Question

由于不可能更新debezium连接器 [DBZ-175]，因此我试图创建多个连接器以容纳新表。但是，当我通过curl命令注册新的连接器时，以前的连接器失败。总是最新的连接器处于活动状态，而以前的所有连接器均失败。

当我检查先前连接器的状态时，输出如下：

   "connector":{  
      "state":"RUNNING",
      "worker_id":"10.0.0.216:8083"
   },

我正在使用的连接器配置为：连接器1

sudo curl -X POST -H "Accept:application/json"  -H "Content-Type:application/json" http://localhost:8083/connectors/  -d '{ "name": "mysql-connector-root-user", "config": { "connector.class": "io.debezium.connector.mysql.MySqlConnector", "database.hostname": "10.0.0.160", "database.port": "3306", "database.user": "root", "database.password": "root12345", "database.server.id": "2", "database.server.name": "MySql-root", "database.history.kafka.bootstrap.servers": "10.0.0.160:9093,10.0.0.216:9093", "database.history.kafka.topic": "database_history_2" , "include.schema.changes": "true", "table.whitelist": "Debezium_test.recipes" } }'

连接器2

sudo curl -X POST -H "Accept:application/json"  -H "Content-Type:application/json" http://localhost:8083/connectors/  -d '{ "name": "mysql-connector-root-user2", "config": { "connector.class": "io.debezium.connector.mysql.MySqlConnector", "database.hostname": "10.0.0.160", "database.port": "3306", "database.user": "root", "database.password": "root12345", "database.server.id": "3", "database.server.name": "MySql-root2", "database.history.kafka.bootstrap.servers": "10.0.0.160:9093,10.0.0.216:9093", "database.history.kafka.topic": "database_history_3" , "include.schema.changes": "true", "table.whitelist": "test.person_details" } }'

对此将提供任何帮助。

同一MySql数据库的多个Debezium连接器不起作用
