学习MySQL的分布式计算和分析技巧有哪些？

-- 创建数据表
CREATE TABLE user (
    id INT AUTO_INCREMENT PRIMARY KEY,
    name VARCHAR(50) NOT NULL,
    age INT NOT NULL
) ENGINE=InnoDB;

-- 创建分片表
CREATE TABLE user_1 (
    id INT AUTO_INCREMENT PRIMARY KEY,
    name VARCHAR(50) NOT NULL,
    age INT NOT NULL
) ENGINE=InnoDB;

CREATE TABLE user_2 (
    id INT AUTO_INCREMENT PRIMARY KEY,
    name VARCHAR(50) NOT NULL,
    age INT NOT NULL
) ENGINE=InnoDB;

-- 创建分片规则
CREATE TABLE shard_rule (
    shard_id INT PRIMARY KEY,
    min_value INT,
    max_value INT
) ENGINE=InnoDB;

INSERT INTO shard_rule (shard_id, min_value, max_value) VALUES (1, 0, 50);
INSERT INTO shard_rule (shard_id, min_value, max_value) VALUES (2, 51, 100);

-- 插入数据
INSERT INTO user (name, age) VALUES ('张三', 18);
INSERT INTO user (name, age) VALUES ('李四', 20);

-- 查询数据
SELECT * FROM user_1;
SELECT * FROM user_2;

-- 设置并行度
SET max_execution_threads = 4;

-- 执行并行查询
SELECT COUNT(*) FROM table1;
SELECT COUNT(*) FROM table2;
SELECT COUNT(*) FROM table3;
SELECT COUNT(*) FROM table4;

-- 创建连接
CREATE CONNECTION remote_conn 
URL 'jdbc:mysql://192.168.1.100:3306/db'
USER 'user' 
PASSWORD 'password';

-- 执行分布式查询
SELECT * FROM table1@remote_conn;
SELECT * FROM table2@remote_conn;
SELECT * FROM table3@remote_conn;
SELECT * FROM table4@remote_conn;
