MySQL CDC

MySQL CDC source 连接器

支持这些引擎

SeaTunnel Zeta
Flink

描述

MySQL CDC连接器允许从MySQL数据库读取快照和增量数据. 本文档描述了如何配置MySQL CDC连接器以对MySQL数据库运行SQL查询.

主要功能

支持的数据源信息

数据源	支持的版本	Driver	Url	Maven
MySQL	MySQL: 5.5, 5.6, 5.7, 8.0.x RDS MySQL: 5.6, 5.7, 8.0.x	com.mysql.cj.jdbc.Driver	jdbc:mysql://localhost:3306/test	https://mvnrepository.com/artifact/mysql/mysql-connector-java/8.0.28

依赖

安装Jdbc驱动

对于Flink引擎

你需要确保 jdbc 驱动 jar package 已经放在目录 ${SEATUNNEL_HOME}/plugins/.

对于SeaTunnel Zeta引擎

你需要确保 jdbc 驱动 jar package 已经放在目录 ${SEATUNNEL_HOME}/lib/.

创建MySQL用户

你必须定义一个MySQL用户，该用户对Debezium MySQL连接器所监控的所有数据库拥有适当的权限.

创建MySQL用户:

mysql> CREATE USER 'user'@'localhost' IDENTIFIED BY 'password';

给用户赋予所需权限:

mysql> GRANT SELECT, RELOAD, SHOW DATABASES, REPLICATION SLAVE, REPLICATION CLIENT ON *.* TO 'user' IDENTIFIED BY 'password';

最终确定用户权限:

mysql> FLUSH PRIVILEGES;

启用MySQL Binlog

一定要为MySQL复制启用binlog。binlog记录事务更新以供复制工具传播更改.

检查log-bin是否已经设置为on:

mysql> show variables where variable_name in ('log_bin', 'binlog_format', 'binlog_row_image', 'gtid_mode', 'enforce_gtid_consistency');
+--------------------------+----------------+
| Variable_name            | Value          |
+--------------------------+----------------+
| binlog_format            | ROW            |
| binlog_row_image         | FULL           |
| enforce_gtid_consistency | ON             |
| gtid_mode                | ON             |
| log_bin                  | ON             |
+--------------------------+----------------+

如果log_bin的值不是on, 配置你的MySQL server配置文件($MYSQL_HOME/mysql.cnf)，配置文件中包含以下属性，这些属性在以下表格中有描述:

# Enable binary replication log and set the prefix, expiration, and log format.
# The prefix is arbitrary, expiration can be short for integration tests but would
# be longer on a production system. Row-level info is required for ingest to work.
# Server ID is required, but this will vary on production systems
server-id         = 223344
log_bin           = mysql-bin
expire_logs_days  = 10
binlog_format     = row
# mysql 5.6+ requires binlog_row_image to be set to FULL
binlog_row_image  = FULL

# optional enable gtid mode
# mysql 5.6+ requires gtid_mode to be set to ON, but not required by mysql 8.0+
gtid_mode = on
enforce_gtid_consistency = on

重启MySQL Server

/etc/inint.d/mysqld restart

修改之后再检查一次binlog的状态:

MySQL 5.5:

mysql> show variables where variable_name in ('log_bin', 'binlog_format', 'binlog_row_image', 'gtid_mode', 'enforce_gtid_consistency');
+--------------------------+----------------+
| Variable_name            | Value          |
+--------------------------+----------------+
| binlog_format            | ROW            |
| log_bin                  | ON             |
+--------------------------+----------------+

MySQL 5.6+:

mysql> show variables where variable_name in ('log_bin', 'binlog_format', 'binlog_row_image', 'gtid_mode', 'enforce_gtid_consistency');
+--------------------------+----------------+
| Variable_name            | Value          |
+--------------------------+----------------+
| binlog_format            | ROW            |
| binlog_row_image         | FULL           |
| enforce_gtid_consistency | ON             |
| gtid_mode                | ON             |
| log_bin                  | ON             |
+--------------------------+----------------+

MySQL 8.0+:

show variables where variable_name in ('log_bin', 'binlog_format', 'binlog_row_image', 'gtid_mode', 'enforce_gtid_consistency')
+--------------------------+----------------+
| Variable_name            | Value          |
+--------------------------+----------------+
| binlog_format            | ROW            |
| binlog_row_image         | FULL           |
| enforce_gtid_consistency | OFF            |
| gtid_mode                | OFF            |
| log_bin                  | ON             |
+--------------------------+----------------+  
     

提示

配置MySQL session超时时长

当为大型数据库初始一致快照时，已建立的连接可能在读取表时超时。可以通过在MySQL配置文件中配置interactive_timeout（交互超时时间）和wait_timeout（等待超时时间）来防止这种行为.

interactive_timeout: 服务器在关闭交互连接之前等待活动（交互操作）的秒数. 详见 MySQL’s documentation.
wait_timeout: 服务器在关闭非交互式连接之前等待其活动的秒数. 详见 MySQL’s documentation.

更多的数据库配置，见 Debezium MySQL Connector

username	String	是	-	用来连接到数据库服务的数据库名称.
password	String	是	-	连接到数据库服务所使用的密码.
database-names	List	否	-	要监控的数据库名称.
database-pattern	String	否	.*	要捕获的数据库名称的正则表达式, 例如: `database_prefix.*`.
table-names	List	是	-	要监控的表名. 表名需要包括库名, 例如: `database_name.table_name`
table-pattern	String	是	-	要捕获的表名称的正则表达式. 表名需要包括库名, 例如: `database.\\.table_.`
table-names-config	List	否	-	表配置的列表集合. 例如: [{"table": "db1.schema1.table1","primaryKeys": ["key1"],"snapshotSplitColumn": "key2"}]
startup.mode	Enum	否	INITIAL	MySQL CDC 消费者的可选启动模式, 有效枚举值为 `initial`, `earliest`, `latest` 和 `specific`. `initial`: 启动时同步历史数据, 然后同步增量数据. `earliest`: 从尽可能最早的偏移量开始启动. `latest`: 从最近的偏移量启动. `specific`: 从用户提供的特定偏移量开始启动.
startup.specific-offset.file	String	否	-	从指定的binlog日志文件名开始. 注意, 当使用 `startup.mode` 选项为 `specific` 时，此选项为必填项.
startup.specific-offset.pos	Long	否	-	从指定的binlog日志文件位置开始. 注意, 当使用 `startup.mode` 选项为 `specific` 时，此选项为必填项.
stop.mode	Enum	否	NEVER	MySQL CDC 消费者的可选停止模式, 有效枚举值为 `never`, `latest` 和 `specific`. `never`: 实时任务一直运行不停止. `latest`: 从最新的偏移量处停止. `specific`: 从用户提供的特定偏移量处停止.
stop.specific-offset.file	String	否	-	从指定的binlog日志文件名停止. 注意, 当使用 `stop.mode` 选项为 `specific` 时，此选项为必填项.
stop.specific-offset.pos	Long	否	-	从指定的binlog日志文件位置停止. 注意, 当使用 `stop.mode` 选项为 `specific` 时，此选项为必填项.
snapshot.split.size	Integer	否	8096	表快照的分割大小（行数）,读取表的快照时,被捕获的表会被分割成多个分割块.
snapshot.fetch.size	Integer	否	1024	每次轮询读取表快照时的最大获取大小.
server-id	String	否	-	此数据库客户端的数字 ID 或数字 ID 范围, 数字 ID 的语法如 `5400`, 数字 ID 范围的语法如 '5400-5408'. 每个 ID 在 MySQL 集群中所有当前正在运行的数据库进程里必须是唯一的. 此连接加入 MySQL服务以另外一个服务的身份 (带有此唯一 ID) 以便于能够读取binlog. 默认情况下, 会生成一个介于 6500 到 2,148,492,146 之间的数字, 然而我们建议设置一个明确的值.
server-time-zone	String	否	UTC	数据库服务中的会话时区. 如果没设置, 使用 ZoneId.systemDefault() 来确定服务的时区.
connect.timeout.ms	Duration	否	30000	连接器在尝试连接数据库服务器后，在超时之前应等待的最长时间.

connection.pool.size	Integer	否	20	jdbc连接池大小.
chunk-key.even-distribution.factor.upper-bound	Double	否	100	块键分布因子的上限. 该因子用于确定表数据是否分布均匀. 如果分布式因子计算结果小于或等于此上限 (即., (MAX(id) - MIN(id) + 1) / row count), 表的分块将被优化以实现均匀分布. 否则, 如果分布因子大于此上限, 该表将被视为分布不均, 并且如果估计的分片数量超过 `sample-sharding.threshold` 所指定的值, 则将使用基于采样的分片策略. 默认值是100.0.
chunk-key.even-distribution.factor.lower-bound	Double	否	0.05	块键分布因子的下限. 该因子用于确定表数据是否分布均匀. 如果计算得出的分布因子大于或等于此下限 (即., (MAX(id) - MIN(id) + 1) / row count), 表的分块将被优化以实现均匀分布. 否则, 如果分布因子小于此下限, 该表将被视为分布不均, 并且如果预估的分片数量超过了 `sample-sharding.threshold` 所指定的值，则将使用基于采样的分片策略. 默认值是 0.05.
sample-sharding.threshold	Integer	否	1000	此配置指定了触发采样分片策略的预估分片数量阈值. 当分配因子超出由 `chunk-key.even-distribution.factor.upper-bound` 和 `chunk-key.even-distribution.factor.lower-bound` 所指定的范围时, 如果估计的分片数量 (按近似行数/块大小计算) 超过此阈值, 则将使用样本分片策略. 这有助于更高效地处理大型数据集. 默认值为 1000 分片.
inverse-sampling.rate	Integer	否	1000	采样分片策略中使用的采样率的倒数. 例如, 如果该值设置为 1000, 则表示在采样过程中应用了 1/1000 的采样率. 此选项在控制采样的粒度方面提供了灵活性, 从而影响最终的分片数量. 在处理非常大的数据集时非常有用, 因为此时更倾向于使用较低的采样率. 默认值为 1000.
exactly_once	Boolean	否	false	启用精确一次语义.
format	Enum	否	DEFAULT	MySQL CDC 的可选输出格式, 有效的枚举值为 `DEFAULT`、`COMPATIBLE_DEBEZIUM_JSON`.
schema-changes.enabled	Boolean	否	false	模式演进默认是禁用的. 当前我们只支持 `add column`、`drop column`、`rename column` 和 `modify column`.
debezium	Config	否	-	传递 Debezium的属性给Debezium嵌入式引擎, 该引擎用于捕获 MySQL 服务的数据变更.
common-options		否	-	Source插件通用参数, 详见 Source Common Options

任务示例

简单的示例

支持多表读取

env {
  parallelism = 1
  job.mode = "STREAMING"
  checkpoint.interval = 10000
}

source {
  MySQL-CDC {
    base-url = "jdbc:mysql://localhost:3306/testdb"
    username = "root"
    password = "root@123"
    table-names = ["testdb.table1", "testdb.table2"]
    
    startup.mode = "initial"
  }
}

sink {
  Console {
  }
}

支持向Kafka发送与Debezium兼容的格式

一定是使用kafka作为sink, 详见 compatible debezium format

支持表的自定义主键

env {
  parallelism = 1
  job.mode = "STREAMING"
  checkpoint.interval = 10000
}

source {
  MySQL-CDC {
    base-url = "jdbc:mysql://localhost:3306/testdb"
    username = "root"
    password = "root@123"
    
    table-names = ["testdb.table1", "testdb.table2"]
    table-names-config = [
      {
        table = "testdb.table2"
        primaryKeys = ["id"]
      }
    ]
  }
}

sink {
  Console {
  }
}

支持模式演变（表结构变更）

env {
  # You can set engine configuration here
  parallelism = 5
  job.mode = "STREAMING"
  checkpoint.interval = 5000
  read_limit.bytes_per_second=7000000
  read_limit.rows_per_second=400
}

source {
  MySQL-CDC {
    server-id = 5652-5657
    username = "st_user_source"
    password = "mysqlpw"
    table-names = ["shop.products"]
    base-url = "jdbc:mysql://mysql_cdc_e2e:3306/shop"
    
    schema-changes.enabled = true
  }
}

sink {
  jdbc {
    url = "jdbc:mysql://mysql_cdc_e2e:3306/shop"
    driver = "com.mysql.cj.jdbc.Driver"
    user = "st_user_sink"
    password = "mysqlpw"
    generate_sink_sql = true
    database = shop
    table = mysql_cdc_e2e_sink_table_with_schema_change_exactly_once
    primary_keys = ["id"]
    is_exactly_once = true
    xa_data_source_class_name = "com.mysql.cj.jdbc.MysqlXADataSource"
  }
}

表名支持正则以读取多个表

table-pattern 和 table-names 只能选择一个

env {
  # You can set engine configuration here
  parallelism = 1
  job.mode = "STREAMING"
  checkpoint.interval = 5000
  read_limit.bytes_per_second=7000000
  read_limit.rows_per_second=400
}

source {
  MySQL-CDC {
    server-id = 5652
    username = "st_user_source"
    password = "mysqlpw"
    database-pattern = "source.*"
    table-pattern = "source.*\\..*"
    base-url = "jdbc:mysql://mysql_cdc_e2e:3306"
  }
}

sink {
  Console {
  }
}
