关于Apache SeaTunnel
Apache SeaTunnel 原名 Waterdrop，在 2021 年 10 月更名为 SeaTunnel 并申请加入 Apache孵化器。目前 Apache SeaTunnel 已发布 40+个版本，并在大量企业生产实践中使用，包括 J.P.Morgan、字节跳动、Stey、中国移动、富士康、腾讯云、国双、中科大数据研究院、360、Shoppe、Bilibili、新浪、搜狗、唯品会等企业，广泛应用于海量异构数据集成、CDC 数据同步，SaaS 数据集成以及多源数据处理等场景中。
2021 年 12 月 9 日， Apache SeaTunnel 以全票通过的优秀表现正式成为 Apache 孵化器项目。
2023 年 5 月 17 日，Apache 董事会通过 Apache SeaTunnel 毕业决议，结束了为期 18 个月的孵化，正式确定 Apache SeaTunnel 成为 Apache 顶级项目
Apache SeaTunnel 是新一代高性能、分布式、海量数据集成工具，支持上百种数据源 ( Database/Cloud/SaaS ) 支持海量数据的实时 CDC 和批量同步，可以稳定高效地同步万亿级数据。
作为一款简单一易用、超高性能、支持实时流式和离线批量处理的数据集成平台，Apache SeaTunnel 整体的特征和优势包括：
- 丰富且可扩展的连接器:SeaTunnel提供了一个不依赖于特定执行引擎的连接器API。基于此API开发的连接器(Source, Transform, Sink)可以在许多不同的引擎上运行，例如当前支持的SeaTunnel Engine, Flink和Spark。
- 连接器插件:插件设计允许用户轻松开发自己的连接器并将其集成到SeaTunnel项目中。目前，SeaTunnel支持100多个连接器，而且这个数字还在飙升。下面是当前支持的连接器列表
- 批处理流集成:基于SeaTunnel Connector API开发的连接器完美兼容离线同步、实时同步、全同步、增量同步等场景。它们大大降低了管理数据集成任务的难度。
- 支持分布式快照算法，保证数据一致性。
- 多引擎支持:SeaTunnel默认使用SeaTunnel引擎进行数据同步。SeaTunnel还支持使用Flink或Spark作为连接器的执行引擎，以适应企业现有的技术组件。SeaTunnel支持多个版本的Spark和Flink。
- JDBC多路复用，数据库日志多表解析:SeaTunnel支持多表或整个数据库同步，解决了JDBC过度连接的问题;支持多表或全数据库的日志读取和解析，解决了CDC多表同步场景需要处理日志重复读取和解析的问题。
- 高吞吐量和低延迟:SeaTunnel支持并行读写，提供稳定可靠的高吞吐量和低延迟的数据同步能力。
- 完善的实时监控:SeaTunnel支持对数据同步过程中每一步的详细监控信息，让用户轻松了解同步任务读写的数据数量、数据大小、QPS等信息。
- 支持两种作业开发方法:编码和画布设计。SeaTunnel web项目https://github.com/apache/seatunnel-web提供了作业、调度、运行和监控功能的可视化管理
SeaTunnel系统架构设计
SeaTunnel 安装部署
SeaTunnel 引擎是 SeaTunnel 的默认引擎。SeaTunnel的安装包中已经包含了SeaTunnel Engine的全部内容
SeaTunnel 安装包获取
- 可以通过直接下载编译的包进行安装
https://dlcdn.apache.org/seatunnel/2.3.3/apache-seatunnel-2.3.3-bin.tar.gz
下载完毕之后上传到服务器上面并解压
# 解压到了/opt/module目录下
tar -zxvf apache-seatunnel-2.3.3-bin.tar.gz -C /opt/module
- 通过源代码方式进行编译获取安装包
- 从https://seatunnel.apache.org/download或https://github.com/apache/seatunnel.git获取源码包
- 使用maven命令构建安装包
./mvnw -U -T 1C clean install -DskipTests -D"maven.test.skip"=true -D"maven.javadoc.skip"=true -D"checkstyle.skip"=true -D"license.skipAddThirdParty" - 然后就可以在 中获取安装包
${Your_code_dir}/seatunnel-dist/target，例如：apache-seatunnel-2.3.3-SNAPSHOT-bin.tar.gz
配置 SEATUNNEL_HOME
安装Connectors插件
从2.2.0-beta开始，二进制包默认不提供connectors的依赖，因此在第一次使用它时，需要执行以下命令来安装连接器:(当然，您也可以从Apache Maven Repository[https://repo.maven.apache.org/maven2/org/apache/seatunnel/]手动下载连接器，然后手动移动到connectors/seatunnel目录)
sh bin/install-plugin.sh 2.3.3
如果需要指定connector的版本，以2.3.3版本为例，需要执行
sh bin/install-plugin.sh 2.3.3
一般情况下我们不需要所有的连接器插件，所以你可以通过配置config/plugin_config来指定你需要的插件，例如，你只需要connector-console插件，然后你可以修改plugin.properties,比如
--seatunnel-connectors--
connector-console
--end--
如果希望示例应用程序正常工作，则需要添加以下插件
--seatunnel-connectors--
connector-fake
connector-console
--end--
你可以在${SEATUNNEL_HOME}/connectors/plugins-mapping.properties下找到所有支持的连接器和相应的plugin_config配置名称
如果想手动安装V2 connector插件，只需要下载自己需要的V2 connector插件，放到${SEATUNNEL_HOME}/connectors/seatunnel目录下即可
启动示例作业
定义一个作业配置文件
我们可以直接使用官方的模版config/v2.batch.config.template, 该模版分别定义了env、source、sink
env：表示运行的参数设置，比如并发数，作业运行模式：BATCH/STRAM、checkpoint等等
source：表示数据源的定义
sink：表示目标端的数据源定义
执行命令：
./bin/seatunnel.sh --config ./config/v2.batch.config.template -e local
我是用的2.3.3，在运行后会报错，提示缺少：java.lang.NoClassDefFoundError: com/sun/jersey/client/impl/CopyOnWriteHashMap

Seatunnel示例：mysql-to-mysql
接下来，我们在测试一下使用seatunnel实现从mysql同步到mysql的配置
首先，需要下载mysql jdbc的的依赖，这里我们可以选择在plugin-mapping.properties文件中配置connector-jdbc ，也可以直接将connector-jdbc的jar包放入到 $SEATUNNEL_HOME//connectors/seatunnel 下面
创建mysql库和表
create database test_01;
create table test_01.user(userid int(4) primary key not null auto_increment,username varchar(16) not null);
create database test_02;
create table test_02.user(userid int(4) primary key not null auto_increment,username varchar(16) not null);
插入数据
insert into test_01.user (username) values ("zhangsan");
insert into test_01.user (username) values ("lisi");
创建同步配置文件
env {
job.mode = "BATCH"
}
# 配置数据源
source {
jdbc {
url = "jdbc:mysql://172.1.1.54:3306/test_01"
driver = "com.mysql.cj.jdbc.Driver"
user = "admin"
password = "xxxxxxx"
generate_sink_sql = true
database = "test_01"
table = "user"
query = "select * from test_01.user"
}
}
transform {
}
# 配置目标库
sink {
jdbc {
url = "jdbc:mysql://172.1.1.54:3306/test_02"
driver = "com.mysql.cj.jdbc.Driver"
user = "admin"
password = "xxxxxx"
generate_sink_sql = true
database = "test_02"
table = "user"
}
}
运行命令：
./bin/seatunnel.sh -e LOCAL -c ./config/mysql-to-mysql.conf
输出如下信息表示同步成功：

Seatunnel 集成Flink&Spark引擎
编辑seatunnel-env.sh文件
修改FLINK_HOME为flink部署目录
修改Spark_HOME为spark部署目录
FLINK_HOME = /data/flink-1.14.5/
SPRK_HOME = /data/spark-2.4.6/
启动Flink集群
./bin/start_cluster.sh
执行命令，还是拿mysql-to-msyq.conf 为例
注意：如果是同步mysql的话，需要将jdbc的jar包放在flink/lib目录下，这次其实和使用flink做一些数据同步一样，相关的依赖包都给到flink。
./bin/start-seatunnel-flink-15-connector-v2.sh --config ./config/mysql-to-mysql.conf
执行结果如下：
Execute SeaTunnel Flink Job: ${FLINK_HOME}/bin/flink run -c org.apache.seatunnel.core.starter.flink.SeaTunnelFlink /mnt/apache-seatunnel-2.3.3/starter/seatunnel-flink-13-starter.jar --config ./config/mysql-to-mysql.conf --name SeaTunnel
