Fink CDC数据同步(四)Mysql数据同步到Kafka

依赖项

将下列依赖包放在flink/lib

flink-sql-connector-kafka-1.16.2

创建映射表

创建mysql映射表

CREATE TABLE if not exists mysql_user (
     id     int,
     name   STRING,
     birth  STRING,
     gender    STRING,
     PRIMARY KEY (`id`) NOT ENFORCED
) WITH (
    'connector'= 'mysql-cdc',
    'hostname'= '192.168.0.1',
    'port'= '3306',
    'username'= 'user',
    'password'='password',
    'server-time-zone'= 'Asia/Shanghai',
    'debezium.snapshot.mode'='initial',
    'database-name'= 'bigdata',
    'table-name'= 'user'
); 

select * from mysql_user;

创建upsert-kafka 表

CREATE TABLE kafka_user_upsert(
     id     int,
     name   string,
     birth  string,
     gender    string,
PRIMARY KEY (`id`) NOT ENFORCED
) WITH (
 'connector' = 'upsert-kafka',
 'topic' = 'flink-cdc-user',
 'properties.bootstrap.servers' = '192.168.0.4:6668',
 'properties.group.id' = 'flink-cdc-kafka-group',
 'key.format' = 'json',
 'value.format' = 'json'
);

这里指定的Kafka topic会自动创建,也可以预先自行创建

生成作业

insert into kafka_user_upsert select * from mysql_user;

select * from kafka_user_upsert;
