Debezium kafka connect连接器未成功更新

Question

我正在尝试使用Debezium和kafka。我已经在table.whitelist属性中注册了一个包含3个表的连接器，并且它正常工作。下面是运行连接器的配置。

{"name":"xoom-eds-extactor","config":{"connector.class":"io.debezium.connector.mysql.MySqlConnector","database.user":"debezium","database.server.id":"1","database.hostname":"qa514dtc001.ord.qa001.xoom.com","database.password":"xoom123","database.history.kafka.bootstrap.servers":"eds-kafka1:9092","database.history.kafka.topic":"dbhistory.inventory","name":"xoom-eds-extactor","database.server.name":"MySQL-Database-Docker","database.port":"3306","include.schema.changes":"true","table.whitelist":"xoom_eds_extraction_src_db_mock.postal_code_mock,xoom_eds_extraction_src_db_mock.account_number_mock,xoom_eds_extraction_src_db_mock.credit_card_number_mock,xoom_eds_extraction_src_db_mock.ip_address_details_mock,xoom_eds_extraction_src_db_mock.university_details_mock"},"tasks":[{"connector":"xoom-eds-extactor","task":0}],"type":"source"}

命令：

curl -X PUT -H "Content-Type: application/json" --data @xoom-eds-extactor-conf.json "http://eds-kafka1:8083/connectors/xoom-eds-extactor/config"

配置json：

{
   "name":"xoom-eds-extactor",
   "connector.class":"io.debezium.connector.mysql.MySqlConnector",
   "database.hostname":"qa514dtc001.ord.qa001.xoom.com",
   "database.port":"3306",
   "database.user":"debezium",
   "database.password":"xoom123",
   "database.server.id":"1",
   "database.server.name":"MySQL-Database-Docker",
   "database.history.kafka.bootstrap.servers":"eds-kafka1:9092",
   "database.history.kafka.topic":"dbhistory.inventory",
   "include.schema.changes":"true",
"table.whitelist":"xoom_eds_extraction_src_db_mock.postal_code_mock,xoom_eds_extraction_src_db_mock.account_number_mock,xoom_eds_extraction_src_db_mock.credit_card_number_mock,xoom_eds_extraction_src_db_mock.ip_address_details_mock,xoom_eds_extraction_src_db_mock.university_details_mock"
}

这将成功执行，但当我列出Kafka主题时，只有最后3个主题出现，2个新的主题没有添加。

MySQL-Database-Docker
MySQL-Database-Docker.xoom_eds_extraction_src_db_mock.account_number_mock
MySQL-Database-Docker.xoom_eds_extraction_src_db_mock.credit_card_number_mock
MySQL-Database-Docker.xoom_eds_extraction_src_db_mock.postal_code_mock
__consumer_offsets
connect-configs
connect-offsets
connect-status
dbhistory.inventory

据我所知，有一个旧的未决PR与此问题相关，它应该在0.9.1版本中修复。但如果您使用的是旧版本，您可以简单地按照以下步骤操作。

• 添加新表，但暂不写入
• 关闭连接器
• 更改筛选器配置并将快照模式设置为“schema_only_recovery”
• 删除（或重命名）现有数据库历史记录主题
• 重新启动连接器；这将重新创建DB架构的内部历史记录，然后继续从先前记录的偏移量进行流式传输
• 开始写入新表

至少这是我们所做的（我们仍在使用0.8.2)。
