基于Flink1.13.3与hudi 0.10.0-release构建准实时数仓

xiaozhch5 • • Flink, Hudi, Kafka, Zeppelin, 其他, 大数据 • 阅读 587

本文基于Flink SQL与hudi构建准实时数仓，在Flink从kafka接入数据之后，即将所有数据存于hudi中，包括所有中间处理数据以及最终数据。文章《实时数仓|基于Flink1.11的SQL构建实时数仓探索实践 (qq.com)》描述了基于Flink SQL与kafka构建的实时数仓，本文以上述文章为基础。

在完成本文实践的同时可以同步参考上述文章。

最终结果：

基于Flink1.13.3与hudi 0.10.0-release构建准实时数仓

背景介绍

本文电商业务为例，展示准实时数仓的数据处理流程。

组件与配置说明

Flink 1.13.3

flink cdc 2.0.2

hudi 0.10.0 （2021.12.08最新发布版本，地址：https://github.com/apache/hudi/releases/tag/release-0.10.0）

hadoop 3.2.0

zeppelin 0.10.0

mysql 5.7（开启binlog）

kafka 2.5.0

由于zeppelin的便捷性，本文全部基于zeppelin进行任务提交，如果您还不会用zeppelin，那么您可以参考：https://lrting-top.blog.csdn.net/article/details/120681666。当然，如果您不想用zeppelin，用Flink SQL Client提交也是完全没有问题的。

本实验Flink开启checkpoint，设置为60s。

在完成以下任务之前，请确保您已经

  • 部署好Flink 1.13.3，并将hudi对应的Jar包已经正确打包并且放置到Flink的lib目录下，将flink cdc对应的jar包放置到lib目录下。
  • 部署并启动zeppelin 0.10.0，在zeppelin的Flink interpreter上指定了FLINK_HOME以及HADOOP_CLASSPATH
  • 同时还有启动hadoop、mysql、kafka

处理流程

基于Flink1.13.3与hudi 0.10.0-release构建准实时数仓

MySQL建表与原始数据载入

首先从以下地址获取mysql建表语句以及模拟数据：

https://obs-githubhelper.obs.cn-east-3.myhuaweicloud.com/blog-images/category/bigdata/hudi/flink-hudi-realtime/realtime_table.zip

下载了上述建表语句之后，进入mysql，新建realtime_dw_demo_1，进入数据库 realtime_dw_demo_1 ，初始化数据库

mysql -u root -p

create database realtime_dw_demo_1;

use database realtime_dw_demo_1;

source realtime_table.sql

将mysql表数据同步到kafka

使用flink cdc将mysql数据同步到kafka中，以下为相关sql语句：

读取mysql源表数据

%flink.ssql
insert into sku_info_topic_hudi select * from sku_info_topic_source;

基于上述步骤，我们把商品维表的基础数据同步到hudi中，同样我们使用商品维表创建dim_sku_info视图

%flink.ssql
drop view if exists dim_sku_info;
CREATE VIEW dim_sku_info AS
SELECT
  si.id AS id,
  si.sku_name AS sku_name,
  si.category3_id AS c3_id,

  c2.name AS c2_name,
  c3.id AS c1_id,
  c3.name AS c1_name
FROM
  sku_info_topic_hudi si 
  JOIN base_category3_hudi c3 ON si.category3_id = c3.id
  JOIN base_category2_hudi c2 ON c3.category2_id =c2.id
  JOIN base_category1_hudi c1 ON c2.category1_id = c1.id
;

DWD层数据处理

经过上面的步骤，我们已经将所用的维表已经准备好了。接下来我们将对ODS的原始数据进行处理，加工成DWD层的明细宽表。

%flink.ssql
drop table if exists ods_order_detail_topic;
drop table if exists ods_order_info_topic;

CREATE TABLE `ods_order_info_topic` (

  'connector' = 'kafka'
  ,'topic' = 'my5.order_info'
  ,'properties.bootstrap.servers' = '172.21.73.53:6667,172.21.73.54:6667,172.21.73.55:6667'
  ,'format' = 'debezium-json'
  ,'scan.startup.mode' = 'earliest-offset' 
  ,'properties.group.id' = 'hudiGroup'
);

CREATE TABLE dwd_paid_order_detail_hudi
(
  detail_id BIGINT,
  order_id BIGINT,
  user_id BIGINT,
  province_id INT,
  sku_id BIGINT,
  sku_name STRING,

  pay_time  TIMESTAMP(3),
  primary key (detail_id) not enforced
 ) WITH (
    'connector' = 'hudi',
    'path' = 'hdfs://host117:8020/realtime-demo-2/dwd_paid_order_detail_hudi',
    'scan.startup.mode' = 'earliest-offset',
    'table.type' = 'MERGE_ON_READ',
    'compaction.async.enabled' = 'false',
    'read.streaming.enabled' = 'true'
);

%flink.ssql

insert into dwd_paid_order_detail_hudi

  od.id,
  oi.id order_id,

    (

    WHERE order_status = '2' -- 已支付
    ) oi JOIN
    (
    SELECT *
    FROM ods_order_detail_topic
    ) od 
    ON oi.id = od.order_id;

ADS层数据

经过上面的步骤，我们创建了一张dwd_paid_order_detail明细宽表，并将该表存储在了hudi中。接下来我们将使用这张明细宽表与维表进行JOIN，得到我们ADS应用层数据。
