| column_0 | column_1 | column_2 |\n+----------+----------+----------+\n|        1 |       -2 |        3 |\n|        5 |        7 |        9 |\n|        4 |        6 |        8 |\n+----------+----------+----------+\n3 rows in set (0.00 sec)\n

    The columns of the table output from VALUES have the implicitly named columns column_0, column_1, column_2, and so on, always beginning with 0. This fact can be used to order the rows by column using an optional ORDER BY clause in the same way that this clause works with a SELECT statement, as shown here:

    mysql> VALUES ROW(1,-2,3), ROW(5,7,9), ROW(4,6,8) ORDER BY column_1;\n+----------+----------+----------+\n| column_0 | column_1 | column_2 |\n+----------+----------+----------+\n|        1 |       -2 |        3 |\n|        4 |        6 |        8 |\n|        5 |        7 |        9 |\n+----------+----------+----------+\n3 rows in set (0.00 sec)\n\nmysql> VALUES ROW(1,-2,3), ROW(5,7,9), ROW(4,6,8) ORDER BY column_1 limit 1;\n+----------+----------+----------+\n| column_0 | column_1 | column_2 |\n+----------+----------+----------+\n|        1 |       -2 |        3 |\n+----------+----------+----------+\n1 row in set (0.00 sec)\n

    The VALUES statement is permissive regarding data types of column values; you can mix types within the same column, as shown here:

    mysql> VALUES ROW(\"q\", 42, '2019-12-18'),\n    ->     ROW(23, \"abc\", 98.6),\n    ->     ROW(27.0002, \"Mary Smith\", '{\"a\": 10, \"b\": 25}');\n+----------+------------+--------------------+\n| column_0 | column_1   | column_2           |\n+----------+------------+--------------------+\n| q        | 42         | 2019-12-18         |\n| 23       | abc        | 98.6               |\n| 27.0002  | Mary Smith | {\"a\": 10, \"b\": 25} |\n+----------+------------+--------------------+\n3 rows in set (0.00 sec)\n

    With UNION, as shown here:

    mysql> VALUES ROW(1,2), ROW(3,4), ROW(5,6)\n     >     UNION VALUES ROW(10,15),ROW(20,25);\n+----------+----------+\n| column_0 | column_1 |\n+----------+----------+\n|        1 |        2 |\n|        3 |        4 |\n|        5 |        6 |\n|       10 |       15 |\n|       20 |       25 |\n+----------+----------+\n5 rows in set (0.00 sec)\n

    DO executes the expressions but does not return any results. In most respects, DO is shorthand for SELECT expr, ..., but has the advantage that it is slightly faster when you do not care about the result.

    DO expr [, expr] ...\n

    DO is useful primarily with functions that have side effects, such as RELEASE_LOCK(). Example: This SELECT statement pauses, but also produces a result set:

    mysql> SELECT SLEEP(5);\n+----------+\n| SLEEP(5) |\n+----------+\n|        0 |\n+----------+\n1 row in set (5.02 sec)\n

    DO, on the other hand, pauses without producing a result set.

    mysql> DO SLEEP(5);\nQuery OK, 0 rows affected (4.99 sec)\n

    DECLARE statement declares local variables within stored programs. To provide a default value for a variable, include a DEFAULT clause. The value can be specified as an expression; it need not be a constant. If the DEFAULT clause is missing, the initial value is NULL.

    The HANDLER ... OPEN statement opens a table, making it accessible using subsequent HANDLER ... READ statements. This table object is not shared by other sessions and is not closed until the session calls HANDLER ... CLOSE or the session terminates. The HANDLER ... READ syntax fetches a row from the table in natural row order that matches the WHERE condition. Natural row order is the order in which rows are stored in a TAE table data file. Without a LIMIT clause, all forms of HANDLER ... READ fetch a single row if one is available. To return a specific number of rows, include a LIMIT clause.

    This statement creates a new trigger. A trigger is a named database object that is associated with a table, and that activates when a particular event occurs for the table. The trigger becomes associated with the table named tbl_name, which must refer to a permanent table.

    IF NOT EXISTS prevents an error from occurring if a trigger having the same name, on the same table, exists in the same schema.

    trigger_time is the trigger action time. It can be BEFORE or AFTER to indicate that the trigger activates before or after each row to be modified.

    trigger_event indicates the kind of operation that activates the trigger. These trigger_event values are permitted: INSERT: The trigger activates whenever a new row is inserted into the table (for example, through INSERT, LOAD DATA, and REPLACE statements). UPDATE: The trigger activates whenever a row is modified (for example, through UPDATE statements). DELETE: The trigger activates whenever a row is deleted from the table (for example, through DELETE and REPLACE statements). DROP TABLE and TRUNCATE TABLE statements on the table do not activate this trigger, because they do not use DELETE. Dropping a partition does not activate DELETE triggers, either. The trigger_event does not represent a literal type of SQL statement that activates the trigger so much as it represents a type of table operation. For example, an INSERT trigger activates not only for INSERT statements but also LOAD DATA statements because both statements insert rows into a table. trigger_body is the statement to execute when the trigger activates. To execute multiple statements, use the BEGIN ... END compound statement construct.

    DROP TRIGGER [IF EXISTS] [schema_name.]trigger_name\n

    This statement drops a trigger. The schema (database) name is optional. If the schema is omitted, the trigger is dropped from the default schema.

See the config documentation for more details\nlistener.security.protocol.map=CONTROLLER:PLAINTEXT,PLAINTEXT:PLAINTEXT,SSL:SSL,SASL_PLAINTEXT:SASL_PLAINTEXT,SASL_SSL:SASL_SSL\n\n# The number of threads that the server uses for receiving requests from the network and sending responses to the network\nnum.network.threads=3\n\n# The number of threads that the server uses for processing requests, which may include disk I/O\nnum.io.threads=8\n\n# The send buffer (SO_SNDBUF) used by the socket server\nsocket.send.buffer.bytes=102400\n\n# The receive buffer (SO_RCVBUF) used by the socket server\nsocket.receive.buffer.bytes=102400\n\n# The maximum size of a request that the socket server will accept (protection against OOM)\nsocket.request.max.bytes=104857600\n\n\n############################# Log Basics #############################\n\n# A comma separated list of directories under which to store log files\nlog.dirs=/home/software/kafka_2.13-3.5.0/kraft-combined-logs\n\n# The default number of log partitions per topic. More partitions allow greater\n# parallelism for consumption, but this will also result in more files across\n# the brokers.\nnum.partitions=1\n\n# The number of threads per data directory to be used for log recovery at startup and flushing at shutdown.\n# This value is recommended to be increased for installations with data dirs located in RAID array.\nnum.recovery.threads.per.data.dir=1\n\n############################# Internal Topic Settings  #############################\n# The replication factor for the group metadata internal topics \"__consumer_offsets\" and \"__transaction_state\"\n# For anything other than development testing, a value greater than 1 is recommended to ensure availability such as 3.\noffsets.topic.replication.factor=1\ntransaction.state.log.replication.factor=1\ntransaction.state.log.min.isr=1\n\n############################# Log Flush Policy #############################\n\n# Messages are immediately written to the filesystem but by default we only fsync() to sync\n# the OS cache lazily. The following configurations control the flush of data to disk.\n# There are a few important trade-offs here:\n#    1. Durability: Unflushed data may be lost if you are not using replication.\n#    2. Latency: Very large flush intervals may lead to latency spikes when the flush does occur as there will be a lot of data to flush.\n#    3. Throughput: The flush is generally the most expensive operation, and a small flush interval may lead to excessive seeks.\n# The settings below allow one to configure the flush policy to flush data after a period of time or\n# every N messages (or both). This can be done globally and overridden on a per-topic basis.\n\n# The number of messages to accept before forcing a flush of data to disk\n#log.flush.interval.messages=10000\n\n# The maximum amount of time a message can sit in a log before we force a flush\n#log.flush.interval.ms=1000\n\n############################# Log Retention Policy #############################\n\n# The following configurations control the disposal of log segments. The policy can\n# be set to delete segments after a period of time, or after a given size has accumulated.\n# A segment will be deleted whenever *either* of these criteria are met. Deletion always happens\n# from the end of the log.\n\n# The minimum age of a log file to be eligible for deletion due to age\nlog.retention.hours=72\n\n# A size-based retention policy for logs. Segments are pruned from the log unless the remaining\n# segments drop below log.retention.bytes. Functions independently of log.retention.hours.\n#log.retention.bytes=1073741824\n\n# The maximum size of a log segment file. When this size is reached a new log segment will be created.\nlog.segment.bytes=1073741824\n\n# The interval at which log segments are checked to see if they can be deleted according\n# to the retention policies\nlog.retention.check.interval.ms=300000\n

      If you specify an ON DUPLICATE KEY UPDATE clause and a row to be inserted would cause a duplicate value in a UNIQUE index or PRIMARY KEY, an UPDATE of the old row occurs.

      INSERT\n    [INTO] tbl_name\n    [(col_name [, col_name] ...)]\n    { {VALUES | VALUE} (value_list) [, (value_list)] ... }\n    [AS row_alias[(col_alias [, col_alias] ...)]]\n    [ON DUPLICATE KEY UPDATE assignment_list]\n\nassignment:\n    col_name = \n          value\n        | [row_alias.]col_name\n        | [tbl_name.]col_name\n        | [row_alias.]col_alias\n\nassignment_list:\n    assignment [, assignment] ...\n

      For example, if column a is declared as UNIQUE and contains the value 1, the following two statements have similar effect:

      INSERT INTO t1 (a,b,c) VALUES (1,2,3)\n  ON DUPLICATE KEY UPDATE c=c+1;\n\nUPDATE t1 SET c=c+1 WHERE a=1;\n

      If column b is also unique, the INSERT is equivalent to this UPDATE statement instead:

      UPDATE t1 SET c=c+1 WHERE a=1 OR b=2 LIMIT 1;\n

      In assignment value expressions in the ON DUPLICATE KEY UPDATE clause, you can use the VALUES(col_name) function to refer to column values from the INSERT portion of the INSERT ... ON DUPLICATE KEY UPDATE statement. In other words, VALUES(col_name) in the ON DUPLICATE KEY UPDATE clause refers to the value of col_name that would be inserted, had no duplicate-key conflict occurred. This function is especially useful in multiple-row inserts. The VALUES() function is meaningful only in the ON DUPLICATE KEY UPDATE clause or INSERT statements and returns NULL otherwise. Example:

      INSERT INTO t1 (a,b,c) VALUES (1,2,3),(4,5,6)\n  ON DUPLICATE KEY UPDATE c=VALUES(a)+VALUES(b);\n

      That statement is identical to the following two statements:

      INSERT INTO t1 (a,b,c) VALUES (1,2,3)\n  ON DUPLICATE KEY UPDATE c=3;\nINSERT INTO t1 (a,b,c) VALUES (4,5,6)\n  ON DUPLICATE KEY UPDATE c=9;\n

      If the result of INSERT ... ON DUPLICATE KEY UPDATE is incorrect such as the following example, there should be notified error messages to users and this statement failed.

      INSERT INTO t1 (a,b,c) VALUES (1,2,3)\n  ON DUPLICATE KEY UPDATE c='a';\n
      "},{"location":"MatrixOne/parser_camp_event/#2-replace-statement","title":"2. REPLACE Statement","text":"

      REPLACE works exactly like INSERT, except that if an old row in the table has the same value as a new row for a PRIMARY KEY or a UNIQUE index, the old row is deleted before the new row is inserted.

      REPLACE \n    INTO tbl_name\n    [(col_name [, col_name] ...)]\n    { {VALUES | VALUE} (value_list) [, (value_list)] ...\n      |\n      VALUES row_constructor_list\n    }\n

      Example:

      CREATE TABLE test (\n  id INT UNSIGNED NOT NULL AUTO_INCREMENT,\n  data VARCHAR(64) DEFAULT NULL,\n  ts TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,\n  PRIMARY KEY (id)\n);\n

      When we create this table and run the statements shown in the mysql client, the result is as follows:

      mysql> REPLACE INTO test VALUES (1, 'Old', '2014-08-20 18:47:00');\nQuery OK, 1 row affected (0.04 sec)\n\nmysql> REPLACE INTO test VALUES (1, 'New', '2014-08-20 18:47:42');\nQuery OK, 2 rows affected (0.04 sec)\n\nmysql> SELECT * FROM test;\n+----+------+---------------------+\n| id | data | ts                  |\n+----+------+---------------------+\n|  1 | New  | 2014-08-20 18:47:42 |\n+----+------+---------------------+\n1 row in set (0.00 sec)\n

      Now we create a second table almost identical to the first, except that the primary key now covers 2 columns, as shown here (emphasized text):

      CREATE TABLE test2 (\n  id INT UNSIGNED NOT NULL AUTO_INCREMENT,\n  data VARCHAR(64) DEFAULT NULL,\n  ts TIMESTAMP NOT NULL,\n  PRIMARY KEY (id, ts)\n);\n

      When we run on test2 the same two REPLACE statements as we did on the original test table, we obtain a different result:

      mysql> REPLACE INTO test2 VALUES (1, 'Old', '2014-08-20 18:47:00');\nQuery OK, 1 row affected (0.05 sec)\n\nmysql> REPLACE INTO test2 VALUES (1, 'New', '2014-08-20 18:47:42');\nQuery OK, 1 row affected (0.06 sec)\n\nmysql> SELECT * FROM test2;\n+----+------+---------------------+\n| id | data | ts                  |\n+----+------+---------------------+\n|  1 | Old  | 2014-08-20 18:47:00 |\n|  1 | New  | 2014-08-20 18:47:42 |\n+----+------+---------------------+\n2 rows in set (0.00 sec)\n
      "},{"location":"MatrixOne/parser_camp_event/#3-values-statement","title":"3. VALUES STATEMENT","text":"

      VALUES is a DML statement which returns a set of one or more rows as a table. In other words, it is a table value constructor which also functions as a standalone SQL statement.

      VALUES row_constructor_list [ORDER BY column_designator] [LIMIT number]\n\nrow_constructor_list:\n    ROW(value_list)[, ROW(value_list)][, ...]\n\nvalue_list:\n    value[, value][, ...]\n\ncolumn_designator:\n    column_index\n

      The VALUES statement consists of the VALUES keyword followed by a list of one or more row constructors, separated by commas. A row constructor consists of the ROW() row constructor clause with a value list of one or more scalar values enclosed in the parentheses. A value can be a literal of any MatrixOne data type or an expression that resolves to a scalar value. ROW() cannot be empty (but each of the supplied scalar values can be NULL). Each ROW() in the same VALUES statement must have the same number of values in its value list. The DEFAULT keyword is not supported by VALUES and causes a syntax error, except when it is used to supply values in an INSERT statement. The output of VALUES is a table:

      mysql> VALUES ROW(1,-2,3), ROW(5,7,9), ROW(4,6,8);\n+----------+----------+----------+\n| column_0 | column_1 | column_2 |\n+----------+----------+----------+\n|        1 |       -2 |        3 |\n|        5 |        7 |        9 |\n|        4 |        6 |        8 |\n+----------+----------+----------+\n3 rows in set (0.00 sec)\n

      The columns of the table output from VALUES have the implicitly named columns column_0, column_1, column_2, and so on, always beginning with 0. This fact can be used to order the rows by column using an optional ORDER BY clause in the same way that this clause works with a SELECT statement, as shown here:

      mysql> VALUES ROW(1,-2,3), ROW(5,7,9), ROW(4,6,8) ORDER BY column_1;\n+----------+----------+----------+\n| column_0 | column_1 | column_2 |\n+----------+----------+----------+\n|        1 |       -2 |        3 |\n|        4 |        6 |        8 |\n|        5 |        7 |        9 |\n+----------+----------+----------+\n3 rows in set (0.00 sec)\n\nmysql> VALUES ROW(1,-2,3), ROW(5,7,9), ROW(4,6,8) ORDER BY column_1 limit 1;\n+----------+----------+----------+\n| column_0 | column_1 | column_2 |\n+----------+----------+----------+\n|        1 |       -2 |        3 |\n+----------+----------+----------+\n1 row in set (0.00 sec)\n

      The VALUES statement is permissive regarding data types of column values; you can mix types within the same column, as shown here:

      mysql> VALUES ROW(\"q\", 42, '2019-12-18'),\n    ->     ROW(23, \"abc\", 98.6),\n    ->     ROW(27.0002, \"Mary Smith\", '{\"a\": 10, \"b\": 25}');\n+----------+------------+--------------------+\n| column_0 | column_1   | column_2           |\n+----------+------------+--------------------+\n| q        | 42         | 2019-12-18         |\n| 23       | abc        | 98.6               |\n| 27.0002  | Mary Smith | {\"a\": 10, \"b\": 25} |\n+----------+------------+--------------------+\n3 rows in set (0.00 sec)\n

      With UNION, as shown here:

      mysql> VALUES ROW(1,2), ROW(3,4), ROW(5,6)\n     >     UNION VALUES ROW(10,15),ROW(20,25);\n+----------+----------+\n| column_0 | column_1 |\n+----------+----------+\n|        1 |        2 |\n|        3 |        4 |\n|        5 |        6 |\n|       10 |       15 |\n|       20 |       25 |\n+----------+----------+\n5 rows in set (0.00 sec)\n

      DO executes the expressions but does not return any results. In most respects, DO is shorthand for SELECT expr, ..., but has the advantage that it is slightly faster when you do not care about the result.

      DO expr [, expr] ...\n

      DO is useful primarily with functions that have side effects, such as RELEASE_LOCK(). Example: This SELECT statement pauses, but also produces a result set:

      DECLARE statement declares local variables within stored programs. To provide a default value for a variable, include a DEFAULT clause. The value can be specified as an expression; it need not be a constant. If the DEFAULT clause is missing, the initial value is NULL.

      The HANDLER ... OPEN statement opens a table, making it accessible using subsequent HANDLER ... READ statements. This table object is not shared by other sessions and is not closed until the session calls HANDLER ... CLOSE or the session terminates. The HANDLER ... READ syntax fetches a row from the table in natural row order that matches the WHERE condition. Natural row order is the order in which rows are stored in a TAE table data file.

      IF NOT EXISTS prevents an error from occurring if a trigger having the same name, on the same table, exists in the same schema.

      trigger_time is the trigger action time. It can be BEFORE or AFTER to indicate that the trigger activates before or after each row to be modified.

      trigger_event indicates the kind of operation that activates the trigger. These trigger_event values are permitted: INSERT: The trigger activates whenever a new row is inserted into the table (for example, through INSERT, LOAD DATA, and REPLACE statements). UPDATE: The trigger activates whenever a row is modified (for example, through UPDATE statements). DELETE: The trigger activates whenever a row is deleted from the table (for example, through DELETE and REPLACE statements). DROP TABLE and TRUNCATE TABLE statements on the table do not activate this trigger, because they do not use DELETE. Dropping a partition does not activate DELETE triggers, either. The trigger_event does not represent a literal type of SQL statement that activates the trigger so much as it represents a type of table operation. For example, an INSERT trigger activates not only for INSERT statements but also LOAD DATA statements because both statements insert rows into a table. trigger_body is the statement to execute when the trigger activates. To execute multiple statements, use the BEGIN ... END compound statement construct.

      DROP TRIGGER [IF EXISTS] [schema_name.]trigger_name\n

See the config documentation for more details\nlistener.security.protocol.map=CONTROLLER:PLAINTEXT,PLAINTEXT:PLAINTEXT,SSL:SSL,SASL_PLAINTEXT:SASL_PLAINTEXT,SASL_SSL:SASL_SSL\n\n# The number of threads that the server uses for receiving requests from the network and sending responses to the network\nnum.network.threads=3\n\n# The number of threads that the server uses for processing requests, which may include disk I/O\nnum.io.threads=8\n\n# The send buffer (SO_SNDBUF) used by the socket server\nsocket.send.buffer.bytes=102400\n\n# The receive buffer (SO_RCVBUF) used by the socket server\nsocket.receive.buffer.bytes=102400\n\n# The maximum size of a request that the socket server will accept (protection against OOM)\nsocket.request.max.bytes=104857600\n\n\n############################# Log Basics #############################\n\n# A comma separated list of directories under which to store log files\nlog.dirs=/home/software/kafka_2.13-3.5.0/kraft-combined-logs\n\n# The default number of log partitions per topic. More partitions allow greater\n# parallelism for consumption, but this will also result in more files across\n# the brokers.\nnum.partitions=1\n\n# The number of threads per data directory to be used for log recovery at startup and flushing at shutdown.\n# This value is recommended to be increased for installations with data dirs located in RAID array.\nnum.recovery.threads.per.data.dir=1\n\n############################# Internal Topic Settings  #############################\n# The replication factor for the group metadata internal topics \"__consumer_offsets\" and \"__transaction_state\"\n# For anything other than development testing, a value greater than 1 is recommended to ensure availability such as 3.\noffsets.topic.replication.factor=1\ntransaction.state.log.replication.factor=1\ntransaction.state.log.min.isr=1\n\n############################# Log Flush Policy #############################\n\n# Messages are immediately written to the filesystem but by default we only fsync() to sync\n# the OS cache lazily. The following configurations control the flush of data to disk.\n# There are a few important trade-offs here:\n#    1. Durability: Unflushed data may be lost if you are not using replication.\n#    2. Latency: Very large flush intervals may lead to latency spikes when the flush does occur as there will be a lot of data to flush.\n#    3. Throughput: The flush is generally the most expensive operation, and a small flush interval may lead to excessive seeks.\n# The settings below allow one to configure the flush policy to flush data after a period of time or\n# every N messages (or both). This can be done globally and overridden on a per-topic basis.\n\n# The number of messages to accept before forcing a flush of data to disk\n#log.flush.interval.messages=10000\n\n# The maximum amount of time a message can sit in a log before we force a flush\n#log.flush.interval.ms=1000\n\n############################# Log Retention Policy #############################\n\n# The following configurations control the disposal of log segments. The policy can\n# be set to delete segments after a period of time, or after a given size has accumulated.\n# A segment will be deleted whenever *either* of these criteria are met. Deletion always happens\n# from the end of the log.\n\n# The minimum age of a log file to be eligible for deletion due to age\nlog.retention.hours=72\n\n# A size-based retention policy for logs. Segments are pruned from the log unless the remaining\n# segments drop below log.retention.bytes. Functions independently of log.retention.hours.\n#log.retention.bytes=1073741824\n\n# The maximum size of a log segment file. When this size is reached a new log segment will be created.\nlog.segment.bytes=1073741824\n\n# The interval at which log segments are checked to see if they can be deleted according\n# to the retention policies\nlog.retention.check.interval.ms=300000\n
