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;
