7. 第七章 Hudi案例实战

传智教育大数据分析平台，突出的是"真"，此项目是传智教育联合三方K12教育机构共同研发，并在上线发布后转换为课程，过程真实细致，采用主流的大数据技术和工具，主要针对客户（主要是学生）访问、咨询、线索、意向、报名、考勤等各类业务数据分析，根据分析结果优化平台的服务质量，最终满足用户的需求。教育大数据分析平台项目就是将大数据技术应用于教育培训领域，为企业经营提供数据支撑。

7.1 案例架构

本案例基于Flink SQL 与Hudi整合，将MySQL数据库业务数据，实时采集存储到Hudi表中，使用Presto和Flink SQL分别进行离线查询分析和流式查询数据，最后报表存储到MySQL数据库，使用FineBI整合进行可视化展示。
- 1、MySQL数据库：

传智教育客户业务数据存储及离线实时分析报表结果存储，对接可视化FineBI工具展示。

  • 2、Flink SQL 引擎

    使用Flink SQL中CDC实时采集MySQL数据库表数据到Hudi表，此外基于Flink SQL Connector整合Hudi与MySQL，数据存储和查询。

  • 3、Apache Hudi：数据湖框架

    传智教育业务数据，最终存储到Hudi表（底层存储：HDFS分布式文件系统），统一管理数据文件，后期与Spark和Hive集成，进行业务指标分析。

  • 4、Presto 分析引擎

    一个Facebook开源的分布式SQL查询引擎，适用于交互式分析查询，数据量支持GB到PB字节。

    本案例中直接从Hudi表加载数据，其中依赖Hive MetaStore管理元数据。其中Presto可以集成多数据源，方便数据交互处理。

  • 5、FineBI：报表工具

    帆软公司的一款商业图表工具, 让图表制作更加简单

7.2 业务数据

本次案例实战业务数据，来源于实际的客户Customer产生业务数据（咨询、访问、报名、浏览等），存储在MySQL数据库：itcast_nev ，使用业务表：

启动MySQL数据库，命令行方式登录，先创建数据库，再创建表，最后导入数据。

sql 复制代码 
[root@node1 ~]# mysql -uroot -p123456

CREATE DATABASE IF NOT EXISTS itcast_nev;
USE itcast_nev;

7.2.1 客户信息表

Flink 1.11 引入了 Flink SQL CDC，方便将RDBMS表数据，实时采集到存储系统，比如Hudi表等，其中MySQL CDC连接器允许从MySQL数据库读取快照数据和增量数据 。

7.3.1 开启MySQL binlog

MySQL CDC，需要首先开启MySQL数据库binlog日志，再重启MySQL数据库服务。

  • 第一步、开启MySQL binlog日志
powershell 复制代码 
[root@node1 ~]# vim /etc/my.cnf

在[mysqld]下面添加内容：

powershell 复制代码 
server-id=2
log-bin=mysql-bin
binlog_format=row
expire_logs_days=15
binlog_row_image=full
  • 第二步、重启MySQL Server
powershell 复制代码 
service mysqld restart

登录MySQL Client命令行，查看是否生效。

  • 第三步、下载Flink CDC MySQL Jar包
    由于使用Flink 1.12.2 版本，目前支持Flink CDC 版本：1.3.0，添加maven 依赖：
xml 复制代码 
<!-- https://mvnrepository.com/artifact/com.alibaba.ververica/flink-connector-mysql-cdc -->
<dependency>
    <groupId>com.alibaba.ververica</groupId>
    <artifactId>flink-connector-mysql-cdc</artifactId>
    <version>1.3.0</version>
</dependency>

如果使用Flink SQL Client，需要将jar包放到 $FLINK_HOME/lib 目录中：

7.3.2 环境准备

实时数据采集，既可以编写Java程序，又可以直接运行DDL语句。

  • 方式一：启动Flink SQL Client，执行编写DDL语句，Flink Job提交到Standalone集群
powershell 复制代码 
-- 启动HDFS服务
hadoop-daemon.sh start namenode 
hadoop-daemon.sh start datanode

-- 启动Flink Standalone集群
export HADOOP_CLASSPATH=`/export/server/hadoop/bin/hadoop classpath`
/export/server/flink/bin/start-cluster.sh

-- 启动SQL Client
/export/server/flink/bin/sql-client.sh embedded \
-j /export/server/flink/lib/hudi-flink-bundle_2.12-0.9.0.jar shell

-- 设置属性
set execution.result-mode=tableau;
set execution.checkpointing.interval=3sec;
SET execution.runtime-mode = streaming;
  • 方式二：使用IDEA创建Maven工程，添加相关依赖，编写程序，执行DDL语句。
    依赖pom.xml添内容如下：
xml 复制代码

编写程序，实现数据实时采集同步，主要三个步骤：输入表InputTable、输出表outputTable，查询插入INSERT...SELECT语句 ，示意图如下：

本次案例，为了更加只管看到效果，启动Flink SQL Client客户端，编写DDL和DML语句，直接执行。

7.3.3 实时采集数据

基于Flink CDC 实时采集数据，需要创建输入Input和输出Output两张表，再编写INSERT...SELECT 插入查询语句 。

接下来将MySQL数据库5张业务数据表数据，实时采集同步到Hudi表中（存储HDFS文件系统）。

7.3.3.1 客户信息表

同步客户信息表【customer】数据到Hudi表中，按照上述步骤编写DDL和DML语句并执行。

  • 第一步、输入表InputTable
sql 复制代码 
create table tbl_customer_mysql (
  id STRING PRIMARY KEY NOT ENFORCED,
  customer_relationship_id STRING,
  create_date_time STRING,
  update_date_time STRING,
  deleted STRING,
  name STRING,
  idcard STRING,
  birth_year STRING,
  gender STRING,
  phone STRING,
  wechat STRING,
  qq STRING,
  email STRING,
  area STRING,
  leave_school_date STRING,
  graduation_date STRING,
  bxg_student_id STRING,
  creator STRING,
  origin_type STRING,
  origin_channel STRING,
  tenant STRING,
  md_id STRING
)WITH (
  'connector' = 'mysql-cdc',
  'hostname' = 'node1.itcast.cn',
  'port' = '3306',
  'username' = 'root',
  'password' = '123456',
  'server-time-zone' = 'Asia/Shanghai',
  'debezium.snapshot.mode' = 'initial',
  'database-name' = 'itcast_nev',
  'table-name' = 'customer'
);
  • 第二步、输出表OutputTable
sql 复制代码 
CREATE TABLE edu_customer_hudi(
  id STRING PRIMARY KEY NOT ENFORCED,
  customer_relationship_id STRING,
  create_date_time STRING,
  update_date_time STRING,
  deleted STRING,
  name STRING,
  idcard STRING,
  birth_year STRING,
  gender STRING,
  phone STRING,
  wechat STRING,
  qq STRING,
  email STRING,
  area STRING,
  leave_school_date STRING,
  graduation_date STRING,
  bxg_student_id STRING,
  creator STRING,
  origin_type STRING,
  origin_channel STRING,
  tenant STRING,
  md_id STRING,
  part STRING
)
PARTITIONED BY (part)
WITH(
  'connector'='hudi',
  'path'= 'hdfs://node1.itcast.cn:8020/hudi-warehouse/edu_customer_hudi', 
  'table.type'= 'MERGE_ON_READ',
  'hoodie.datasource.write.recordkey.field'= 'id', 
  'write.precombine.field'= 'create_date_time',
  'write.tasks'= '1',
  'write.rate.limit'= '2000', 
  'compaction.tasks'= '1', 
  'compaction.async.enabled'= 'true',
  'compaction.trigger.strategy'= 'num_commits',
  'compaction.delta_commits'= '1',
  'changelog.enabled'= 'true'
);
  • 第三步、插入查询语句
sql 复制代码 
insert into edu_customer_hudi 
select *, CAST(CURRENT_DATE AS STRING) AS part from tbl_customer_mysql;

此时生成Flink job，提交到Standalone集群运行，首先将表中历史数据同步到Hudi表，再实时同步增量数据。

7.3.3.2 客户意向表

同步客户意向表【customer_relationship】数据到Hudi表中，按照上述步骤编写DDL和DML语句并执行。

  'path'= 'hdfs://node1.itcast.cn:8020/hudi-warehouse/edu_web_chat_ems_hudi', 
  'table.type'= 'MERGE_ON_READ',

);
  • 第三步、插入查询语句
sql 复制代码 
insert into edu_web_chat_ems_hudi 
select *, CAST(CURRENT_DATE AS STRING) AS part from tbl_web_chat_ems_mysql;

查看HDFS文件系统，同步全量数据存储Hudi目录：

至此将传智教育核心客户相关业务数据，采集同步到Hudi表中，此时5个Flink job依然在Standalone集群上运行，如果各个表中有业务数据产生，同样实时获取，存储到Hudi表中。

7.4 Presto 即席分析

使用Presto 分析Hudi表数据，最终将结果直接存储到MySQL数据库表中，示意图如下。

  • 第一、Hive 中创建表，关联Hudi表
  • 第二、Presto集成Hive，加载Hive表数据
  • 第三、Presto集成MySQL，读取或者保存数据

7.4.1 Presto 是什么

Presto是一款Facebook开源的MPP架构的OLAP查询引擎，可针对不同数据源执行大容量数据集的一款分布式SQL执行引擎。适用于交互式分析查询，数据量支持GB到PB字节。

  • 1、清晰的架构，是一个能够独立运行的系统，不依赖于任何其他外部系统。例如调度，presto自身提供了对集群的监控，可以根据监控信息完成调度。
  • 2、简单的数据结构，列式存储，逻辑行，大部分数据都可以轻易的转化成presto所需要的这种数据结构。
  • 3、丰富的插件接口，完美对接外部存储系统，或者添加自定义的函数。

官网：https://prestodb.io/

Presto采用典型的master-slave模型，由一个Coordinator节点，一个Discovery Server节点，多个Worker节点组成，Discovery Server通常内嵌于Coordinator节点中。

  • 1、coordinator(master)负责meta管理，worker管理，query的解析和调度
  • 2、worker则负责计算和读写
  • 3、discovery server， 通常内嵌于coordinator节点中，也可以单独部署，用于节点心跳。在下文中，默认discovery和coordinator共享一台机器。

Presto 数据模型：采取三层表结构

  • 1、catalog 对应某一类数据源，例如hive的数据，或mysql的数据
  • 2、schema 对应mysql中的数据库
  • 3、table 对应mysql中的表

7.4.2 Presto 安装部署

采用单节点部署安装Presto，服务器名称：node1.itcast.cn，IP地址：192.168.88.100。

  • 1、JDK8安装
powershell 复制代码 
java -version
  • 2、上传解压Presto安装包
powershell 复制代码 
# 创建安装目录
mkdir -p /export/server

# yum安装上传文件插件lrzsz
yum install -y lrzsz

# 上传安装包到node1的/export/server目录
presto-server-0.245.1.tar.gz

# 解压、重命名
tar -xzvf presto-server-0.245.1.tar.gz
ln -s presto-server-0.245.1 presto

#创建配置文件存储目录
mkdir -p /export/server/presto/etc
  • 3、配置presto

  • 4、启动服务
    进入Presto安装目录，执行 $PRESTO_HOME/bin中脚本
powershell 复制代码 
/export/server/presto/bin/launcher start

使用jps查看进程是否存在，进程名称：PrestoServer 。

此外WEB UI界面：

http://192.168.88.100:8090/ui/

  • 5、Presto CLI命令行客户端
    下载CLI客户端
powershell 复制代码 
presto-cli-0.241-executable.jar

上传presto-cli-0.245.1-executable.jar到/export/server/presto/bin

powershell 复制代码 
mv presto-cli-0.245.1-executable.jar presto
chmod +x presto

CLI客户端启动

powershell 复制代码 
/export/server/presto/bin/presto --server 192.168.88.100:8090

7.4.3 Hive 创建表

为了让Presto分析Hudi表中数据，需要将Hudi表映射关联到Hive表中。接下来，再Hive中创建5张传智教育客户业务数据表，映射关联到Hudi表。

启动HDFS服务、HiveMetaStore和HiveServer服务，运行Beeline命令行：

powershell 复制代码 
-- 启动HDFS服务
hadoop-daemon.sh start namenode 
hadoop-daemon.sh start datanode

-- Hive服务
/export/server/hive/bin/start-metastore.sh 
/export/server/hive/bin/start-hiveserver2.sh

-- 启动Beeline客户端
/export/server/hive/bin/beeline -u jdbc:hive2://node1.itcast.cn:10000 -n root -p 123456
设置Hive本地模式，方便测试使用：
-- 设置Hive本地模式
set hive.exec.mode.local.auto=true;
set hive.exec.mode.local.auto.tasks.max=10;
set hive.exec.mode.local.auto.inputbytes.max=50000000;

7.4.3.1 创建数据库

创建传智教育数据存储数据库database：

sql 复制代码 
-- 创建数据库
CREATE DATABASE IF NOT EXISTS edu_hudi ;
-- 使用数据库
USE edu_hudi ;

7.4.3.2 客户信息表

查看数据库表中数据：

使用Flink SQL流式查询Hudi表今日实时数据，统计离线指标对应今日实时指标，最后使用FineBI实时大屏展示。

基于Flink SQL Connector与Hudi和MySQL集成，编写SQL流式查询分析，在SQL Clientk客户端命令行执行DDL语句和SELECT语句。

7.5.1 业务需求

实时对传智教育客户每日业务数据进行基本指标统计，如下所示：

总共有5个指标，涉及到3张业务表：客户访问记录表、客户线索表和客户意向表，其中每个指标实时数据存储到MySQL数据库中一张表。

每个实时指标统计，分为三个步骤：

  • 第1步、创建输入表，流式加载Hudi表数据；
  • 第2步、创建输出表，实时保存数据至MySQL表；
  • 第3步、依据业务，编写SQL语句，查询输入表数据，并将结果插入输出表；

7.5.2 创建MySQL表

每个实时指标存储到MySQL数据库一张表，首先创建5个指标对应的5张表，名称不一样，字段一样，DDL语句如下：

  • 指标1：今日访问量
sql 复制代码 
CREATE TABLE `itcast_rpt`.`realtime_web_pv` (
  `report_date` varchar(255) NOT NULL,
  `report_total` bigint(20) NOT NULL,
  PRIMARY KEY (`report_date`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
  • 指标2：今日咨询量
sql 复制代码 
CREATE TABLE `itcast_rpt`.`realtime_stu_consult` (
  `report_date` varchar(255) NOT NULL,
  `report_total` bigint(20) NOT NULL,
  PRIMARY KEY (`report_date`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
  • 指标3：今日意向数
sql 复制代码 
CREATE TABLE `itcast_rpt`.`realtime_stu_intention` (
  `report_date` varchar(255) NOT NULL,
  `report_total` bigint(20) NOT NULL,
  PRIMARY KEY (`report_date`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
  • 指标4：今日报名人数
sql 复制代码 
CREATE TABLE `itcast_rpt`.`realtime_stu_apply` (
  `report_date` varchar(255) NOT NULL,
  `report_total` bigint(20) NOT NULL,
  PRIMARY KEY (`report_date`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
  • 指标5：今日有效线索量
sql 复制代码 
CREATE TABLE `itcast_rpt`.`realtime_stu_clue` (
  `report_date` varchar(255) NOT NULL,
  `report_total` bigint(20) NOT NULL,
  PRIMARY KEY (`report_date`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

7.5.3 实时指标分析

实时统计5个指标，加载3个Hudi表数据，如下所示：

  • 1、今日访问量和今日咨询量，流式加载表：edu_web_chat_ems_hudi 数据

  • 2、今日意向数和今日报名人数，流式加载表：edu_customer_relationship_hudi数据

  • 3、今日有效线索量，流式加载表：edu_customer_clue_hudi 数据

启动HDFS服务和Standalone集群，运行SQL Client客户端，设置属性：

powershell 复制代码
