一、环境
- jdk8
- flink 1.16.1（部署在远程服务器：192.168.137.99）
- Flink CDC 2.3.0
- MySQL 8.0（安装在本地：192.168.3.31）
（安装部署过程略）
二、准备
准备三个数据库：flink_source、flink_sink、flink_sink_second。
将flink_source.source_test表实时同步到flink_sink和flink_sink_second的sink_test表。
（建库建表过程略）
三、Flink SQL Client上开发SQL作业
开发过程可以参考Flink CDC官网的例子（譬如：基于 Flink CDC 构建 MySQL 和 Postgres 的 Streaming ETL）。
这里介绍的是MySQL到MySQL的同步，稍有不同，需要下载JDBC SQL连接器的依赖包（下载地址，使用方法），放到目录 {flink-1.16.1}/lib/ 下，用于使用JDBC SQL连接器连接MySQL的sink库。
✳注意下面两个jar的区别，是需要将flink-sql-connector-mysql-cdc-2.3.0.jar放到{flink-1.16.1}/lib/ 下。由于网络限制，本人最初是通过maven下载的flink-connector-mysql-cdc-2.3.0.jar，导致了各种找不到类的异常。
flink-sql-connector-mysql-cdc-2.3.0.jar（包含有依赖的jar）
flink-connector-mysql-cdc-2.3.0.jar（不包含依赖jar）
flink-sql-connector-mysql-cdc-2.3.0.jar：
<dependency>
<groupId>***.ververica</groupId>
<artifactId>flink-sql-connector-mysql-cdc</artifactId>
<version>2.3.0</version>
</dependency>
flink-connector-mysql-cdc-2.3.0.jar：
<dependency>
<groupId>***.ververica</groupId>
<artifactId>flink-connector-mysql-cdc</artifactId>
<version>2.3.0</version>
</dependency>
使用下面的命令启动 Flink SQL CLI
./bin/sql-client.sh
然后使用下面的建表语句创建Flink表，以及将flink_source.source_test表实时同步到flink_sink、flink_sink_second的sink_test表。
Flink SQL> SET execution.checkpointing.interval = 3s;

访问Flink web：http://192.168.137.99:8081/#/job/running，可以看到已经新建了两个作业。
四、使用本机执行环境开发SQL作业
直接贴代码。

import org.apache.flink.table.api.EnvironmentSettings;
import org.apache.flink.table.api.bridge.java.StreamTableEnvironment;
public class FlinkDemo {
public static void main(String[] args) throws Exception {
StreamExecutionEnvironment env = null;
// 本机执行环境
env = StreamExecutionEnvironment.getExecutionEnvironment();
// 远程执行环境
// env = StreamExecutionEnvironment.createRemoteEnvironment("192.168.137.99", 8081);
env.enableCheckpointing(3000l).setParallelism(2);

}
public static String sourceDDL() {
String sourceDDL = "CREATE TABLE source_test (\n" +

return sourceDDL;

" 'table-name' = 'sink_test'\n" +
");";
return sinkDDL;
}
}
五、远程执行环境开发SQL作业
提交SQL作业到远程Flink集群上执行，需要使用下面的方法创建执行环境：
StreamExecutionEnvironment.createRemoteEnvironment("192.168.137.99", 8081);
而本机执行是：
StreamExecutionEnvironment.getExecutionEnvironment();
上面的FlinkDemo.java，修改执行环境后，运行代码提交作业：
另外在远程执行的时候，必须使用flink-sql-connector-mysql-cdc，不能使用flink-connector-mysql-cdc。否则会报错：Caused by: java.io.StreamCorruptedException: unexpected block data
