flink cdc同步mysql数据

一、api

添加依赖

<dependency>
   <groupId>org.apache.flink</groupId>
   <artifactId>flink-connector-mysql-cdc</artifactId>
   <!--  请使用已发布的版本依赖，snapshot 版本的依赖需要本地自行编译。 -->
   <version>3.3-SNAPSHOT</version>
</dependency>

二、sql客户端

客户端只需要添加 flink-sql-connector-mysql-cdcjar包（注意：和api依赖的包名区分），这里面已经整合了debezium-connector-mysql模块

配置同步

CREATE TABLE mysql_cdc_source (
    order_id STRING,
    user_id STRING,
    amount DECIMAL(10,2),
    update_time TIMESTAMP(3),
    dt STRING,
    PRIMARY KEY (order_id) NOT ENFORCED
) WITH (
    'connector' = 'mysql-cdc',
    'hostname' = 'chb1',
    'port' = '3306',
    'username' = 'root',
    'password' = '123456',
    'database-name' = 'paimon_test',
    'table-name' = 'mysql_orders',
    'server-time-zone' = 'Asia/Shanghai'  -- 时区配置（避免时间偏差）
);
select * from mysql_cdc_source;
