gripson opened a new issue #549: [rocketmq-connect-jdbc] Possible enhancements record URL: https://github.com/apache/rocketmq-externals/issues/549 The issue tracker is **ONLY** used for bug report and feature request. Any question or RocketMQ proposal please use our [mailing lists](http://rocketmq.apache.org/about/contact/). **FEATURE REQUEST** This is a recorder for issues I've met when deploying rocketmq-connect-runtime, and there are not many core-related or performance enhancements I can observe now, so I'll just put some simple enhancements as candidates. * [ ] Update Restful API template README.md file of jdbc connector. for example, Source connector Restful config: ``` http://${runtime-ip}:${runtime-port}/connectors/${rocketmq-jdbc-source-connector-name}?config={"source-rocketmq":"NameSrv-addr:9876","source-cluster":"${rocketmqTopic-topicRoute-cluster-value}","connector-class":"org.apache.rocketmq.connect.jdbc.connector.JdbcSourceConnector","dbUrl":"${source-db-ip}",dbPort”:"${source-db-port}",dbUsername":"${source-db-username}","dbPassword”:"${source-db-password}","rocketmqTopic":"jdbcTopic","mode":"bulk","whiteDataBase":{"${source-db-name}":{"${source-table-name}":{"${source-column-name}":"${source-column-value}"}}},"source-record-converter":"org.apache.rocketmq.connect.runtime.converter.JsonConverter"} ``` Since jdbc connector only can work successfully successfully when rocketmqTopic and topicNames are as same as ${source-table-name} of whiteDataBase, and there is same name database and tabke in target DBMS. * [ ] Issue of sending/receiving many messages than expectation: it produces duplicate data in target database, even there is only one row data in source database table. Test environment is both of source and target DBMS are MySQL.
