如何从 spring 云数据流创建主题?

how to create a topic from spring cloud data flow?

我正在尝试将我的源的最后读取记录存储在 kafka 中的一个单独主题中作为流源。我如何使用 spring 云数据流应用程序实现此目的。任何建议都会有很大帮助..

Spring Cloud Stream 应用程序可以支持多个目的地。

您可以添加第二个输出目标并向其发送消息。

I want to use the RDBMS as a source. The current JDBC app starter needs an extra flag in the source table to mark the row as read..but most of the scenarios, that wont be possible..So I am trying to build it based on timestamp.. So I will be storing the last read timestamp in a separate topic.. and each time i will use this timestamp, to continue reading from the RDBMS(incremental load)

您可以在启动时从主题中消费以获得初始值。
