-Dtaskmanager.numberOfTaskSlots=2

2、集群实例管理——新建

4、dinky开发

4.1、准备数据

4.1.1、MySQL中建表

 -- MySQL
CREATE TABLE products (
  id INTEGER NOT NULL AUTO_INCREMENT PRIMARY KEY,
  name VARCHAR(255) NOT NULL,
  description VARCHAR(512)
);
ALTER TABLE products AUTO_INCREMENT = 101;

INSERT INTO products
VALUES (default,"scooter","Small 2-wheel scooter"),
       (default,"car battery","12V car battery"),
       (default,"12-pack drill bits","12-pack of drill bits with sizes ranging from #40 to #3"),
       (default,"hammer","12oz carpenter's hammer"),
       (default,"hammer","14oz carpenter's hammer"),
       (default,"hammer","16oz carpenter's hammer"),
       (default,"rocks","box of assorted rocks"),
       (default,"jacket","water resistent black wind breaker"),
       (default,"spare tire","24 inch spare tire");

CREATE TABLE orders (
  order_id INTEGER NOT NULL AUTO_INCREMENT PRIMARY KEY,
  order_date DATETIME NOT NULL,
  customer_name VARCHAR(255) NOT NULL,
  price DECIMAL(10, 5) NOT NULL,
  product_id INTEGER NOT NULL,
  order_status BOOLEAN NOT NULL -- Whether order has been placed
) AUTO_INCREMENT = 10001;

INSERT INTO orders
VALUES (default, '2020-07-30 10:08:22', 'Jark', 50.50, 102, false),
       (default, '2020-07-30 10:11:09', 'Sally', 15.00, 105, false),
       (default, '2020-07-30 12:00:30', 'Edward', 25.25, 106, false);

update gmall.orders set price=55.5 where order_id=10001;

4.2、汇总到一个 topic

-- 汇总到一个 topic
-- 当指定 sink.topic 参数时，所有 Change Log 会被写入这一个 topic。

EXECUTE CDCSOURCE cdc_kafka_one WITH (
 'connector' = 'mysql-cdc',
 'hostname' = '192.168.0.122',
 'port' = '3306',
 'username' = 'root',
 'password' = '123456',
 'checkpoint' = '3000',
 'scan.startup.mode' = 'initial',
 'parallelism' = '1',
 'table-name' = 'data\.products,data\.orders',
 'sink.connector'='datastream-kafka',
 'sink.topic'='dlinkcdc',
 'sink.brokers'='node-124:6667,node-131:6667,node-107:6667'
);

4.3、汇总到多个 topic

-- 当不指定 sink.topic 参数时，所有 Change Log 会被写入对应库表名的 topic。

EXECUTE CDCSOURCE cdc_kafka_mul WITH (
 'connector' = 'mysql-cdc',
 'hostname' = '192.168.0.122',
 'port' = '3306',
 'username' = 'root',
 'password' = '123456',
 'checkpoint' = '3000',
 'scan.startup.mode' = 'initial',
 'parallelism' = '1',
 'table-name' = 'data\.products,data\.orders',
 'sink.connector'='datastream-kafka',
 'sink.brokers'='node-124:6667,node-131:6667,node-107:6667'
);

4.4、准备数据

4.4.1、MySQL中创建表

--MySQL中创建表s_user

CREATE TABLE `s_user` (
   `id` INT(11) NOT NULL,
   `name` VARCHAR(32) DEFAULT NULL,
   `p_id` INT(2) DEFAULT NULL,
   PRIMARY KEY (`id`)
);

--插入数据：
insert into s_user values(10086,'lm',61),(10010, 'ls',11), (10000,'ll',61);

4.4.2、StarRocks中创建表

CREATE TABLE IF NOT EXISTS tmp.`s_user` (
   `id` int(10) NOT NULL COMMENT "",
   `name` varchar(20) NOT NULL COMMENT "",
   `p_id` INT(2) NULL COMMENT ""
)
PRIMARY KEY(`id`)
DISTRIBUTED BY HASH(`id`) BUCKETS 1
PROPERTIES (
"replication_num" = "1"
);

4.4.3、创建MySQL-To-StarRocks任务

--创建映射至MySQL的映射表source_mysql_suser
create table source_mysql_suser (
   id int,
   name string,
   p_id int,
   primary key (id) not enforced
)with (
   'connector' = 'jdbc',
   'url' = 'jdbc:mysql://192.168.0.122:3306/data',
   'username' = 'root',
   'password' = '123456',
   'table-name' = 's_user'
);


--创建至StarRocks的映射表sink_starrocks_suser：
CREATE TABLE sink_starrocks_suser (
   id INT,
   name STRING,
   p_id INT,
   PRIMARY KEY (id) NOT ENFORCED
)WITH (
   'connector' = 'starrocks',
   'jdbc-url'='jdbc:mysql://192.168.0.106:9030',
   'load-url'='192.168.0.106:8030',
   'database-name' = 'tmp',
   'table-name' = 's_user',
   'username' = 'starrocks',
   'password' = 'StarRocks*2023',
   'sink.buffer-flush.interval-ms' = '5000',
   'sink.properties.column_separator' = '\x01',
   'sink.properties.row_delimiter' = '\x02'
);

--清洗数据并写入StarRocks
insert into sink_starrocks_suser select id,name,p_id from source_mysql_suser where p_id = 61;
