Flink构造宽表实时入库案例介绍

1. 安装包准备

Flink 1.15.4 安装包

Flink cdc的mysql连接器

Flink sql的sdb连接器

MySQL驱动

SDB驱动

Flink jdbc的mysql连接器

 

2. 入库流程图

3. Flink安装部署

1. 上传Flink压缩包到服务器，并解压

tar -zxvf  flink-1.14.5-bin-scala_2.11.tgz  -C /opt/

1. 复制依赖至Flink中

cp sdb-flink-connector-3.4.8-jar-with-dependencies.jar /opt/flink-1.14.5/lib cp sequoiadb-driver-3.4.8.jre8.jar /opt/flink-1.14.5/lib cp flink-sql-connector-mysql-cdc-2.2.1.jar /opt/flink-1.14.5/lib cp flink-connector-jdbc_2.11-1.14.6.jar /opt/flink-1.14.5/lib

1. 修改flink-conf.yaml文件

vi conf/flink-conf.yaml ### 配置Master的机器名（IP地址） jobmanager.rpc.address: sdb1 ### 配置每个taskmanager 生成的临时文件夹 io.tmp.dirs: /opt/flink-1.14.5/tmp

1. 修改master文件

vi conf/masters #作为master的ip和端口号 upgrade1:8081

1. 修改worker文件

vi conf/workers #集群主机名 upgrade1 upgrade2 upgrade3

1. 拷贝到集群其他机器

scp -r /opt/flink-1.14.5 sdbadmin@upgrade2:/opt/ scp -r /opt/flink-1.14.5 sdbadmin@upgrade3:/opt/

1. 启动flink集群

[sdbadmin@upgrade1 flink-1.14.5]$ ./bin/start-cluster.sh

1. 启动flink-SQL

[sdbadmin@upgrade1 flink-1.14.5]$ ./bin/sql-client.sh

4. 实时入库

编写造数程序进行造数

4.1 环境准备

4.1.1 开启mysql的binlog

1. 创建binlog文件夹

[sdbadmin@upgrade1 mysql]$ mkdir /opt/sequoiasql/mysql/database/3306/binlog

1. 开启binlog

vim /opt/sequoiasql/mysql/database/3306/auto.cnf >>配置以下内容： log_bin=/opt/sequoiasql/mysql/database/3306/binlog binlog_format=ROW expire_logs_days=1 server_id=1

配置完成之后，重启mysql

[sdbadmin@upgrade1 mysql]$ ./bin/sdb_mysql_ctl stop myinst [sdbadmin@upgrade1 mysql]$ ./bin/sdb_mysql_ctl start myinst

4.1.2 创建mysql表

创建库

create database sbtest； use sbtest；

创建表

CREATE TABLE sbtest1 (     id INT UNSIGNED AUTO_INCREMENT,     uuid INT(10),     name1 CHAR(120),     age INT(4),     time1 DATETIME,     PRIMARY KEY(id) );

CREATE TABLE sbtest2 (     id INT UNSIGNED AUTO_INCREMENT,     uuid INT(10),     name2 CHAR(120),     age INT(4),     time1 DATETIME,     PRIMARY KEY(id) );

CREATE TABLE sbtest3 (     id INT UNSIGNED AUTO_INCREMENT,     uuid INT(10),     name3 CHAR(120),     age INT(4),     time1 DATETIME,     PRIMARY KEY(id) );

创建flink入库表

CREATE TABLE sbtest4 (     id INT UNSIGNED AUTO_INCREMENT,     uuid INT(10),     name1 CHAR(120),     name2 CHAR(120),     name3 CHAR(120),     age INT(4),     time1 DATETIME,     PRIMARY KEY(id) );

4.1.3 创建flink映射表

需要用到flink-sql-connector-mysql-cdc-2.2.1.jar

CREATE TABLE sbtest1_mysql (     id INT,     uuid INT,     name1 CHAR(120),     age INT,     time1 TIMESTAMP,     PRIMARY KEY (id) NOT ENFORCED   ) WITH (     'connector' = 'mysql-cdc',     'hostname' = '192.168.223.135',     'port' = '3306',     'username' = 'root',     'password' = 'root',     'database-name' = 'sbtest',     'table-name' = 'sbtest1' );

CREATE TABLE sbtest2_mysql (     id INT,     uuid INT,     name2 CHAR(120),     age INT,     time1 TIMESTAMP,     PRIMARY KEY (id) NOT ENFORCED   ) WITH (     'connector' = 'mysql-cdc',     'hostname' = '192.168.223.135',     'port' = '3306',     'username' = 'root',     'password' = 'root',     'database-name' = 'sbtest',     'table-name' = 'sbtest2' );

CREATE TABLE sbtest3_mysql (     id INT,     uuid INT,     name3 CHAR(120),     age INT,     time1 TIMESTAMP,     PRIMARY KEY (id) NOT ENFORCED   ) WITH (     'connector' = 'mysql-cdc',     'hostname' = '192.168.223.135',     'port' = '3306',     'username' = 'root',     'password' = 'root',     'database-name' = 'sbtest',     'table-name' = 'sbtest3' );

创建flink -->  mysql入库映射表

需要用到flink-connector-jdbc_2.11-1.14.6.jar

CREATE TABLE sbtest4_mysql (     id BIGINT,     uuid INT,     name1 CHAR(120),     name2 CHAR(120),     name3 CHAR(120),     age INT,     time1 TIMESTAMP,     PRIMARY KEY (id) NOT ENFORCED   ) WITH (     'connector' = 'jdbc',     'url' = 'jdbc:mysql://192.168.223.135:3306/sbtest',     'username' = 'root',     'password' = 'root',     'table-name' = 'sbtest4' );

创建flink -->  mysql入库映射表

需要用到sdb-flink-connector-3.4.8-jar-with-dependencies.jar

CREATE TABLE sbtest_sdb (     id BIGINT,     uuid INT,     name1 CHAR(120),     name2 CHAR(120),     name3 CHAR(120),     age INT,     time1 TIMESTAMP,     PRIMARY KEY (id) NOT ENFORCED ) WITH (     'connector' = 'sequoiadb',     'bulksize' = '1',     'hosts' = '192.168.223.135:11810',     'collectionspace' = 'sbtest',     'collection' = 'sbtest4' );

4.2 MySQL实时入库

4.2.1 Flink left join

select sdb1.id, sdb1.uuid, sdb1.name1, sdb2.name2, sdb3.name3, sdb1.age, sdb1.time1 from sbtest1_mysql sdb1 left join sbtest2_mysql sdb2 on sdb1.id = sdb2.id left join sbtest3_mysql sdb3 on sdb1.id = sdb3.id;

4.2.2 mysql实时入库

insert into sbtest4_mysql select sdb1.id, sdb1.uuid, sdb1.name1, sdb2.name2, sdb3.name3, sdb1.age, sdb1.time1 from sbtest1_mysql sdb1 left join sbtest2_mysql sdb2 on sdb1.id = sdb2.id left join sbtest3_mysql sdb3 on sdb1.id = sdb3.id;
