【问题描述】：

。我正在关注本教程 https://debezium.io/documentation/reference/tutorial.html 我看到了注册连接器的方法，但不知道如何删除/更新连接器。

curl -i -X POST -H "Accept:application/json" -H "Content-Type:application/json" localhost:8083/connectors/ -d ' "name": "inventory-connector", "config":  "connector.class": "io.debezium.connector.mysql.MySqlConnector", "tasks.max": "1", "database.hostname": "mysql", "database.port": "3306", "database.user": "debezium", "database.password": "dbz", "database.server.id": "184054", "database.server.name": "dbserver1", "database.include.list": "inventory", "database.history.kafka.bootstrap.servers": "kafka:9092", "database.history.kafka.topic": "dbhistory.inventory"  '

您能否也请指向我提到删除和更新连接器的文档页面。

【参考方案1】：

debezium connector 是一个标准的连接器，可以插入到 kafka connet 框架中。 Kafka Connect 框架支持多个 REST 命令以便与之交互。

要删除，请提交 DELETE 请求

curl -i -X DELETE localhost:8083/connectors/inventory-connector/

要更新配置，请使用新配置提交 PUT 请求

curl -i -X PUT -H "Accept:application/json" -H "Content-Type:application/json" localhost:8083/connectors/inventory-connector/config -d ' "connector.class": "io.debezium.connector.mysql.MySqlConnector", "tasks.max": "1", "database.hostname": "mysql", "database.port": "3306", "database.user": "debezium", "database.password": "dbz", "database.server.id": "184054", "database.server.name": "dbserver1", "database.include.list": "inventory", "database.history.kafka.bootstrap.servers": "kafka:9092", "database.history.kafka.topic": "dbhistory.inventory" '

【讨论】：

删除连接器时，无法重新创建同名的debezium。

@prakashpoudel 我认为这是因为删除连接器不会删除复制槽（在 Postgres 中），并且您不能有 2 个具有相同名称的槽。
