+# Dlink 在 Flink-mysql-cdc 到 Doris 的实践
+
+## 背景
+
+Apache Doris是一个现代化的MPP分析型数据库产品。仅需亚秒级响应时间即可获得查询结果，有效地支持实时数据分析。例如固定历史报表，实时数据分析，交互式数据分析和探索式数据分析等。
+
+目前 Doris 的生态正在建设中，本文将分享如何基于 Dlink 实现 Mysql 变动数据通过 Flink 实时入库 Doris。
+
+## 准备
+
+老规矩，列清各组件版本：
+
+|      组件       |     版本     |
+| :-------------: | :----------: |
+|      Flink      |    1.13.3    |
+| Flink-mysql-cdc |    2.1.0     |
+|      Doris      | 0.15.1-rc09  |
+|   doris-flink   | 1.0-SNAPSHOT |
+|      Mysql      |    8.0.13    |
+|      Dlink      |    0.4.0     |
+
+需要注意的是，本文的 Doris 是基于 OracleJDK1.8 和 Scala 2.11 通过源码进行编译打包的，所以所有组件的 scala 均为 2.11，此处和 Doris 社区略有不同。
+
+## 部署
+
+本文的 Flink 和 Doris 的部署不做描述，详情请查阅官网。
+
+[Doris]: https://doris.apache.org/master/zh-CN/extending-doris/flink-doris-connector.html#%E4%BD%BF%E7%94%A8%E6%96%B9%E6%B3%95	"Doris"
+
+本文在 Dlink 部署成功的基础上进行，如需查看具体部署步骤，请阅读《flink sql 知其所以然（十六）：flink sql 开发企业级利器之 Dlink》。
+
+Dlink 的 plugins 下添加 `doris-flink-1.0-SNAPSHOT.jar` 和 `flink-sql-connector-mysql-cdc-2.1.0.jar` 。重启 Dlink。
+
+```java
+plugins/ -- Flink 相关扩展
+|- doris-flink-1.0-SNAPSHOT.jar
+|- flink-csv-1.13.3.jar
+|- flink-dist_2.11-1.13.3.jar
+|- flink-format-changelog-json-2.1.0.jar
+|- flink-json-1.13.3.jar
+|- flink-shaded-zookeeper-3.4.14.jar
+|- flink-sql-connector-mysql-cdc-2.1.0.jar
+|- flink-table_2.11-1.13.3.jar
+|- flink-table-blink_2.11-1.13.3.jar
+```
+
+当然，如果您想直接使用 FLINK_HOME 的话，可以在 `auto.sh` 文件中 `SETTING` 变量添加`$FLINK_HOME/lib` 。
+
+## 数据表
+
+### 学生表 （student）
+
+```sql
+-- Mysql
+DROP TABLE IF EXISTS `student`;
+CREATE TABLE `student`  (
+  `sid` int(11) NOT NULL,
+  `name` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
+  PRIMARY KEY (`sid`) USING BTREE
+) ENGINE = InnoDB CHARACTER SET = utf8 COLLATE = utf8_general_ci ROW_FORMAT = Dynamic;
+
+INSERT INTO `student` VALUES (1, '小红');
+INSERT INTO `student` VALUES (2, '小黑');
+INSERT INTO `student` VALUES (3, '小黄');
+```
+
+### 成绩表（score）
+
+```sql
+-- Mysql
+DROP TABLE IF EXISTS `score`;
+CREATE TABLE `score`  (
+  `cid` int(11) NOT NULL,
+  `sid` int(11) NULL DEFAULT NULL,
+  `cls` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
+  `score` int(11) NULL DEFAULT NULL,
+  PRIMARY KEY (`cid`) USING BTREE
+) ENGINE = InnoDB CHARACTER SET = utf8 COLLATE = utf8_general_ci ROW_FORMAT = Dynamic;
+
+INSERT INTO `score` VALUES (1, 1, 'chinese', 90);
+INSERT INTO `score` VALUES (2, 1, 'math', 95);
+INSERT INTO `score` VALUES (3, 1, 'english', 93);
+INSERT INTO `score` VALUES (4, 2, 'chinese', 92);
+INSERT INTO `score` VALUES (5, 2, 'math', 75);
+INSERT INTO `score` VALUES (6, 2, 'english', 80);
+INSERT INTO `score` VALUES (7, 3, 'chinese', 100);
+INSERT INTO `score` VALUES (8, 3, 'math', 60);
+```
+
+### 学生成绩宽表（scoreinfo）
+
+```sql
+-- Doris
+CREATE TABLE scoreinfo
+(
+    cid INT,
+    sid INT,
+    name VARCHAR(32),
+    cls VARCHAR(32),
+    score INT
+)
+UNIQUE KEY(cid)
+DISTRIBUTED BY HASH(cid) BUCKETS 10
+PROPERTIES("replication_num" = "1");
+```
+
+
+
+## FlinkSQL
+
+```sql
+CREATE TABLE student (
+    sid INT,
+    name STRING,
+    PRIMARY KEY (sid) NOT ENFORCED
+) WITH (
+'connector' = 'mysql-cdc',
+'hostname' = '127.0.0.1',
+'port' = '3306',
+'username' = 'test',
+'password' = '123456',
+'database-name' = 'test',
+'table-name' = 'student');
+CREATE TABLE score (
+    cid INT,
+    sid INT,
+    cls STRING,
+    score INT,
+    PRIMARY KEY (cid) NOT ENFORCED
+) WITH (
+'connector' = 'mysql-cdc',
+'hostname' = '127.0.0.1',
+'port' = '3306',
+'username' = 'test',
+'password' = '123456',
+'database-name' = 'test',
+'table-name' = 'score');
+CREATE TABLE scoreinfo (
+    cid INT,
+    sid INT,
+    name STRING,
+    cls STRING,
+    score INT,
+    PRIMARY KEY (cid) NOT ENFORCED
+) WITH (       
+'connector' = 'doris',
+'fenodes' = '127.0.0.1:8030' ,
+'table.identifier' = 'test.scoreinfo',
+'username' = 'root',
+'password'=''
+);
+insert into scoreinfo
+select 
+a.cid,a.sid,b.name,a.cls,a.score
+from score a
+left join student b on a.sid = b.sid
+```
+
+## 调试
+
+### 在 Dlink 中提交
+
+本示例采用了 yarn-session 的方式进行提交。

+
+上图可见，流任务已经成功被 Dlink 提交的远程集群了。
+
+### Doris 查询
+

+
+上图可见，Doris 已经被写入了历史全量数据。
+
+### 增量测试
+
+在 Mysql 中执行新增语句：
+
+```sql
+INSERT INTO `score` VALUES (9, 3, 'english', 100);
+```
+
+Doris 成功被追加：
+

+
+### 变动测试
+
+在 Mysql 中执行新增语句：
+
+```sql
+update score set score = 100 where cid = 1
+```
+
+Doris 成功被修改：

+## 简介
+
+Dlink 为 Apache Flink 而生，让 Flink SQL 更加丝滑。它是一个交互式的 FlinkSQL Studio，可以在线开发、补全、校验 、执行、预览 FlinkSQL，支持 Flink 官方所有语法及其增强语法，并且可以同时对多 Flink 集群实例进行提交、停止、SavePoint 等运维操作，如同您的 IntelliJ IDEA For Flink SQL。
+
+需要注意的是，Dlink 它更专注于 FlinkSQL 的应用，而不是 DataStream。在开发过程中您不会看到任何一句 java、scala 或者 python。所以，它的目标是基于 100% FlinkSQL 来实现批流一体的实时计算平台。
+
+值得惊喜的是，Dlink 的实现基于最新 Flink 源码二次开发，而交互更加贴近 Flink 的功能与体验，并且紧随官方社区发展。即站在巨人肩膀上开发与创新，Dlink 在未来批流一体的发展趋势下潜力无限。
